10 Best Dual Fuel Generator 2026 in the United States

The Westinghouse 12500 Peak Watt Dual Fuel Generator offers strong power output, with 9500 running watts on gasoline and slightly less on propane, making it well-suited for home backup during outages. Its 6.6-gallon fuel tank provides up to 12 hours of runtime, which is practical for extended use. Being dual fuel (gasoline and propane) adds flexibility depending on fuel availability. It includes a remote electric start with a key fob, which is convenient, plus a recoil start as backup.

The generator features multiple outlets, including household standard plugs, a transfer switch ready outlet, and an RV-ready outlet, covering a broad range of common needs. Safety features like a CO sensor and automatic low oil shutdown enhance peace of mind. At about 225 pounds, it is quite heavy, so while it has a front handle, it might be challenging to move frequently without assistance. Noise is rated around 74 dB, which is noticeable but typical for this power size and may require consideration if you need something quieter.

Additional useful features include a fuel gauge, USB port, hour meter, and accessories such as an LPG regulator and battery charger. This generator is a solid choice for homeowners needing dependable, flexible power for backup or outdoor use, though its weight and noise may be less ideal for those prioritizing portability or quiet operation.

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.

The WEN Quiet 6800-Watt Dual Fuel Generator is a solid choice for those needing reliable power during camping, RV travel, or emergency backup. It offers strong power output with 6800 surge watts and 5100 running watts on gasoline, and slightly lower but still substantial power on propane. This dual-fuel capability adds flexibility, allowing users to switch between gasoline and propane depending on availability or preference. The runtime of about 6 hours on a full tank provides decent usage time, though some might find it a bit short for longer use without refueling.

Portability is enhanced by onboard wheels and a telescoping handle, but at nearly 108 pounds, it might be a bit heavy to move frequently by one person. Starting is user-friendly thanks to the electric start system, which avoids the hassle of pull cords. The generator is also RV-ready with multiple outlets, including 120V/240V and USB ports, catering well to a variety of devices and electric vehicle charging needs.

A standout safety feature is the CO Watchdog sensor that automatically shuts off the generator if dangerous carbon monoxide levels are detected, providing peace of mind. Noise levels are described as quiet, which is important for camping or residential use. The generator balances power, safety, and convenience, making it suitable for recreational and emergency use.
