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 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.

The WEN DF452iX is a dual fuel inverter generator that runs on both gasoline and propane, offering flexibility and longer runtimes thanks to its auto fuel selection. It produces 4500 surge watts and 3500 running watts on gasoline, and slightly less on propane, which is a solid power output for running multiple devices or small appliances, making it a good fit for camping, RV trips, or backup home power. The 212cc engine keeps noise levels low at about 58 decibels from 22 feet away, which is relatively quiet for this power range and helps keep your environment peaceful.

Portability is decent with onboard wheels and a carrying handle, though it weighs about 100 pounds, so it’s not the lightest but still manageable for two people. The generator is EPA III and CARB compliant, ensuring it meets emissions standards, and it produces clean power with low total harmonic distortion, which is important for safely powering sensitive electronics like smartphones and laptops. It also features a remote electric start that works from up to 160 feet away, adding convenience, plus safety features like a CO Watchdog carbon monoxide sensor and a fuel shut-off for easier maintenance.

On the downside, the 8-hour runtime is moderate but may require refueling during extended use, and the weight might be a challenge if you need something very portable. Also, while it covers the basics well, those needing very high power output or ultra-lightweight options might look elsewhere. This WEN generator balances power, quiet operation, and versatility, making it a practical choice for RV owners or anyone looking for a reliable, multi-fuel inverter generator.
