A dual fuel generator answers a simple worry: what do you do when gasoline is gone, stale, or impossible to find during an outage? By accepting both gasoline and propane, these inverter models let you keep a camp, a home, or an RV running from whatever fuel you can store safely. The decision is less about brand and more about how many running watts you need, whether you want electric start, and how much noise and carbon monoxide protection you expect from a unit parked close to your living space.
This guide is for RV owners, campers, and homeowners shopping for backup power ahead of winter storms and the 2026 camping season. It compares nine listed models using the facts in their titles: wattage, fuel types, start style, safety features, parallel capability, and noise claims. A single generator rarely does everything, so use the sections below to decide whether you need a compact camp unit or a larger home-backup machine.

How to Choose
Running watts versus peak watts
Listings mix running and starting figures, so read carefully. The BILT HARD 5500W lists 4000W running on gasoline and 3600W on LPG, which shows that propane output is usually lower than gasoline output on the same engine. The Westinghouse listings use peak watts, which describe a short surge rather than what the unit delivers continuously. Add up the running watts of every appliance you plan to power, then add headroom for starting surges from refrigerators, pumps, or an RV air conditioner.
Fuel flexibility and runtime
Dual fuel means gasoline plus propane, while the Westinghouse 8200 adds natural gas for a tri-fuel setup that suits a permanent home connection. Propane stores for years without breaking down, which is the main reason buyers choose these machines. Runtime figures such as 8 hours or 12 hours on some listings depend on load, so use them as a rough guide rather than a promise.
Safety, noise, and clean power
Carbon monoxide sensors and auto shutoff, named on several listings, are worth treating as essential. Never run any generator indoors or near windows. For sensitive electronics, a low total harmonic distortion figure such as under 3% THD indicates cleaner power. Noise claims like under 59 dBA matter at campgrounds where quiet hours are enforced.
Start style, parallel capability, and where budget models cut corners
Electric start saves effort in cold weather, remote start adds convenience, and recoil start keeps cost down. Parallel-ready units can be linked with a matching model to double output. Budget models may cut corners on the quality of included hoses, outlet selection, and fuel gauges, so verify outlet types, such as RV-ready sockets, before buying. Ignore flashy extras and focus on the basics: how many watts you truly need, which fuels you can store, and whether the safety shutoffs are listed. Also consider how often you will move the unit, since weight and handles matter more than a spec sheet suggests once it has to go in and out of a truck bed.
The 9 Best Options
WEN DF360iX 3600-Watt
The DF360iX is a quiet, lightweight 3600-watt dual fuel inverter generator listed as RV-ready, with a fuel shut off and a CO Watchdog. It targets campers and small RV owners who want enough power for lights, fans, a microwave, and device chargers without lugging around a heavy unit, and the fuel shut off helps with storage between trips.
- CO Watchdog adds a safety layer for camp use.
- RV-ready outlet and lightweight billing suit travel.
- Trade-off: 3600 watts will not run a large air conditioner plus other loads.
Skip it if you need whole-home backup power or plan to run several big appliances at once.
WEN DF680iX 6800-Watt
This 6800-watt dual fuel inverter with electric start is the largest WEN here, and its listing mentions electric vehicle backup. It fits homeowners who want to run several large appliances during an outage or support a big RV, since the higher rating leaves room for pumps, a refrigerator, and lighting circuits to share the load.
- High 6800-watt rating for larger loads.
- Electric start with fuel shut off and CO Watchdog.
- Trade-off: more power usually means a heavier, bulkier machine.
Skip it if you only need to charge phones and run a few lights, because a smaller unit would be easier to carry.
BILT HARD 5500W
BILT HARD lists 5500W with 4000W running on gasoline and 3600W on LPG, a 160cc OHV engine, CO auto-shutoff, eco mode, and parallel capability. The transparent running figures make planning easier than peak-only listings, because you can match appliance loads to the number for the fuel you will actually burn.
- Clear running-watt figures for each fuel.
- Eco mode and parallel option add flexibility.
- Trade-off: LPG output is lower than gasoline output.
Skip it if you need the maximum possible output while running only on propane.
PowerSmart 3800 Watt
PowerSmart markets this 3800-watt dual fuel inverter for camping or home use, with 8 hours of run time, noise under 59 dBA, CO protection, under 3% THD clean power, and parallel capability. That mix of quiet operation and clean power suits campers with laptops, cameras, and medical devices that benefit from stable electricity.
- Under 59 dBA noise claim suits campgrounds.
- Clean power under 3% THD helps protect electronics.
