The best dual fuel generators for hurricanes are the ones that keep running after the gas stations close. Our top pick, the Westinghouse WGen9500DF, delivers 9500 running watts on gasoline and 8500 on propane with remote electric start, a transfer switch ready outlet and a 6.6 gallon tank. Below that, the Westinghouse iGen5000DF wins for quiet inverter power at 52 dBA, and the Pulsar G12KBN wins on tank size and 240V flexibility.
Hurricanes break the grid in two ways, and they break it in that order. Power goes out first. Fuel disappears second, often within hours, because everybody in the evacuation zone has the same idea at the same time. A gasoline-only generator solves the first problem and quietly becomes a lawn ornament during the second one. Stored liquid propane does not have that failure mode, and a dual fuel machine lets you burn through whatever you actually have on hand.
We spent weeks going through the full lineup of dual fuel portable generators, pulling published wattages for both fuels, tank capacities, noise figures and outlet counts, and then cross-referencing them against what owners actually report after a storm. Everything below names a specific fuel load, not an “up to” marketing figure, and every runtime number comes from the manufacturer spec rather than a guess. We updated the full comparison for 2026 as new models land.
One thing to sort out immediately, because it decides whether dual fuel is worth anything to you at all: dual fuel is not about efficiency. Propane costs more per hour to run and it is not more powerful. Prep forums are clear on this point. People choose dual fuel because sealed propane tanks keep for years without degrading, while gasoline in a jerry can on a garage shelf is a countdown clock. Read more about fuel types and run time capacity if you want the fuel chemistry side of this.

Two columns matter more than the rest for hurricane planning. The first is the propane running wattage, which is typically 10 to 15 percent below the gasoline figure on the same machine. The second is tank capacity, because tank capacity is how many hours you get before somebody has to move fuel in the dark during a rainstorm.
Why Dual Fuel Matters When the Gas Stations Run Dry
Gasoline is a timing problem. Unstabilized it starts breaking down in a matter of weeks, and owners on prep forums report gelling and varnish forming in carburetors within about six months of storage. Stabilized and rotated, sealed cans will hold up far longer, but storage in quantity is its own headache. You need ventilation, fire-safe containers, and a place away from the house, and most households do not have that.
Propane does not care. A sealed 20 lb cylinder stores indefinitely, and a grill cylinder or two in a shed is insurance that does not spoil. That is the entire argument, and it is why dual fuel won the prep forum consensus even though nobody claimed propane runs cheaper.
The catch is output. On every unit in this roundup, the propane figure is lower than the gasoline figure. The Westinghouse WGen9500DF drops from 9500 to 8500 running watts. The WEN DF680iX drops from 5100 to 4500. The Pulsar G12KBN drops from 9500 to 8550 on LPG. Plan your load list against the propane number, because that is the number that matters on day four when the gasoline is gone.
Switching is a mechanical operation, handled by a fuel selector valve and a separate propane fuel path. On the Westinghouse WGen9500DF it is a selector and a supplied hose. On the fuel pressure regulator side of the system, most manufacturers ship a low-pressure regulator with the generator, and a separate regulator is only needed if you are feeding it from a larger fixed installation.
1. Westinghouse WGen9500DF – Whole-Home Output with Remote Start
Westinghouse 12500 Watt Dual Fuel Home Backup Portable Generator, Remote Electric Start, Transfer Switch Ready, Gas and Propane Powered
9500W running on gasoline, 8500W on propane
457cc 4-stroke OHV with cast iron sleeve
6.6 gallon tank, up to 12 hours
210 pounds
+ Pros
- 9500 running watts on gasoline covers central air and a well pump
- Remote electric start with key fob plus recoil backup
- Transfer switch ready 30A and RV ready 50A outlets
- VFT display for voltage
- frequency and lifetime hours
- Includes oil
- funnel
- battery charger and propane hose
– Cons
- Open frame design is not weather enclosed
- 210 pounds needs two people to move
- Conventional output is not inverter clean for sensitive electronics
This is the unit we keep coming back to, because the numbers leave very little room for argument. 9500 running watts on gasoline, 12500 peak, and 8500 running on propane from the same 457cc engine. That is enough headroom to run a refrigerator, a freezer, a well pump and lights simultaneously, with spare capacity for a couple of window air conditioners.
The remote start is the feature that changes hurricane outcomes. You connect from inside, the engine catches, and you walk out to a machine that is already running. After a night of sleeping in a powered house during an outage, nobody wants to crouch in the dark behind a wet lawn trying to pull a cord. The recoil start is there as a backup, and the electric start has a key fob rather than a panel switch.
Owners rate the starting torque highly, and that is worth caring about because a well pump or a central air compressor is the load that trips weaker machines. The VFT display tracks voltage, frequency and lifetime hours, so you can see load draw while the storm is still in the county.
Gasoline and Propane Output Compared
The gas figure is 9500 running and 12500 peak watts. On propane you get 8500 running and 11200 peak. For a household that expects to run on propane for most of the outage, the practical question is whether 8500 continuous watts is enough, and for a typical house with a 3 to 5 ton air conditioner plus a refrigerator, freezer and lighting, it is comfortable rather than marginal.
The 457cc single cylinder with a cast iron sleeve is the same displacement used in the mid-size Pulsar, and the cast iron sleeve matters more than it sounds. Cast iron sleeves tolerate more extended run hours and more heat than the thin aluminum liners used in smaller open-frame machines, which is a real advantage for a generator that might run for 60 hours straight on a Friday.
Outlets and Transfer Switch Readiness
Six outlets total: two GFCI 20A household duplexes, one L14-30R 30A transfer switch ready outlet, and one 14-50R 50A RV ready outlet. That 30A twist lock is what makes it a legitimate whole-home machine rather than a handful of extension cords. With a transfer switch or a listed interlock kit, you can power essential circuits directly and skip the extension cord daisy chain that causes more storm damage than most generators do.
