10 Best Dual Fuel Generator 2026 in the United States

The Westinghouse 13500 Peak Watt Dual Fuel Generator is a strong choice for homeowners needing reliable backup power. With 10,500 running watts on gasoline and 9,500 on propane, it can handle multiple household appliances during outages. Its 9.5-gallon fuel tank offers up to 19 hours of runtime, which means fewer refills and longer operation in emergencies. The generator is powered by a durable 500cc 4-stroke engine with features like automatic low oil and carbon monoxide shutdowns, adding safety and engine protection.

One of its best conveniences is the remote electric start, letting you power it up without leaving your home. It also includes a recoil start as a backup. The unit weighs 230 pounds, which is fairly heavy but typical for this power size; it’s portable enough with some effort but not something you’d move around frequently. Generators of this size tend to be moderately loud, so some sound dampening or placement away from living areas might be needed. The generator offers multiple outlets, including standard household plugs, a transfer switch ready outlet, and an RV-ready outlet, making it versatile for various devices and setups. All outlets have rubber covers for added safety.

The generator comes ready to use right out of the box with included accessories like a battery charger, oil, and tools. Plus, it has useful extras like a fuel gauge, USB port, and an hour meter to track usage. Backed by a 3-year warranty and nationwide support, it is a solid option for those who want peace of mind during power outages. While its weight and size make it less ideal if you need something ultra-portable, and noise levels might require planning for quieter operation, this generator’s power, fuel flexibility, and safety features make it well-suited for home backup use.

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 Generac 12,500 Starting Watt Tri-Fuel Portable Generator is a solid choice if you need reliable power for home backup, job sites, or RV use. Its 9,500 running watts and 12,500 starting watts provide enough power to handle most essential appliances and tools, making it suitable for both emergency situations and work needs. One of its standout features is the tri-fuel capability, allowing you to switch between gasoline, propane, and natural gas, which adds flexibility depending on fuel availability. The 7.5-gallon fuel tank offers up to 9.5 hours of runtime at half load on gasoline, so it can keep running through extended outages or long workdays. Portability is decent for a generator this powerful, thanks to the heavy-duty wheels and steel frame, but at 219 pounds, it’s not something you’ll want to move frequently by yourself.

The electric start with a battery included is a big convenience, eliminating the hassle of manual pull starts. Covered outlets help protect against dust and moisture, and there are three power outlets to connect your equipment, though it doesn’t have an extensive variety of outlet types. Noise level isn’t specifically highlighted, but it’s described as quiet operation, which should be comfortable for most residential or job site environments. Additionally, built-in safety features like a CO sensor and low oil shutdown add peace of mind.

The main drawback is its weight, making it less ideal if you need a very portable option. Also, while it covers basic outlet needs, users requiring specialized connections might find it limited. This generator is well suited for those who want a powerful, durable, and flexible fuel source for backup or work purposes and are comfortable handling its weight.