- Trade-off: 3800 watts limits large appliance combinations.
Skip it if you want electric start, which the title does not mention, or need serious RV air conditioning capacity.
WEN DF480iX 4800-Watt
The DF480iX steps up from the 3600-watt WEN with 4800 watts, electric start, RV-ready outlets, a fuel shut off, and a CO Watchdog. It is a middle choice for owners of mid-size RVs who want more headroom than the smallest unit offers without jumping to the largest and heaviest generator in the family.
- Electric start eases cold-weather use.
- More headroom than the 3600-watt WEN.
- Trade-off: heavier and less portable than smaller units.
Skip it if portability matters more than output, or if you simply need a quiet charging source.
BILT HARD 4500W
This 4500W dual fuel generator offers gas and propane operation, a CO sensor, RV-ready outlets, parallel capability, and a 4-cycle engine. It is a sensible mid-range option for people who might add a second unit later, and the fuel flexibility gives buyers a fallback when one fuel runs short during a long stay.
- Parallel capable for future expansion.
- CO sensor and RV-ready design.
- Trade-off: the title does not state running watts for each fuel.
Skip it if you want listed noise, runtime, or electric start details before you buy.
Westinghouse 8200 Tri-Fuel
This 8200 peak watt inverter runs on gas, propane, or natural gas, with remote electric start, transfer switch readiness, and low THD. It suits homeowners who want the option of a permanent natural gas hookup for outages, with gasoline and propane as backups when the utility line is unavailable.
- Three fuel options, including natural gas.
- Transfer switch ready and remote start.
- Trade-off: the rating is a peak figure, not continuous output.
Skip it if you only camp and have no use for natural gas or a transfer switch.
Westinghouse 5000 Dual Fuel
The 5000 peak watt model advertises a super quiet design, remote electric start, gas and propane operation, an RV-ready build, a CO sensor, and parallel capability. Remote start is the highlight, letting you fire it up from inside the camper or the house on a cold, wet night.
- Remote electric start for convenience.
- Super quiet billing with a CO sensor.
- Trade-off: peak watts do not state continuous output.
Skip it if you want a stated continuous wattage or prefer a simple pull cord.
Champion 4000-Watt
The Champion lists 4000 watts, dual fuel operation, an RV-ready build, an included LPG hose, recoil start, parallel readiness, and quiet technology. It is a straightforward choice for campers who accept a pull cord in exchange for a simpler machine, and the included propane hose means one less accessory to buy.
- LPG hose included for propane use.
- Parallel ready with quiet technology.
- Trade-off: recoil start takes more effort than electric start.
Skip it if you want push-button or remote starting for cold mornings.
Which One Fits Your Situation
You camp with a small trailer
The WEN DF360iX or the PowerSmart 3800 Watt covers lights, fans, and chargers while staying portable and quiet. The PowerSmart lists a noise figure under 59 dBA, which helps near neighbors, while the WEN adds a CO Watchdog and RV-ready outlet for travel trailers.
You want whole-home outage backup
The WEN DF680iX or the Westinghouse 8200 Tri-Fuel has the highest listed output and, for the Westinghouse, natural gas support. Pair either one with a proper transfer switch or inlet installed by a licensed electrician so you never backfeed the grid.
You like starting from a distance
The Westinghouse 5000 Dual Fuel offers remote electric start, which helps in cold or wet weather. Pressing a button indoors beats standing in a storm with a pull cord, especially if the generator sits well away from the house for safety.
You may add more power later
The BILT HARD 4500W and the Champion 4000-Watt are both parallel capable, so a second matching unit can double output. Buy the second unit from the same model line and confirm the parallel kit is compatible before ordering.
Common Mistakes
- Sizing by peak watts instead of running watts.
- Running a generator in a garage or near an open window.
- Forgetting that propane output is lower than gasoline output.
- Ignoring noise rules at campgrounds before buying.
- Storing gasoline untreated for months while the propane option goes unused.

Frequently Asked Questions
Why is propane output lower than gasoline output?
The same engine typically produces fewer watts on propane than on gasoline. The BILT HARD 5500W listing shows the gap clearly, with 4000W on gas and 3600W on LPG.
Do I need an inverter generator?
For laptops, phones, and modern appliances, an inverter model gives cleaner power and tends to run quieter. The under 3% THD claims suggest suitability for electronics.
What does RV-ready mean?
It generally refers to an outlet that matches an RV power cord. Confirm outlet type and amperage with your RV manual before buying.
Is parallel capability worth paying for?
If you may need more power later, yes. Linking two matching units can double output without buying a single large generator now.
