10 Best Generator Inverters 2025 in the United States

The DuroMax XP15000HX is a powerful dual-fuel portable generator offering up to 15,000 watts of starting power, which is plenty for running most household appliances during a power outage or on a job site. It runs on either gasoline or propane, giving you flexibility and cleaner, longer-lasting fuel options. This generator is designed for whole-home backup, with multiple outlets including a transfer switch-ready 50 amp outlet, making it easy to connect to your home’s electrical system. It features a strong 670cc engine and copper windings that help ensure durability over time.

The XP15000HX is equipped with user-friendly features like a digital display showing voltage and hours of use, push-button electric start, and a remote control for convenience. Safety is a priority with its built-in CO Alert system that automatically shuts down the generator if harmful carbon monoxide is detected.

Regarding portability, it includes wheels and a handle, but at 345 pounds, it is quite heavy, so moving it around might require some effort or extra help. Generators of this size commonly produce noticeable sound, which may be a consideration if quiet operation is important. While it does not provide pure inverter output, which is ideal for the cleanest power for sensitive electronics, this model offers high wattage, reliable whole-home backup, dual-fuel convenience, and important safety features.

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.

The DuroMax XP11000iH is a powerful dual-fuel portable inverter generator delivering 11,000 peak watts and 9,000 running watts, making it a strong choice for emergency home backup, job sites, or RV camping. Its ability to run on either gasoline or propane adds useful flexibility, especially when fuel availability is uncertain. This model features inverter technology that provides clean, stable power, which is essential for safely running sensitive electronics like computers and TVs. The generator also includes a remote electric start, making it convenient to operate from a distance.

Safety features like CO Alert, which automatically shuts off the unit if carbon monoxide levels get too high, and low oil shutoff help protect both users and the machine. It’s built to handle heavy-duty use with an EPA and CARB-approved engine and supports an automatic transfer switch for easy home connection during power outages. Despite weighing 216 pounds, it’s still labeled portable, although moving it around may require some effort or assistance.

The option to connect two units in parallel for even more power is a handy feature for larger needs, though the parallel kit is sold separately. Backed by a 5-year warranty, this generator suits people needing a high-powered, versatile generator capable of handling multiple uses, from outdoor adventures to home emergencies. The size and weight should be considered if portability is a top priority.
