10 Best Dual Fuel Portable Generator 2026 in the United States

The Westinghouse Outdoor Power Equipment 12500 Peak Watt Dual Fuel Generator stands out as a robust option for those in need of a reliable power source for home backup, outdoor events, or job sites. With a power output of 9500 running watts and 12500 peak watts when running on gasoline, and slightly lower outputs with propane, it provides ample electricity for most household needs. Its dual-fuel capability is a significant advantage, allowing users to choose between gasoline and propane depending on availability and preference.

Portability is enhanced by its design, though it does weigh 226 pounds, which might be a consideration for some users when transporting it. The generator features a remote electric start, adding convenience, especially in emergencies. Additionally, the inclusion of multiple outlets—including GFCI household receptacles and an RV-ready outlet—provides flexibility in connectivity for various devices.

One of the key strengths of this model is its runtime, with up to 12 hours of operation on a full 6.6-gallon tank, making it suitable for prolonged use. The weight, while providing stability, might limit its portability for some users. Additionally, although it is packed with features such as automatic shutoff for low oil and carbon monoxide detection, these can add complexity for those who prefer a straightforward operation. The generator's size may also be a consideration for storage.

The Westinghouse 13500 Peak Watt Dual Fuel Portable Generator is a strong choice for anyone needing reliable home backup power with flexibility. It offers substantial power, delivering 13,500 watts peak on gasoline and 12,500 on propane, which is enough for most household essentials and some heavy-duty tools. The dual-fuel capability is a big plus because it lets you switch between gas and propane based on what’s available or preferred. With a large 9.5-gallon tank, the generator can run up to 19 hours on gas, making it suitable for extended outages. Starting is easy thanks to the remote electric start feature, plus you have a recoil backup if needed. It includes useful outlets—a couple of standard 120V plugs, a transfer switch-ready connection for home integration, and an RV outlet—covering a variety of needs safely with protective rubber covers.

The generator weighs 230 pounds and is fairly large, so moving it around may require assistance. Safety features like an automatic low oil and carbon monoxide shutdown add peace of mind for home use. The package comes with everything needed to get started, including a battery charger, oil, and tools, which is convenient. This generator is well suited for homeowners wanting a high-output, versatile backup power source who are comfortable managing its weight and typical noise levels for this class.

The WEN 8000-Watt Dual Fuel Portable Generator offers a strong and flexible power solution with its ability to run on both gasoline and propane. It delivers 8000 starting watts and 6500 running watts on gas, and slightly less on propane, which suits many residential and some commercial power needs, like running appliances, tools, or RV essentials. The electric start feature makes it easy to use, especially compared to pull-start generators. With a 6.7-gallon gas tank, you can expect up to 10.5 hours of runtime at half load, so it can keep powering devices through long work sessions or outages.

The CO Watchdog sensor adds a valuable safety layer by automatically shutting down the generator if dangerous carbon monoxide levels build up. Portability is decent with included wheels, though at about 150 pounds, it’s still somewhat heavy to move around frequently. The generator includes a good variety of outlets — four standard 120V outlets, an RV-ready 30-amp outlet, a transfer-switch outlet for home backup, and a 12V DC outlet — making it versatile for different devices and setups.

This generator is a solid choice if you want a reliable, dual-fuel unit with user-friendly electric start and safety features. It is best suited for homeowners, RV users, or light commercial use where moderate portability and runtime are important.
