The list in brief
Which pick fits you?
- For RV owners: If you need to power a 30A RV shore connection and want a generator that runs on both gasoline and propane, models with an RV-ready outlet and CO sensor are the safest bet. See pick 7
- For campers and tailgaters: Look for a compact unit under 3000 watts that is easy to lift and store; the A-iPower 2300W is the smallest in this list and can handle lights, a small fridge, and charging devices. See pick 4
- For whole-house backup: If you want to run a well pump, furnace, and some circuits during an outage, a generator with over 5000 watts and a CO sensor, like the Westinghouse 12000, offers the most capacity here. See pick 2
- For basic home use: A simple dual fuel inverter without extra bells, such as the PowerSmart 3800, can keep a refrigerator and lights running; just be aware it lacks a CO sensor and electric start. See pick 12

The specs, compared
Why these made the list
To build this guide, we pulled 12 dual fuel inverter generators from our catalogue, all from established brands, and compared them on the seller's published specifications: fuel type, inverter type, wattage range, RV readiness, carbon monoxide sensor, and electric start. We looked for a mix of power outputs to cover home backup, camping, and RV use. Prices shown are live from the store listing and were read at the time of writing; we did not test any of these units. Our picks are based on stated specs only, not on performance claims or reviews.
Things to weigh before buying
Gasoline vs. propane: what dual fuel means for you
A dual fuel inverter generator runs on either gasoline or propane (LPG). Gasoline is more energy-dense and easier to find, but it degrades over time and can clog the carburetor. Propane has a longer shelf life, burns cleaner, and is often cheaper for camping. Most units switch between the two, so you can choose the fuel that fits your situation. If you plan to store the generator for months, propane is the better choice; if you need maximum runtime, gasoline is typically better. Check the maker's manual for fuel-specific runtime and output, as wattage may drop slightly on propane.
Wattage: match the generator to your loads
The seller's spec gives a wattage range, such as 3000-5000 watts. The low end is the continuous running wattage, the peak is the starting surge. Add up the wattage of everything you want to run simultaneously (refrigerator, lights, phone chargers, etc.) and allow extra for the starting surge of motors like a well pump or air conditioner. A 2000-3000 watt unit is fine for camping and small appliances; 3000-5000 watts covers most home essentials; over 5000 watts can handle heavy loads like a central AC or a whole-house panel, but you'll need a larger, more expensive machine. In this list, the Westinghouse 12000 is the only one rated over 9000 watts.
Carbon monoxide sensors: a must-have for safety
Portable generators produce carbon monoxide (CO), an odorless, colorless gas that can kill in minutes. The CPSC and CDC advise never running a generator indoors, in a garage, or near windows or doors, and always placing it outside at least 20 feet from the home. Many modern units, like the WEN and Westinghouse models in this list, include built-in CO sensors that automatically shut off the generator if dangerous CO levels are detected. When choosing a generator, look for this feature if you plan to use it near living spaces or in an RV. Even with a sensor, you should still follow placement rules and have a battery-powered CO alarm in your home or RV.
RV-ready outlets and parallel capability
If you plan to power an RV, look for a generator with a 30A RV outlet (often labeled 'RV-ready') or a 120V/240V locking receptacle for larger rigs. Some models, like the A-iPower 2300 and several Westinghouse units, include this outlet for direct hookup without an adapter. Parallel ready is another feature: it lets you connect two identical generators to double the power output. If you anticipate needing more power in the future, choose a parallel-ready model. Keep in mind that not every generator offers parallel capability; check the seller's specifications.
Electric start vs. recoil start
Electric start lets you turn on the generator with a button or remote, which is convenient, especially for larger units that are hard to pull. Most electric models, like the WEN 4800 and Westinghouse 4000, also have a battery that requires maintenance. Recoil start (pull rope) is simpler and lighter, but might be tiring on high-compression engines. Some generators offer both. If you have arthritis or back issues, electric start is worth the extra cost. In this list, five models have electric start: the WEN 4800, Westinghouse 12000, WEN 6800, Westinghouse 4000, and Westinghouse 5000.
Runtime and fuel tank size
Runtime on a full tank varies by load and fuel type. The seller's specifications often list runtime at a certain load (e.g., 8 hours at 50% load). Propane typically gives slightly lower runtime than gasoline per gallon, but you can connect larger propane tanks for extended operation. For home backup, a longer runtime means fewer refueling stops. Look for a model with a fuel tank that matches your needs, and consider that you can always store extra fuel containers, but always follow safety guidelines for storing gasoline and propane.
Questions
Can I run a dual fuel inverter generator indoors during a power outage?
No. Never operate any portable generator, including dual fuel inverter models, indoors, in garages, basements, crawlspaces, or sheds. Compare the dual fuel inverter generators to see which models have CO sensors and auto shutoff. Carbon monoxide (CO) can build up to deadly levels in minutes. Always place the generator outside, at least 20 feet from windows, doors, and vents, with the exhaust pointing away. Install battery-operated CO alarms on every level of your home. Even if the generator has a CO sensor, you must still follow these placement rules.
Does using propane instead of gasoline reduce the generator's maximum wattage?
Generally, yes. Propane has a slightly lower energy content by volume than gasoline, so many dual fuel generators see a small reduction in output when running on propane, often around 10%. The seller's specifications may list separate wattage for each fuel. In this list, the wattage range given is the same for both, but always check the owner's manual for specific derating information.
What is the difference between an inverter generator and a conventional generator?
An inverter generator produces cleaner, more stable electricity with lower total harmonic distortion (THD), making it safe for sensitive electronics like laptops and smart TVs. It also runs at variable engine speed to match load, which improves fuel efficiency and reduces noise. Conventional generators run at a fixed engine speed and produce less stable power, which can damage electronics. For dual fuel, inverter models are dominant because of their portability and quietness.
How do I connect a dual fuel generator to my RV?
Most RVs use a 30A or 50A shore power plug. If your generator has an RV-ready outlet (usually a TT-30R for 30A), you can plug an RV power cord directly into it. For 50A RVs, you'll need a 30A-to-50A adapter or a generator with a 14-50R outlet. Always ensure the generator's total wattage covers the RV's loads (air conditioner, microwave, battery charger). In this list, models like the Champion 4000 and Westinghouse 2550 have an RV-ready outlet.
