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 WEN 11,000-Watt Dual Fuel Portable Generator offers robust power output suitable for a variety of applications, including residential use and camping. With the ability to switch between gasoline and propane, it provides flexibility depending on fuel availability. When using gasoline, it delivers 11,000 surge watts and 8,300 running watts, while propane offers 9,500 surge watts and 7,500 running watts. This makes it capable of powering multiple devices and handling significant loads, which is crucial for emergency backup or powering appliances at a campsite.

Additionally, its 6.6-gallon tank ensures up to 8.5 hours of runtime at half load, which is quite efficient for a generator of this size. The electric start is a convenient feature, simplifying the start-up process, especially in emergencies. The comprehensive range of outlets, including four 120V GFCI outlets, a 120V 30A twist lock outlet, a 120V/240V 50A outlet, and a 12V DC plug, ensures compatibility with various devices and tools.

At 214 pounds, portability might be a concern despite the included wheel kit. It might require extra effort to move around, especially on uneven terrain. The generator's dimensions are relatively compact for its power capacity, but its weight can still pose a challenge. This generator is ideal for users needing a reliable power source for home backup, camping, or any situation that demands a portable and flexible fuel option.

The ERAYAK 4500W Dual-Fuel Portable Inverter Generator is a versatile choice for home backup, RV camping, and outdoor use. It supports both gasoline and propane, providing flexibility and longer runtime — about 16 hours on gas at a quarter load and over 20 hours when using propane. This allows power to last through the night without frequent refueling. With a peak power of 4500W and running power of 3500W on gas, it can handle most household essentials and RV appliances safely thanks to its clean power output (pure sine wave). It features several useful outlets including two 120V outlets, a 30A RV outlet, and USB ports, covering a wide range of devices.

Weighing just 54 pounds and compact in size, this generator is easier to carry and store than many other models, making it suitable for camping or moving around a job site. Its noise level is reasonably low at 58 dBA, so it won’t be too disruptive during use. The starting mechanism is a recoil start, which is simple but may require some effort compared to electric start models. Safety is enhanced by a built-in carbon monoxide sensor that can automatically shut down the generator if dangerous levels are detected. Additional perks include automatic fuel switching when gasoline runs out and electronic speed control to save fuel.

This generator provides a strong balance of power, portability, and safety features, making it well-suited for users who need reliable, flexible fuel options in a compact package. However, the lack of an electric start might be a downside for those wanting quick and easy startup, and while it’s fairly quiet, it’s not the quietest model available.