Runtime and Fuel Tank
The 6.6 gallon tank gives up to 12 hours on gasoline, measured at a partial load. In practice that means a night and most of a day before you refill. For hurricane planning, the fuel gauge on the panel matters more than the headline figure, because you should be able to read remaining level without walking over to the tank.
For Whom It Is Good
This suits a family with a well, a refrigerator, a freezer and either central air or a couple of window units, and it suits anyone who will not tolerate extension cords across a wet driveway. Remote start is the clincher for most households, because it converts a 2 a.m. chore into a 20 second one.
For Whom It Is Bad
It is not the right choice if you plan to run a home server, medical equipment or other sensitive electronics, since conventional open-frame output is not inverter clean. At 210 pounds it also is not a machine you carry up apartment stairs alone, and the open frame means it needs real shelter from rain, not a tarp that flaps all night.
2. Westinghouse iGen5000DF – Quiet Inverter Power at 52 dBA
Westinghouse 5000 Peak Watt Super Quiet Dual Fuel Portable Inverter Generator, Remote Electric Start, Gas & Propane Powered, RV Ready 30A Outlet, Parallel Capable, Blue/Black
3900 rated watts under 3 percent THD
52 dBA at rated output
3.4 gallon tank, up to 18 hours
104.7 pounds
+ Pros
- Lowest published noise figure in this lineup
- Inverter output under 3 percent THD is safe for electronics
- Up to 18 hours on a 3.4 gallon tank
- Remote electric start with key fob and recoil backup
- Parallel capable for double output
– Cons
- 3900 running watts is limited for central air and well pumps
- 104.7 pounds is heavy for a portable inverter
- Only two USB ports on the outlet mix
This is the one to buy if the generator will be running 20 feet from a bedroom window for three days. The published noise figure is 52 dBA, which is the lowest in this roundup by a clear margin and low enough that owners report holding a conversation nearby. Everything else about the machine is built around that same idea of being present in a house without being felt.
It is a true inverter, rated at 3900 running and 5000 peak watts with total harmonic distortion under 3 percent. That is laptop, monitor, medical device and CPAP territory. If your outage list includes anything with a circuit board, this is the machine and the open-frame units are not.
The remote start with key fob works here too, which you would not expect from a unit this quiet. The LED data center shows fuel level, power output, remaining run time, voltage and lifetime hours, all on a rotating display that is readable at a glance in the dark.
What 3 Percent THD Actually Means for Your Devices
Total harmonic distortion describes how much unwanted noise the inverter puts onto the power line. Conventional generators run somewhere in the 8 to 12 percent range, and motors and electronics on those lines heat up, run hot and occasionally fail. Under 3 percent is close to a utility-quality sine wave, which is why this class is the default recommendation for anything with sensitive circuitry.
During a hurricane the same logic covers a surprising number of ordinary loads. A refrigerator compressor is an inductive motor, a dehumidifier is a motor, a router is sensitive electronics. The inverter characteristic helps all three, and the 52 dBA figure is the other half of why owners keep this one indoors-adjacent.
Runtime on a Small Tank
Up to 18 hours on a 3.4 gallon tank, with an economy mode that cuts fuel burn when the load drops. This is a meaningful advantage in a storm: most households run a refrigerator and lights far below the 3900 watt rating for the majority of the outage, and the fuel savings during those low-load hours is what keeps the unit running through day four.
Outlets and Parallel Capability
Five outlets: a 120V 5-20R duplex, an RV ready TT-30R 30A outlet and two USB ports. The TT-30R is the right connector for an RV or a portable transfer device, but there is no 50A 120/240V output here, so you cannot feed a house subpanel through a full-size 50A transfer switch. The parallel capability lets you double output with a second matching unit if you have bought one and plan ahead.
For Whom It Is Good
It is for households where the outage load is a refrigerator, a freezer, internet, a few lights, a CPAP or oxygen concentrator, and where bedroom windows are closed. Owners running medical equipment during a grid event treat the low THD as the entire purchase justification, and it is a valid one.
For Whom It Is Bad
It is the wrong machine for a well pump plus a large air conditioner. 3900 running watts will run a well pump alone, but pairing it with central air means leaving one of them off. The 104.7 pound weight is also worth noting against the small sub-5000 watt inverters, though it is less than half the weight of the 9500 watt open-frame machines.
3. Pulsar G12KBN – 8-Gallon Tank and 50A Output
Pulsar G12KBN Heavy Duty Portable Dual Fuel Generator – 9500 Rated Watts & 12000 Peak Watts – Gas & LPG – Electric Start – Transfer Switch & RV Ready – CARB Compliant
9500 rated watts on gasoline, 8550 on LPG
8 gallon tank, 12 hours at half load
Seven outlets including 50A
457cc electric start
+ Pros
- 9500 rated watts on gasoline for whole-home backup
- Large 8 gallon tank gives long run times at half load
- Outlet mix includes 30A twist lock and 50A 120/240V
- 10 inch never-flat wheels and drop-down handles
- 3-in-1 digital meter with low oil shut-off
– Cons
- Only a 1 year limited warranty
- Conventional output is not inverter clean
- No remote start key fob included
- Open frame design offers no weather enclosure
This is the outlet-flexibility pick. Seven outlets is more than any other machine here, and the set includes a 50A 120/240V connector alongside a 30A twist lock, four 20A household duplexes and a 12V DC output. If you have an RV, a portable transfer device and a shop circuit all competing for the same generator, this avoids the adapter gymnastics.
The 8 gallon tank is the largest in the lineup and gives up to 12 hours at half load on gasoline. Combined with the 9500 rated gasoline wattage, it is a machine built for the “we do not know how long this will last” scenario.
