10 Best Dual Fuel Portable Generator 2026 in the United States

The Westinghouse 14500 Peak Watt Dual Fuel Portable Generator is a strong choice for homeowners needing a reliable backup power source, especially for larger houses. It offers a high power output—up to 14,500 peak watts on gasoline and 13,500 on propane—which means it can run many household appliances and tools simultaneously. Its dual-fuel capability (gasoline or propane) adds flexibility, useful if one fuel runs out or is unavailable. The 9.5-gallon gas tank supports a long runtime of up to 19 hours at a stretch, while a standard 20 lb. propane tank lasts around 7 hours, so it can keep your home powered for extended outages.

Starting the generator is easy with the electric remote start, sparing you from dealing with pull cords. It includes safety and convenience features like automatic voltage regulation to protect your devices, a CO sensor for safety, and overload protection. Two power outlets provide enough connections for most home setups. However, at 230 pounds, it’s quite heavy, so while it’s portable, moving it might require wheels or extra help.

The durable 550cc engine with a cast iron sleeve promises reliability and longevity. It’s transfer switch ready, making it easier to connect to your home’s electrical system. This generator is well suited for homeowners who want a dependable, high-power dual-fuel unit with easy electric start and long runtime. Its weight and the sound it produces might be considerations if you plan to move it frequently or need something very quiet.

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.

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 generator's size may also be a consideration for storage.
