10 Best Portable Inverter Generators 2025 in the United States

The Westinghouse 11000 Peak Watt Dual Fuel Portable Inverter Generator is a powerful and versatile option for those needing reliable backup power or a portable power source. It offers substantial power output with 11000 peak watts on gasoline and 10000 peak watts on propane, making it suitable for running multiple appliances or heavy-duty equipment. The dual fuel capability provides flexibility, allowing you to choose between gasoline and propane based on availability and preference.

With a 9.8-gallon fuel tank, it can run up to 17 hours, making it suitable for extended use during outages or outdoor activities. Its low THD (less than 3%) ensures safe usage for sensitive electronics, a key advantage for modern households. Portability may be a bit of a challenge due to its 187.4-pound weight, but the inclusion of a remote electric start and transfer switch readiness adds convenience.

The generator also features a CO sensor for added safety, a rotating digital display for easy monitoring, and comes with various accessories for immediate setup. This generator is ideal for residential use, offering robust power, flexibility, and modern safety features, though its weight may be a point to consider.

The Honda 664240 EU2200i is a well-regarded portable inverter generator, offering 2200 watts of maximum power output and 1800 running watts. It is gasoline-powered with a fuel tank capacity of 0.95 gallons, which, combined with Honda's Eco-Throttle System, allows it to run for 4 to 9.6 hours on a single tank depending on the load. This makes it suitable for long-duration use, such as overnight power for camping or backup power at home.

One of its standout features is its quiet operation, producing only 48 to 57 dBA of noise, which is quieter than a normal conversation, making it ideal for noise-sensitive environments like campsites or residential areas. Weighing 46.5 pounds and with a compact design (19"L x 12"W x 21"H), it is highly portable and easy to transport. The generator also boasts Honda's inverter technology, ensuring stable and clean power output that is safe for sensitive electronics.

For those needing more power, the EU2200i offers parallel capability, allowing two units to be connected for a combined output of up to 4400 watts. However, it is important to note that the fuel tank is relatively small, which may require more frequent refueling compared to larger units. Additionally, while the generator's THD (Total Harmonic Distortion) is not explicitly stated, Honda's reputation for reliable and clean power suggests it performs well in this regard.

The Honda EU7000IS is a high-performance inverter generator that provides a robust 7,000-watt starting power and 5,500-watt running power, making it suitable for home backup and outdoor activities like RVing and events. Its electric start feature, combined with the Honda My Generator app and Bluetooth capability, adds to the user’s convenience. The generator is fuel-efficient and impressively quiet, which is a significant advantage for residential use and noise-sensitive environments.

The CO-MINDER system enhances safety by detecting harmful carbon monoxide levels and shutting down the generator if necessary. One of its notable strengths is the 3-year residential warranty, providing peace of mind for long-term use. However, at 270 pounds, portability might be challenging without additional help or a dolly, despite its wheels. The runtime of 6 hours and 30 minutes is decent but may require frequent refueling for prolonged use.

Its performance and advanced features make it a reliable choice for those needing a powerful and quiet inverter generator.