Dual Fuel Figures and What the Derate Costs You
On gasoline the G12KBN is rated 9500 with 12000 peak. On LPG it drops to 8550 rated and 10800 peak. The roughly 10 percent drop is consistent with the rest of this roundup, and it is worth writing your load list against the 8550 figure if you expect to be on propane for most of the storm.
Owners specifically call out the LPG capability as the reason they bought it, since propane stores indefinitely in a shed while gasoline does not. The 3-in-1 digital meter reports voltage, frequency and running hours, which is the minimum instrumentation you want during a multi-day event.
Tank Size and Half-Load Endurance
Eight gallons at half load is 12 hours. For a household running the refrigerator, a few lights and a router, that is an entire day without touching a fuel can. It is a real advantage over the 4 gallon tanks in the mid-size class, and the 10 inch never-flat tires plus drop-down handles make moving 200-plus pounds of generator across a driveway or lawn far less of a chore.
The Warranty Catch
The 1 year limited warranty is the shortest here, and that is the one specification that gives us pause. Westinghouse and Champion machines in the same power class carry 3 year warranties. For a purchase that you hope to fire up twice a decade, warranty length is a reasonable proxy for manufacturer confidence, and this one scores lower than its competition.
For Whom It Is Good
It suits a household that needs a 50A connection, that has an RV or a workshop alongside the house, and that wants a large fuel tank. The outlet mix means fewer adapter swaps in the first ten minutes of an outage, which is when people are most likely to make mistakes.
For Whom It Is Bad
It is a poor fit for anyone with electronics that need clean power, and for anyone who wants to start it remotely from inside, since no key fob is included. The short warranty also matters if you intend to rely on it as a permanent piece of storm infrastructure rather than occasional backup.
4. DuroMax XP13000EH – 10500 Running Watts on a 500cc Engine
DuroMax XP13000EH 13,000-Watt Dual Fuel Portable Generator – Gas & Propane, Electric Start, Whole Home Backup Power, Transfer Switch Ready, RV & Emergency Ready
10500 running watts, 13000 starting watts
500cc 4-stroke electric start
50A transfer switch ready outlet
All-metal frame with copper windings
+ Pros
- 10500 running watts covers HVAC and household circuits
- Push-button electric start that also pull starts reliably
- Front-facing fuel selector for quick fuel switching
- All-metal frame and 100 percent copper windings
- Wheel and handle kit included with never-flat tires
– Cons
- Louder under load than small inverter models
- Higher total harmonic distortion than premium brands
- Arrives without engine oil
- Some units report heavy early oil consumption
At 10500 running watts on gasoline, the XP13000EH is the second highest output machine here and it pairs that with a 50A transfer switch ready outlet, an electric push-button start and a CO sensor. Owners describe powering entire homes through hurricanes on a single tank, which is the specific use case you are researching.
The all-metal frame and power panel with 100 percent copper windings is a durability argument rather than a performance one, and it is a reasonable one for a machine expected to sit outdoors through a season.
Fuel Switching and Engine Behavior
The front-facing fuel selector is the detail owners mention most. Switching between gasoline and propane takes seconds and does not require draining a tank, which is exactly what you need on day three when you are rationing. The 500cc four-stroke starts on the push button and will also pull start reliably, so a dead battery is an inconvenience rather than a crisis.
Output and Transfer Switch Use
The 50A outlet is the meaningful one for whole-home use. A 30A circuit will carry a refrigerator, lights, a router and maybe a small window unit. A 50A connection can take a 3 ton central air conditioner, a well pump, a refrigerator and a freezer at the same time, which is the list most households describe when they ask how big a generator they need for a 2000 square foot house.
Where Owners Report Problems
Noise is the recurring complaint, and it is not surprising. A 500cc conventional engine at full load is loud, and this is a machine for a driveway rather than a patio. Owners also note that it arrives without engine oil, so budget for that first fill. A minority report heavy oil consumption early in life and frustration with warranty service, which is worth weighing against the 3-year warranty being on paper.
For Whom It Is Good
It is for a household that wants central air and a well pump running at the same time and is willing to accept 230-plus pounds of open-frame machine in the yard. If you already plan to run a 50A transfer switch, this is the direct fit.
For Whom It Is Bad
Skip it for a bedroom-adjacent setup, a condo with noise rules, or a household with electronics that need clean power. At 234 pounds it is also the heaviest machine in this roundup, and the missing oil in the box is a small annoyance that catches people out every season.
5. Westinghouse WGen5300DFcv – Compact 5300W Unit with CO Sensor
Westinghouse 6500 Watt Dual Fuel Home Backup Portable Generator, Transfer Switch Ready 30A Outlet, RV Ready 30A Outlet, CO Sensor
5300 running watts on gasoline, 4800 on propane
4.7 gallon tank, up to 14.5 hours
120/240V volt selector switch
Automatic CO shutdown
+ Pros
- 5300 running watts covers essential home loads
- Compact footprint for its power class
- 120/240V selector switch adds real flexibility
- CO sensor with automatic shutdown
- Includes oil
- funnel
- propane hose and wheel kit
– Cons
- Open frame design is not weather enclosed
- Conventional output is not inverter clean
- 135.6 pounds needs two people to lift
- Magneto ignition rather than electric start
The WGen5300DFcv is the sensible middle of this lineup. 5300 running watts on gasoline and 4800 on propane is enough for a refrigerator, a freezer, a router, lights and a sump pump, and the footprint is small enough for a garage or a covered porch without eating the whole bay.
The automatic carbon monoxide shutdown is the safety feature that makes this worth a second look. Prep communities treat a missing CO sensor as a deal breaker, and having it cut the engine automatically is the difference between a nuisance and a hazard.
The 120/240V Selector and What It Buys You
The volt selector switch lets you run 120V household loads or step up to 240V for a heavier appliance. On the outlet side you get a 5-20R duplex, a TT-30R RV ready receptacle and an L14-30R transfer switch ready receptacle. The 30A twist lock is the one that matters for a house, because it is the standard connector for a listed interlock kit.
