10 Best Dual Fuel Generator 2025 in the United States

The DuroMax XP12000HX is a strong choice if you need a powerful dual-fuel generator capable of running an entire home or a commercial space during outages. With 12,000 starting watts and 9,500 running watts, it delivers plenty of power for multiple appliances and heavy equipment. Its ability to switch between gasoline and propane adds flexibility and convenience, as propane burns cleaner and has a longer shelf life. The 8.3-gallon gas tank offers a decent runtime, though exact hours depend on the load and fuel type.

This generator weighs 222 pounds, which is on the heavier side but includes a wheel and handle kit to help move it around. A major convenience is the electric push-button start, eliminating the hassle of pull cords. In terms of connections, it offers a variety of outlets including household 120V sockets, a 30AMP twist-lock, and a 50AMP outlet ready for transfer switches—useful for whole-home power setups. It also features copper windings for durability and a built-in CO Alert for safety.

Noise level specifics aren’t detailed but large generators like this are typically loud, so consider placement accordingly. While it's bulky and somewhat heavy, the foldable handles and wheels ease transport. This model suits homeowners who want reliable backup power, RV users, or small commercial operators needing heavy-duty performance with flexible fuel options.

The Westinghouse 14500 Peak Watt Dual Fuel Generator is a strong choice for homeowners needing a reliable backup power source, especially for larger homes or extended outages. It delivers a powerful 14,500 peak watts on gasoline and 13,500 on propane, which is enough to run multiple appliances or essential home systems simultaneously. The large 9.5-gallon gas tank allows it to run up to 19 hours on gasoline, which is excellent for longer use, although propane runtime is shorter at around 7 hours with a standard 20-pound tank. This generator offers fuel flexibility, allowing you to switch between gas and propane based on availability or preference.

For starting, it includes a convenient electric start with remote key fob, making it easy to operate without manual effort. It also features automatic voltage regulation and safety components like a CO sensor and overload protection, which help keep your devices safe and the generator running smoothly. On the downside, it weighs 230 pounds, so it's not very portable; you’d likely need wheels or assistance to move it around. Larger generators like this are usually louder, so it might not be ideal for quiet neighborhoods.

It offers two power outlets at 240 volts, suitable for home use but might require additional connections for more devices. If you want a durable, high-capacity generator that can run on two types of fuel and start easily, this Westinghouse model is a solid pick, though it’s better suited for stationary use due to its weight.

The DuroMax XP9500iH Dual Fuel Portable Generator delivers robust performance with 9,500 watts peak and 7,600 watts running power, making it suitable for emergency home power, jobsite use, or RV camping. The dual fuel capability allows it to run on both gasoline and propane, offering flexibility in fuel choice. The inclusion of inverter technology ensures clean and stable power for sensitive electronics, which is a significant advantage for homes and workplaces alike.

The remote electric start and automatic transfer switch readiness add to its convenience and ease of use. Additionally, the CO Alert feature enhances safety by shutting down the generator if unsafe carbon monoxide levels are detected. The low oil shutoff further protects the engine, while the parallel capability allows for increased power output when needed.

However, the generator is quite heavy at 216 pounds, which may pose challenges in portability despite being marketed as portable. The noise level isn't specified, but considering the power output, it might be on the louder side. With only two power outlets, it may limit connectivity options for multiple devices. These aspects are worth considering depending on your specific needs. Nonetheless, the generator complies with EPA and CARB standards, ensuring it's environmentally friendly. The DuroMax XP9500iH is a powerful and versatile generator suited for a variety of applications, though its weight and limited outlets might be drawbacks for some users.
