10 Best Generator Inverters 2025 in the United States

The WEN Quiet 6800-Watt Dual Fuel Inverter Generator is a solid choice for anyone needing dependable power on the go, especially for RV travel or electric vehicle charging. It offers a strong power output with 6800 surge watts on gasoline and 6000 on propane, which covers most small to medium appliances and tools well. Being dual-fuel means you can switch between gasoline and propane, adding flexibility if one fuel type isn’t available. The 224cc engine and 6-hour runtime on a 2.9-gallon tank give a decent balance between power and fuel efficiency, though longer runtimes might require refueling for extended use.

Portability is decent with onboard wheels and a telescoping handle, but the generator’s weight of about 108 pounds means it’s heavier than smaller models, so it suits users who can manage moving somewhat bulky equipment. The built-in WEN Watchdog CO sensor adds an important safety feature by automatically shutting off the generator if carbon monoxide is detected, which is great for peace of mind during enclosed or semi-enclosed use. WEN generators are designed to operate quietly, fitting the 'quiet' label in the name. It includes multiple outlets, such as a 240V outlet for Level 2 EV charging, USB ports, and RV-ready connectors, making it versatile for different devices.

Electric start and fuel shutoff features enhance user convenience and help extend the generator's life. The unit’s weight and size are larger compared to more compact inverter-only models, which might be a consideration for some users. This generator fits well for users needing reliable, reasonably portable power with dual-fuel flexibility and safety features, especially RV owners or those wanting backup power for various electronics.

The WEN 3800-Watt Inverter Generator is a solid choice for those needing reliable power for camping or RV use. With a powerful 212cc 4-stroke engine, it generates 3800 surge watts and 3400 running watts, making it suitable for powering various appliances and electronics. Its inverter technology ensures clean power output, safeguarding sensitive devices like smartphones and laptops. One of its standout features is its quiet operation, which is a significant advantage for users who prioritize a peaceful environment.

The generator's design is also quite user-friendly, with an electric start for easy operation and a range of outlets, including standard 120V receptacles, an RV-ready NEMA TT-30R outlet, and USB ports for versatile connectivity. Its fuel shut-off feature helps maximize the generator's lifespan by using up remaining fuel before shutting it down.

In terms of portability, the generator weighs 99.2 pounds, which might be heavy for some to transport easily, but it remains manageable with wheels or assistance. Its 8.5-hour runtime with a moderate load is decent, though users planning for extended use may need extra fuel on hand. However, the generator's fuel capacity of 2.2 gallons may limit those who require longer continuous operation without refueling. The WEN 3800-Watt Inverter Generator is a versatile and efficient tool for outdoor and emergency power needs, especially for campers and RV enthusiasts, though some may find its weight and fuel capacity slightly challenging for prolonged use.

The Westinghouse 11000 Peak Watt Dual Fuel Portable Inverter Generator is a powerful option for those needing reliable energy, whether for residential use or outdoor activities. With a running wattage of 9000 watts on gasoline and 8100 watts on propane, it provides ample power for various applications. A standout feature is its impressive runtime of up to 17 hours on a single 9.8-gallon fuel tank, making it ideal for extended use without frequent refueling. Additionally, the remote electric start offers convenience, allowing users to start the generator from a distance.

Portability is another strong point, although weighing 187.4 pounds, it may require some effort to move around. The inclusion of multiple outlets, including transfer switch ready options, makes it versatile for different power needs, while the low total harmonic distortion (THD) means it's safe for sensitive electronics.

One potential drawback is the noise level; while it’s quieter than many traditional generators, it's still worth considering if you're sensitive to sound. The generator's weight might also be a concern for some users looking for something lightweight and easily transportable. Additionally, the initial setup, although described as plug-and-play, may still be slightly daunting for those unfamiliar with generator operations. Lastly, the CO sensor ensures added safety by alerting you to dangerous carbon monoxide levels, which is a significant plus for peace of mind.