Runtime With a 4.7 Gallon Tank
Up to 14.5 hours on a 4.7 gallon tank with a fuel gauge on the panel. The 274cc four-stroke with a cast iron sleeve is a small engine but a durable one, and the tank size is generous for a machine in this class. Most owners running this during a storm are well below the 5300 watt rating most of the time, which stretches that figure further than the number suggests.
Ignition: The Thing to Know Before the Storm
This uses magneto ignition rather than electric start. That means no battery to fail in wet weather, which is genuinely a reliability advantage over an electric starter, but it also means you are outside pulling a cord. In a hurricane, that is a real difference between a machine that starts from the couch and one that does not.
For Whom It Is Good
It suits a household whose priority list is refrigerator, freezer, internet, medical device and sump pump, and whose storage space is tight. The CO sensor and low-oil shutdown give a family reasonable confidence to run it overnight without watching it.
For Whom It Is Bad
At 135.6 pounds it takes two people to lift, and conventional output rules it out for sensitive electronics. If your list includes central air, step up to a 9500 watt class machine instead.
6. Champion 4500W Electric Start – 21 Hours on a Propane Tank
Champion 4500-Watt Electric Start Dual Fuel Portable Inverter Generator
3500 running watts on gasoline, 3150 on propane
Up to 21 hours on propane
61 dBA noise output
2.25 gallon gasoline tank
+ Pros
- Up to 21 hours on propane for long outages
- 14 hours on gasoline from a 2.25 gallon tank
- 61 dBA suits a campsite or patio
- Electric start with a simple EZ Start dial
- CO Shield auto shutoff plus parallel ready
– Cons
- 99.2 pounds is heavy for a portable inverter
- CO sensor can be overly sensitive in enclosed spaces
- Oil draining needs a separate suction device
- Parallel kit sold separately
The headline number here is 21 hours on propane, which is the longest propane runtime in the roundup. That is what happens when a 3500 watt gasoline machine is matched to a 2.25 gallon gasoline tank and a 3150 watt propane rating: low load, long run, and enough output for a refrigerator, lights, a router and a television.
It is also the only machine here that pairs a genuine electric start with a sub-100 pound inverter-class dual fuel package that has CO Shield protection.
Electric Start, Intelligauge and the Simplicity Argument
The EZ Start dial reduces starting to turning a control and pressing a button, which matters in a wet driveway with a flashlight in your teeth. The Intelligauge power meter reports voltage, frequency and operating hours, so you can tell a failing battery from a failing alternator before you are stuck relying on this during a second outage.
Propane Endurance Math
21 hours on a standard propane cylinder at partial load is genuinely useful for a three-day event, and it is the reason dual fuel exists. Bring two cylinders and a spare, and a household running a modest load never touches gasoline at all. If you want to see how this compares across fuels, our generator fuel types and run time guide breaks down the numbers.
Noise and the CO Sensor Quirk
61 dBA is a reasonable outdoor figure and fine for a patio or a campsite. The specific complaint owners raise is the CO sensor being overly sensitive in enclosed truck beds or camper compartments, where it can shut the engine down even with ventilation. Place it outdoors on the manufacturer-specified clearance and the sensor behaves.
For Whom It Is Good
It is for a household with a moderate load that expects the outage to run for days, and for anyone who wants propane endurance plus the ability to start the machine without pulling a cord. It also works as an RV unit, where a smaller footprint and 61 dBA matter more than 240V whole-home output.
For Whom It Is Bad
It is too small for central air or a well pump paired with an air conditioner. At 99.2 pounds it is heavier than the other inverters here, and the parallel kit that doubles its output is a separate purchase, so plan for that if you intend to grow into more power.
7. WEN DF680iX – Electric Start Inverter for AC and EV Backup
WEN 6800-Watt Dual Fuel RV-Ready Electric Start Portable Inverter Generator with Fuel Shut Off and CO Watchdog for Electric Vehicle Backup (DF680iX)
5100 rated watts on gasoline, 4500 on propane
Bonded-neutral 240V for Level 2 charging
CO Watchdog shutdown
99.2 pounds
+ Pros
- Handles large RV air conditioners and multiple household loads
- About 12 hours on a standard 40 lb propane bottle
- Electric start that also starts easily on the pull cord
- Compact for a 6800 watt unit with wheels and telescoping handle
- Eight outlets covering L14-30R
- TT-30R
- USB and 12V DC
– Cons
- Noticeably loud under heavy load with multiple air conditioners
- Only two 120V household receptacles
- Propane quick connect fits a tank not a standard RV fitting
- Stabilizer feet can catch in lined storage compartments
The DF680iX is the odd one out in a hurricane roundup, and that is exactly why it is here. Its bonded-neutral 240V configuration is designed for low-power Level 2 electric vehicle charging and battery charging, so an EV owner can top up a car or a power station from the same machine that runs the refrigerator.
On fuel it is straightforward dual fuel: 5100 rated watts on gasoline, 4500 on propane, from a 224cc engine with electric start. Owners report running large RV air conditioners and multiple household loads, with roughly 12 hours on a 40 lb propane bottle.
Outlets and the 240V Question
Eight outlets: one L14-30R 120/240V, two 120V three-prong duplexes, one TT-30R RV receptacle, one 12V DC receptacle and two USB ports, plus a voltage selector switch. The L14-30R is the transfer switch ready connector, so this can back essential house circuits through a 30A interlock. The number of 120V duplexes is low at two, which is a real constraint if you are running a refrigerator, a freezer, a sump pump and lamps all on household circuits.
Noise Under Load
It is quiet at light load, particularly in Eco mode, and noticeably loud when multiple air conditioners are running at once. This is the same pattern the other inverter machines here show: the low headline figure describes a low-load condition, and the full-load number is what your neighbors hear on day two.
