10 Best Dual Fuel Generator 2025 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 DuroMax XP13000HX Dual Fuel Portable Generator is designed to provide robust power with its impressive 13,000-watt output, making it suitable for keeping a whole household running during a power outage. One of its key strengths is the dual-fuel capability, allowing it to run on either gasoline or propane. Propane is a beneficial option as it is cost-effective, clean-burning, and has a longer shelf life compared to gasoline. The generator's 500cc OHV engine and all copper windings contribute to its durability and longevity.

It also offers a wide variety of outlets, including a 50-amp outlet that is transfer switch ready, which is excellent for connecting directly to a home’s electrical system during emergencies. Additionally, the electric start and digital display enhance user convenience. On the downside, the generator is quite heavy at 245 pounds, which may affect portability despite the included wheel and handle kit.

Additionally, the fuel tank capacity of 0.5 gallons may require frequent refueling when running on gasoline, which could be a hassle during longer outages. However, with features like CO Alert for safety and the flexibility of fuel choice, the DuroMax XP13000HX is a strong contender for those seeking a reliable and powerful generator for residential use.

The Generac iQ5200 is a versatile dual-fuel generator that offers up to 5,200 starting watts and 3,900 running watts, making it suitable for home backup and outdoor activities like camping or tailgating. Its ability to run on either gasoline or propane adds flexibility, and the easy fuel-switching feature helps keep it running smoothly without interruption. Weighing 107 pounds and measuring about 3 feet long, it's more compact and portable than many generators with similar power, though it’s still a bit heavy for frequent moving.

One of its standout features is the electric start, which means no more pulling cords—just push a button to get it going. The generator runs quietly thanks to its fully enclosed design, so it won’t disturb your peace during outdoor use or emergencies. It also includes helpful safety tech like COsense, which detects dangerous carbon monoxide levels and automatically shuts the unit off if needed. For connectivity, it offers two USB ports for charging small devices and standard 120V outlets, along with the option to connect a second unit for more power.

Some users might find the 107-pound weight a bit challenging to transport, and while the noise is lower than traditional generators, it’s not completely silent. The Generac iQ5200 provides reliable, clean power with flexible fuel options and easy startup, making it a strong option for camping, home use, or emergency backup.
