10 Best Rated Inverter Generators 2025 in the United States

The Westinghouse 28000 Peak Watt Home Backup Portable Generator is a powerful and feature-rich choice for home backup power needs. With a high power output of 28,000 peak watts and 20,000 running watts, it can handle substantial electrical loads, making it suitable for larger homes or small businesses during power outages. Its 17-gallon fuel tank offers up to 11 hours of runtime at 50% load, ensuring extended operation without frequent refueling.

The generator has a remote electric start with auto choke, which simplifies the startup process, and multiple outlet options, including GFCI-protected and transfer switch ready outlets, offer versatility and safety in powering various devices and systems. It also includes a CO sensor for enhanced safety, automatically shutting down the generator if dangerous carbon monoxide levels are detected. The heavy-duty 999cc Westinghouse V-Twin OHV engine ensures reliable performance, and the digital readout provides important operational information at a glance.

However, at 599 pounds, this generator is quite heavy, which may limit its portability despite the reinforced steel handles. It also has a relatively high noise level, which might be a drawback for residential use in noise-sensitive areas. Another potential downside is the Total Harmonic Distortion (THD) level, which isn't specified, and could impact sensitive electronics. The generator is EPA compliant and comes with a 3-year limited warranty, making it a dependable option for those needing substantial and reliable backup power.

The Honda EU7000IS inverter generator offers a powerful solution with a 7,000-watt starting output and 5,500-watt running output, making it suitable for home backup power, RVs, and outdoor events. This generator stands out for its quiet operation and fuel efficiency, promising a runtime of around 6 hours and 30 minutes. Its electric start feature adds convenience, while the Honda My Generator app with Bluetooth capability allows for remote monitoring and control.

Additionally, the advanced CO-MINDER system enhances safety by detecting carbon monoxide levels. The generator is backed by a 3-year residential warranty, ensuring reliability and peace of mind for users. However, the unit is quite heavy at 270 pounds, which may impact its portability despite its portable design. It's fuel-powered, which might not appeal to those looking for more eco-friendly options.

With a noise level that may still be noticeable in very quiet environments, it might not be ideal for all outdoor settings. The Honda EU7000IS is a solid choice for those needing a robust and reliable power source, particularly for home backup and outdoor use, as long as portability and noise are not major concerns.

The Westinghouse 8200 Peak Watt Tri-Fuel Portable Inverter Generator is a strong choice for those needing reliable home backup power or a versatile generator for camping and work. It delivers a solid 6600 running watts and 8200 peak watts on gasoline, with slightly less power on propane and natural gas, offering flexible fuel options that can save money and extend run time. Speaking of runtime, it can run up to 17 hours on a single 3.9-gallon tank at 25% load, which is quite good for extended use. Thanks to its inverter technology, it adjusts engine speed to your power needs, cutting fuel use and noise — at about 60 decibels at low load, it’s quieter than many traditional generators. The low Total Harmonic Distortion (THD) of under 3% means it’s safe for sensitive electronics like phones and laptops, which is a big plus for home use or job sites.

Portability is decent but not ideal for frequent moves; weighing 134.5 pounds and equipped with flat-free tires, it’s manageable but could be heavy for some users. The electric and remote start make it easy to operate, and safety features like a CO sensor and automatic low oil shutdown add peace of mind. Its 50-amp outlet supports running multiple household appliances simultaneously, including air conditioners and refrigerators, making it well-suited for emergency home power. Some downsides include its weight and size, which may challenge portability, and a price point that tends to be higher than smaller single-fuel generators. For those seeking a flexible, fuel-efficient generator that’s gentle on sensitive electronics and built for backup power, this Westinghouse model is a solid pick.