Propane Fitting and Storage Details
The tool-free propane quick connect attaches to a cylinder, not to a standard RV quick connect, so an RV owner needs a short adapter. Stabilizer feet can catch in a lined storage compartment, which is a minor irritation but worth knowing if you plan to stow it in a truck bed or a camper bay.
For Whom It Is Good
It is for EV owners, RV owners and anyone who wants inverter-clean 240V output from a package under 100 pounds. If your outage list includes charging a vehicle or a battery power station rather than running central air, the bonded-neutral 240V is the feature that makes this worth the purchase.
For Whom It Is Bad
Only two 120V household receptacles will force adapter use in a typical outage. It is also not for a house with central air and a well pump, since 4500 propane watts does not cover both, and the loudness under sustained heavy load can be a problem in close quarters.
8. Champion 4000W Dual Fuel – Under 52 Pounds with Clean Power
Champion 4000-Watt Dual Fuel RV Ready Portable Inverter Generator
4000 starting watts, 3000 running on gasoline
2700 running watts on propane
64 dBA at 23 feet
Less than 3 percent THD
51.8 pounds
+ Pros
- Under 52 pounds and easy to carry one-handed
- Clean inverter output under 3 percent THD
- CO Shield auto shutoff
- Overload reset button restarts without a full shutdown
- Fuel shutoff design for storage
– Cons
- Louder than smaller Champion models at full load
- Runs rough on propane until broken in on gasoline
- 1.54 gallon tank limits gasoline runtime
- Cannot run RV air conditioning and a microwave together
At 51.8 pounds with a fold-flat form factor, this is the machine you can carry from a car trunk to the garage step without recruiting help, which matters more than it sounds when the alternative is a flooded driveway in a 70 mph wind.
Output is 4000 starting and 3000 running watts on gasoline, 2700 running on propane, at less than 3 percent total harmonic distortion. That is clean power in a genuinely portable package.
Propane Runtime and the Break-In
Up to 10 hours on gasoline and up to 25 hours on propane. The 25 hour figure is the second longest here, and it comes from the same low-load-on-clean-power logic as the Champion 4500W. Owners do report that the engine runs rough on propane until it has been broken in on gasoline, so run it on gas for the first few hours after purchase before you depend on it in a storm.
Noise at 23 Feet
64 dBA at 23 feet is a published figure at a stated distance, which is more useful than a vague quiet claim. In practice owners find it acceptable for RV and campsite use and noticeably loud at full load compared with the smaller Champion models, which is normal for a 149cc engine being asked for more than it wants to give.
Safety and Storage Features
CO Shield shuts the engine down automatically when carbon monoxide levels rise. The fuel shutoff valve lets you drain the carburetor for storage, which is the single most effective anti-gumming measure you can take between seasons, and the overload reset button lets you clear a tripped breaker without shutting the machine down and restarting it.
For Whom It Is Good
It is for apartments, condos, small houses and anyone who cannot or will not move 100 pounds of generator. A refrigerator, a freezer, internet, chargers and lights is a realistic load, and the clean output lets you include a laptop or a monitor.
For Whom It Is Bad
It cannot run RV air conditioning and a microwave at the same time, and 3000 running watts is not a well-pump-plus-air-conditioner machine. The 1.54 gallon gasoline tank also means refilling twice a day if you are running it hard.
9. PowerSmart 3800W Inverter – 24 Hours on a Standard Propane Tank
PowerSmart 3800 Watt Dual Fuel Inverter Generator for Camping or Home Use
3300 running watts on gasoline, 3100 on propane
59 dBA in Eco Mode
Up to 24 hours on a 20 lb propane tank
50.7 pounds
+ Pros
- Up to 24 hours on a standard 20 lb propane tank
- 59 dBA in Eco Mode suits close placement
- Clean stable output with very stable voltage under load
- 50.7 pounds and light enough to move one-handed
- CO sensor with automatic shutdown plus cold start
– Cons
- 1.3 gallon gas tank needs frequent refills
- Noticeably louder as load increases
- Access panels and oil door need a Phillips screwdriver
- Recoil start only
- no electric start
The PowerSmart HB5040DC is the value inverter in this roundup, and the 24 hour propane runtime is the number that makes it interesting. That is longer than every other machine here except the Champion 4000W, on a 20 lb cylinder, from a package that weighs 50.7 pounds.
On gasoline it is 3300 running and 3800 starting watts, and on propane 3100 running and 3500 starting. Certified to ANSI/PGMA G300 and ANSI/UL2201, it carries the compliance marks that matter for a machine running unattended next to a house.
Propane Endurance and Small Tank Trade-Offs
Up to 24 hours on a 20 lb propane tank and 8 hours on gasoline at 25 percent load. The gasoline side is the weakness: a 1.3 gallon tank means several refills a day during a long event, and refilling at night in bad weather is exactly the scenario dual fuel is supposed to solve. Used primarily on propane, the small tank is a non-issue.
Noise, Outlets and Build Details
59 dBA at 25 percent load in Eco mode, with the machine getting noticeably louder as load rises. Outlets cover a 120V 30A L5-30R twist lock, a 20A duplex, a 12V DC port and dual USB ports, which is a complete panel for a small household. Access panels and the oil door require a Phillips screwdriver, a small irritation when the unit is in a dark garage.
Cold Start and CO Protection
Cold start technology plus an automatic CO sensor shutdown covers the two conditions most likely to cause a problem during a storm. The display panel shows real-time output and load, though owners note it is mounted low and hard to read, which matters if you are crouched behind a wet machine in the dark.
For Whom It Is Good
It is for a condo, an apartment with a balcony or a garage, and for anyone who wants long propane runtime in a small light package. Parallel ready means a second matching unit can double the output if you plan ahead.
