Most people think of a gas generator as the simplest method to generate backup power in an emergency, but a dual-fuel generator—which can run on gas or propane—provides a more versatile option. When fuel is scarce, having two ways to run your generator gives you more options.
Dual-fuel generators also provide greater control over secondary concerns such as noise and emissions: While gas is readily available at every station, propane burns cleaner and more quietly. The most effective dual-fuel generators not only provide the best of both worlds but also have a range of convenient features to make your user experience simple and safe.
Here are the top 9 best dual fuel generators:

This is the best of the best semi-portable choice we know of if you need a lot of power and the freedom to move your generator around. It’s somewhat larger and nearly twice as hefty as our “best small” pick. Nonetheless, with a similar 3,700-4,500W power, it is substantially more compact and portable than other dual-fuel generators.
That’s enough electricity for a large camping trip, an RV, or a construction site. This is more expensive, but the quiet operation and stylish yet sturdy build quality make it well worth it.

It’s not uncommon for a dual-fuel generator to include an electric start switch—all of the options on this list have one, either alone or in conjunction with a pull cord. The Wen DF1100X distinguishes itself with an automated shut-off system that could conserve electricity in an emergency.
The Wen DF1100X is available in an array of variants. However, we strongly recommend the model with a built-in CO2 shutdown sensor, which is essential if you use the generator in a garage or other poorly ventilated area.
This is a generator powerhouse, with a massive 8,300-11,000W output, above-average gas capacity, and a comparatively low operating volume. It’s both expensive and heavy, but if you want an easy-on, safety-off choice, it’s an excellent purchase.

This Duro Star generator is essentially a smaller, less expensive version of our top overall recommendation. The Duro Star DS 5500 EH gives around half the power of the DuroMax XP 12000 EH for slightly under half the price. A 4,500W generator provides enough of power for charging an RV, recharging power tools at a job site, or keeping critical appliances running during a power outage.
It’s not exactly light at little over 100 pounds, but it’s also not so hefty that you can’t move it. It wouldn’t be too difficult to transport it camping, especially since it has wheels.

When it comes to pure power-to-price ratio, this Champion product performs admirably. It weighs slightly more than 200 pounds and is powered by a 439cc 4-stroke engine. It generates 9,375 starting watts and 7,500 operating watts when powered by gasoline. It produces 8,400 starting watts and 6,750 operating watts on propane.
That’s enough power for even huge jobs or emergency whole-home backup. Despite its size and weight, because to the strong inbuilt wheels, it is rather easy to move around. It readily starts with an electric system, but it also has a recoil option for emergency use.

The DuroMax XP12000EH dual-fuel generator is a true workhorse. It has a continuous output of 9,500W, which is more than enough to power a whole home, and a peak output of 12,000W, which allows it to give more power if a far larger need arises. It also boasts a large 8.3-gallon gas tank, allowing it to run for an extended period of time on just gasoline.
Furthermore, the XP12000EH has a strong reputation for dependability. It was designed for hard use, such as on a construction site, and its all-metal structure assures that it can withstand some roughhousing. But with all that metal and gas capacity, it’s quite heavy. With a weight of 238 pounds, you won’t be moving it around much, and forget about bringing it camping. However, it comes with a wheel kit that may aid with the burden over short distances.

It’s unusual to find a really portable dual-fuel generator, but this little guy from A-iPower delivers excellent output in a surprisingly small package. The A-iPower SUA2000iD, which is roughly the size of two stacked shoeboxes, will easily fit into a van or RV. While 55 pounds isn’t exactly light, it is the lightest dual-fuel generator I’ve come across thus far. It’s also approximately the same volume as an electric toothbrush, so… not that loud.
You won’t get the same power as a full-sized generation (1,600-2,000 watts), but it will keep your small appliances running and your devices charged. Owners have noted that their generators are still functioning well after more than five years, indicating that the construction is of high quality. Again, the tiny size of the gas tank is a benefit in this scenario.

This four-stroke dual fuel generator is ready to use straight away. It can provide nine hours ofcontinuous electricity with a full tank of gas and propane, keeping your home warm, safe, and secure even during an emergency. Touch Start operation powers the strong Champion engine, making this dual fuel generator exceptionally simple and quick to use.
A Volt Guard secures the household outlets, which is designed to safeguard your equipment from electrical surges, making this dual fuel generator extremely safe to use. This dual fuel generator features a powerful engine that can both run and protect your household appliances during a power outage.

This dual-fuel generator weighs only 44 pounds and includes a top handle, making it ideal for portability. It can run on either gasoline or propane, with a simple switch switching between the two fuel options. The fuel tank is modest at 1.18 gallons, which is a trade-off for the smaller and lighter generator. Even with the smaller tank, it can run for up to 8 hours on a single tank of gas.
It features two regular 120V outlets as well as a 15A alternating current outlet. You may also connect two of these generators in series to increase overall power output. Special cables are, of course, required for this. Fortunately, this is one of the more affordable solutions.

This dependable generator costs about half the price of some larger models but includes many of the same features that make operation simple. On the side of the control panel, there is a huge selection dial that clearly reveals whether you have picked gasoline or propane. The 4-gallon gasoline tank allows for up to 11 hours of run time. It can be used in an emergency, but due of its lower overall power output, it’s suited for minor chores like charging gadgets when camping or power tools in the yard.
It does have a key that you must turn in order for it to work. Keep this key in a safe location because the generator will not work without it. It contains a 12V DC outlet, two normal 120V GFCI AC outlets that can accommodate most home equipment and products, and an L14-30R outlet. When not in use, a cover for this generator is recommended to protect the outlets and other exposed parts from dust and debris. Fortunately, WEN produces an affordable cover that fits this model precisely.
