10 Best Generator Inverters 2025 in the United States

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 Westinghouse Outdoor Power Equipment 5000 Peak Watt Super Quiet Portable Inverter Generator is a versatile and powerful option for those needing reliable backup power or portable electricity for travel trailers and home use. With a peak wattage of 5000 watts and a running wattage of 3900 watts, it provides ample power for essential appliances and devices. The gas-powered generator features a generous 3.4-gallon fuel tank, offering up to 18 hours of runtime, which is excellent for extended usage without frequent refueling.

Its inverter technology ensures clean and stable power, making it safe for sensitive electronics. A key highlight is the low noise level, operating as quietly as 52 dBA, which makes it suitable for residential areas and camping trips. The remote electric start with an auto choke and the included key fob adds convenience, while the telescoping handle and wheel kit enhance portability despite its 119-pound weight.

The generator is also RV-ready with multiple outlet options, including a 120V duplex household outlet, an RV-ready 30 Amp outlet, and two USB outlets, adding to its versatility. The LED data center provides useful information like fuel level and remaining runtime, helping with efficient fuel management. The product is backed by a 3-year limited warranty. However, its weight might be a concern for some users, and being gasoline-powered means it requires proper handling and storage of fuel. This generator is ideal for those seeking a robust, quiet, and portable power solution for various applications.

The DuroMax XP13000EH is a powerful dual fuel generator offering up to 13,000 watts of starting power and 10,500 watts running power, making it suitable for whole-home backup during outages or for heavy-duty outdoor use. It runs on both gasoline and propane, which adds flexibility depending on fuel availability. The generator features an electric push-button start and a user-friendly front panel to switch between fuel types quickly.

Built with a sturdy metal frame and no plastic parts, it is designed for durability across various weather conditions and terrain, with no-flat tires for easy mobility despite its heavy 234-pound weight. Although it’s portable, it’s quite large and might be challenging to move without help. The generator includes safety features like low oil shutdown and a CO sensor, enhancing safe operation.

While it doesn’t advertise advanced inverter technology specifically, it delivers stable power with 100% copper windings, which helps extend its lifespan and performance. Given its size and power, it may be louder than smaller inverter models. This generator is ideal for those needing robust, reliable power for entire homes, RVs, or job sites, especially when fuel options and durability are priorities. For users seeking a quieter or lighter generator mainly for sensitive electronics, a smaller inverter-focused model might be more suitable.