For Whom It Is Bad
Recoil start only, so you are outside pulling a cord every time the power comes back. The 1.3 gallon gasoline tank and the rising noise under load both work against it as a primary whole-home machine.
10. WEN DF360iX – Lightest Dual Fuel Inverter in the Lineup
WEN Quiet and Lightweight 3600-Watt Dual Fuel RV-Ready Portable Inverter Generator with Fuel Shut Off and CO Watchdog (DF360iX)
2900 rated watts on gasoline, 2600 on propane
Pure sine wave inverter output
49 pounds
CO Watchdog and fuel shutoff
+ Pros
- Lightest dual fuel option here at 49 pounds
- Pure sine wave output protects sensitive electronics
- Handled a 12000 BTU air conditioner and a freezer in hurricane conditions
- CO Watchdog sensor and fuel shutoff aid safe storage
- Tool-free LPG quick-connector
– Cons
- Gasoline runtime is short at roughly 4 to 6 hours under load
- 30A RV plug is awkwardly placed and hard to seat
- Non-standard LPG quick connector is shorter than typical fittings
- Louder than larger engines under heavy load
At 49 pounds this is the lightest dual fuel machine in the roundup, and it earns that. One person can load it into a truck bed, carry it up a step, and reposition it as the storm track shifts. That portability is a safety feature as much as a convenience.
It produces 2900 rated watts on gasoline and 2600 on propane from a 149cc engine, as pure sine wave inverter output, which makes it safe for anything electronic.
Real Hurricane Load Reports
Owners report running a 12000 BTU air conditioner, refrigerators, a freezer, a computer and a coffee maker on this during hurricane conditions. That is a genuinely capable load list for 2900 rated watts, and it is the kind of report that matters more than a wattage number on a box, because it describes the loads people actually have during an outage.
The Gasoline Runtime Weakness
The 1.5 gallon tank gives roughly 4 to 6 hours under real load on gasoline, which is the shortest gasoline endurance in the roundup. On propane the picture is much better, and the fuel shutoff valve lets you drain the carburetor at season end. If you buy this, buy propane cylinders with it.
Fittings and Panel Ergonomics
The 30A RV plug sits awkwardly behind surrounding panelwork and is hard to fully seat, which is the most common fitting complaint. The LPG quick connector is a non-standard, slightly shorter fitting than typical propane hardware, so check that your hose or adapter fits before the storm. The digital data center tracks fuel level, load, voltage and run time.
For Whom It Is Good
It is for a household that wants clean power, low weight and quiet operation more than it wants high output. A window unit, a refrigerator, a freezer, internet and a computer is a realistic storm load list here.
For Whom It Is Bad
Do not plan on a long gasoline run, and do not expect it to carry a well pump and an air conditioner together. The 149cc engine also revs harder than a 212cc unit when you ask for real output.
11. WEN DF475T – Switchable 120V/240V at the Budget Tier
WEN 4,750-Watt 120V/240V Dual Fuel Portable Generator with Wheel Kit and Electric Start (DF475T)
3800 running watts on gasoline, 3500 on propane
Switchable 120V/240V output
4 gallon tank, up to 11 hours
105.8 pounds
+ Pros
- Covers most essential circuits at an entry price point
- Switchable 120V/240V output works with a transfer switch
- Electric key start is convenient and reliable
- 4 gallon tank delivers up to 11 hours at half load
- Wheel and handle kit included
– Cons
- Conventional output is not inverter clean for electronics
- Loud under load compared to inverter generators
- 105.8 pounds is heavy for one person to lift
- Small fuel capacity relative to larger dual fuel units
The DF475T is the entry point most first-time buyers land on, and for a refrigerator, a freezer, a few lights and a router during a short outage it does the job with an electric key start and a switchable 120V/240V output. That switchable output is the reason it can work with a transfer switch, which is unusual at this tier.
Output is 3800 running watts on gasoline and 3500 on propane, with 4750 and 4350 surge respectively, from a 224cc engine.
Outlets and Runtime
Two 120V GFCI 5-20R outlets, an NEMA L14-30R 30A twist lock for transfer switch use, and a 12V DC cigarette lighter outlet. Three outlets is the smallest panel here, so you will be counting loads carefully rather than plugging in freely. The 4 gallon tank gives up to 11 hours at half load, which is a real night-plus-morning of coverage.
Where the Budget Tier Shows
Conventional output means no clean power for electronics, and the 224cc engine is louder under load than the inverter units in the same weight class. At 105.8 pounds with a wheel and handle kit, it is manageable but not a one-person carry. The 2 year warranty is also the shortest in the roundup after the Pulsar.
For Whom It Is Good
It is for a first-time buyer with a small apartment, a condo, or a house where the plan is a refrigerator, a freezer, lights and internet through a shorter outage. The electric key start and the transfer switch ready 30A outlet put it above most entry-level machines.
For Whom It Is Bad
It is not for sensitive electronics, not for a household with central air or a well pump, and not for a three-day outage on stored gasoline alone. The small tank and 4 gallon capacity also mean more refills than the mid-size machines.
12. DuroStar DS13000MX – Remote Start with a 17-Hour Tank
DuroStar DS13000MX 13,000-Watt 500cc Dual Fuel Portable Generator – Gas and Propane, Remote Electric Start, Whole Home Power Backup, Transfer Switch Ready, RV & Emergency Ready
10500 running watts, 13000 total output
8.3 gallon tank, up to 17 hours
Remote electric start with remote control
CO Alert auto shutdown
+ Pros
- 10500 running watts for whole-home backup during storms
- Remote electric start with an included remote control
- 8.3 gallon tank supports the longest gasoline runtime here
- CO Alert auto shutdown for safety
- Transfer switch ready 50A outlet with an all-metal frame
– Cons
- Conventional output is not inverter clean for electronics
- 220 pounds is among the heaviest units here
- Open frame design provides no weather enclosure
- 10 percent of reviews are one-star
The DS13000MX is the specification outlier. Its 8.3 gallon tank is the largest gasoline capacity in this roundup, and the 17 hour runtime figure is the longest gasoline endurance here, which makes it the natural choice for a household that expects a long outage and wants to refill as rarely as possible.
It pairs that with 10500 running watts, a transfer switch ready 50A outlet, remote electric start with an included remote control, and CO Alert automatic shutdown.
Tank Size and Remote Start Combined
Tank size and remote start solve different halves of the same problem. The tank decides how long you can run before doing anything; the remote decides whether starting it requires going outside. A 17 hour tank means a night and most of a second day on gasoline at reduced load, and the front-facing fuel selector means switching to stored propane is a matter of turning a valve.
Reliability and the One-Star Share
About 10 percent of reviews are one-star, which is a higher failure share than the top-rated models here and a genuine reason to hesitate. Owners who are happy value the raw power, the metal construction and the remote start for emergency backup. A minority report reliability and support problems, and that is worth weighing if this is the only machine you plan to own.
For Whom It Is Good
It is for a household that wants maximum output, a large tank, remote start and a 50A connection, and that accepts an open frame machine at 220 pounds in the yard. For a long, unattended outage the fuel capacity is the standout feature.
For Whom It Is Bad
Conventional output rules it out for electronics, and at 220 pounds it is difficult to reposition alone. The one-star share makes it a harder recommendation than the Westinghouse and Champion machines of similar output, and the open frame means it must be sheltered from rain.
Carbon Monoxide Safety: Twenty Feet, Outdoors, Every Time
Consumer safety regulators in the US attribute roughly 90 generator-related carbon monoxide deaths a year to improper use, and almost all of them share one cause: a machine running too close to people. Every rule below comes back to that single number.
The 20-Foot Rule
Run the generator at least 20 feet from the house, with exhaust pointing away from doors, windows and vents. Opening a garage door does not make indoor operation safe, and a machine running in a garage, even with the door up, puts carbon monoxide into a space you breathe. This is the rule people break, and it is the one that kills people.
CO Shutdown Sensors Are Not a Substitute
Most of the machines here carry an automatic CO shutdown: CO Alert on the DuroStar, CO Shield on both Champions, the WEN Watchdog on both WEN inverters, and CO sensor protection on the Westinghouse WGen5300DFcv, the DuroMax and the PowerSmart. A sensor is a backup layer, not permission. It protects against a failure mode, not against a badly placed machine.
Buy a battery CO detector with a digital alarm for every level of the home, and put the generator where a house with a working detector would not matter. A properly ventilated setup for any combustion equipment follows the same logic, and the same discipline applies here.
Fuel Storage Before the Storm
Store gasoline in approved containers, in a ventilated shed or detached garage, away from the house and away from ignition sources, and never in a basement or an attached garage with a combustion appliance. Rotate your fuel supply and use stabilizer, because gelled fuel is as good as no fuel. Propane cylinders store without that problem, which is the practical argument for dual fuel in the first place.
When a Machine Has Been Submerged
If storm surge or floodwater has covered the generator, do not start it. Shut off the fuel, disconnect the battery if it is accessible, and let the unit dry completely before inspection. Salt water in the windings and the ignition system will destroy an otherwise healthy machine, and starting it wet is how a usable generator becomes a scrapyard donation.
How to Size a Dual Fuel Generator for a Hurricane Outage
Sizing a generator is arithmetic with a safety margin, not a guess. Add up the running watts of everything you want on, add the starting watts of the largest single motor load, and then plan to run at no more than 80 percent of rated output continuously. That last rule is the one most people skip and the one that causes the overload trips people complain about on forums.
Running Watts and the 80 Percent Rule
Running watts are what an appliance draws while running. Starting watts, sometimes called surge or peak watts, are what it draws in the first few seconds while a motor spins up. A refrigerator might run at 150 watts and start at 1200. A well pump might run at 1000 and start at 3000. Only the running figure counts toward sustained load, but the starting figure is what trips a breaker.
So if your running total is 6000 watts, a 9500 watt machine gives you 63 percent of rated capacity and comfortable headroom. The same 6000 watts on a 6500 watt machine is 92 percent, which is why owners of mid-size units report the unit “loses power when the fridge and AC compressor kick in at the same time.” That is an overload condition, not a defect.
What a 12000 Watt Class Machine Actually Runs
A 10500 or 12000 watt class machine typically covers a 3 to 5 ton central air conditioner, a refrigerator, a freezer, a well pump, a sump pump, lighting and a router at the same time. That is the standard answer to how big a house a 12000 watt generator will run, and for a 2000 square foot house with central air and a well, that class is the right starting point.
A 5000 watt class machine covers a refrigerator, a freezer, a router, lighting and a small window unit, and most well pumps. A 4000 watt class inverter covers a refrigerator, a freezer, internet, chargers and lights, and possibly one window air conditioner. Anything below that is an essentials-only machine, which plenty of households run happily for a week.
Inverter vs Open Frame
Inverter units use less than 3 percent total harmonic distortion, run in the 52 to 64 dBA range at partial load, and weigh roughly 49 to 105 pounds. Open-frame conventional units offer higher raw output, 120/240V flexibility, 50A transfer switch outlets and larger fuel tanks, at 135 to 234 pounds and 70 dBA or more under load.
For a hurricane, the deciding question is where the machine will sit and what you will plug into it. If it runs overnight near a bedroom, or powers a home server, a medical device or a CPAP machine, inverter wins. If it powers central air and a well pump through an interlock, output and the 30A or 50A connector win, and you manage noise with location and a canopy rather than with the purchase.
Load Sequencing After the Power Goes Out
Start the generator first, with nothing connected. Let it stabilize for a minute. Then connect loads in this order:
First the well pump or sump pump, alone, because it is the highest starting surge on the list. Wait 20 seconds for the engine to settle. Then the refrigerator and freezer. Then a window air conditioner, one at a time. Then lighting, internet and chargers last.
Reverse the order when you shut down. This sequence is the single most useful piece of advice on prep forums, and it eliminates the surge trips that make people believe their generator is undersized when it is not.
Transfer Switch or Interlock Kit
A transfer switch is installed by a licensed electrician and costs more, but it is the only safe way to power house circuits directly. An interlock kit is a simpler device that prevents grid power and generator power from meeting, and it is a legitimate and much cheaper option on many machines. Either one is a far better answer than running extension cords through a window, which is how backfeeding injuries and fires happen.
Check that the connector on the generator matches the device. The L14-30R 30A outlets here, on the Westinghouse WGen9500DF, WEN DF475T, Champion and Pulsar units, are the common residential pattern. The 14-50R and 50A outputs on the Westinghouse and DuroMax units suit full RV and 50A subpanel applications.
Propane Depletion Math for 3 to 7 Days
A 20 lb cylinder holds roughly 5 gallons of propane after the reserve, and a typical 3000 watt dual fuel unit will consume about 3.5 gallons a day at partial load on propane. That is roughly 10 hours per cylinder. A 40 lb cylinder roughly doubles that to about 19 hours, and a 100 lb cylinder runs about 48 hours.
For a 5000 watt class machine, plan on roughly 5.5 gallons a day at partial load, which is close to one 20 lb cylinder a day. For a 9500 watt class machine at high propane output, budget about 8 gallons a day, or a 40 lb cylinder roughly every day and a half.
So for a five-day outage, a small household on a 3000 watt propane load wants five 20 lb cylinders, and a whole-home household on a 9500 watt propane load wants something closer to four 40 lb cylinders. This is the number most households get wrong, and it is why people run out of propane on day two. When we ran these figures against the manufacturer runtimes in this roundup, the gap between a cylinder and a day of running was consistently larger than owners expected. A larger fixed installation with a proper regulator is the upgrade path if you expect to run a big unit for a week.
Our reading of the spec sheets points to a simple rule we use ourselves: if you will sleep next to it, buy the inverter. If the machine will live 30 feet away at the end of a driveway, buy the output.
Noise, Neighbors and Multi-Day Runs
Open-frame units running 70 dBA or more for four days attract complaints, and in some HOAs they attract fines. The published 52 dBA figure on the Westinghouse iGen5000DF, 59 dBA on the PowerSmart and 61 to 64 dBA on the Champions are the numbers to look at if the machine will be close to a wall you share. Distance and a canopy do more than most buyers expect, but they cannot fix a machine that is simply too loud for the position.
Our fuel injector cleaner guide is worth a look if your machine has been sitting with stale gasoline, since carburetor varnish is the leading cause of a generator that will not start after months of disuse.
Frequently Asked Questions
What is the best generator to use during hurricane season?
A dual fuel portable generator is the best choice, because stored propane does not spoil while gasoline does. Our top pick is the Westinghouse WGen9500DF at 9500 running watts on gasoline and 8500 on propane, with remote electric start and a transfer switch ready 30A outlet. Smaller households often do well with a quiet inverter such as the Westinghouse iGen5000DF at 52 dBA.
What is the disadvantage of a dual fuel generator?
Three drawbacks matter most. First, propane output is typically 10 to 15 percent lower than gasoline, so a 9500 watt gasoline rating becomes roughly 8500 watts on propane. Second, propane costs more per hour of run time and depletes faster than the marketing figures suggest. Third, the engine and fuel system are more complex, and a frozen or failed propane regulator can stop a machine that would have run on gasoline alone.
Will a 5000 watt generator run a fridge and freezer?
Yes. A refrigerator typically draws around 150 running watts and 1200 starting watts, and a freezer is similar, so a refrigerator and freezer together run well under 500 watts continuously. A 5000 watt class machine handles that easily with room left for lights, a router, a sump pump and a window air conditioner.
Can I power my well pump with a generator?
Yes, and a well pump is a good reason to size up rather than down. Most submersible well pumps draw roughly 1000 running watts and up to 3000 starting watts, so a 5000 watt class machine can start and run one. Start it first with nothing else connected, let the engine settle for about 20 seconds, then add other loads. A 9500 watt class machine lets you run the well pump and central air at the same time.
Who makes the quietest dual fuel generator?
Among the models reviewed here, the Westinghouse iGen5000DF has the lowest published noise figure at 52 dBA, with the PowerSmart at 59 dBA and the Champion 4500W at 61 dBA. Inverter generators are consistently quieter than open-frame units, which typically exceed 70 dBA under load. Published noise figures are measured at partial load, so expect more noise at full output.
Which Dual Fuel Generator to Buy in 2026
If you run central air, a well pump and a refrigerator, the Westinghouse WGen9500DF is the pick, and its remote start and 30A transfer switch ready outlet are the reason it outranks everything else in this roundup. If your priority is sleeping through the outage rather than cooling the house, the Westinghouse iGen5000DF at 52 dBA and under 3 percent total harmonic distortion changes the whole experience, and it also protects electronics.
If tank size is what worries you most, the DuroStar DS13000MX with an 8.3 gallon tank and 17 hour gasoline runtime minimizes refills, and the Pulsar G12KBN with 8 gallons and a 50A outlet is the balanced version of the same idea. For propane endurance, the Champion 4500W at 21 hours and the PowerSmart 3800W at 24 hours on a 20 lb cylinder are the machines to look at.
For a condo, an apartment or a house with a modest load, the Champion 4000W at 51.8 pounds or the WEN DF360iX at 49 pounds give you clean power you can carry yourself. Whichever you choose, run it 20 feet from the house, buy a CO detector for every level, size your load list against the propane wattage rather than the gasoline wattage, and store more cylinders than you think you need.
