10 Best Rated Inverter Generators 2025 in the United States

The PowerSmart 4800-Watt Portable Inverter Generator is a versatile and efficient choice for those needing a reliable power source for residential, camping, or emergency use. With a starting wattage of 4800 and a running wattage of 3600, it provides substantial power that is suitable for a variety of appliances and electronics. One of its standout features is the inverter technology, which ensures clean power delivery with less than 3% Total Harmonic Distortion (THD), making it safe for sensitive devices.

Portability is another strength, as this generator weighs just 72 pounds and includes a wheel handle kit, facilitating easy transportation and storage. The noise level is reasonably low, rated at 67 dB during full load and 59 dB at half load from 23 feet away, making it a quiet option for outdoor activities or home use without causing much disturbance.

In terms of runtime, the generator can operate for up to 10 hours at half load, which is adequate for overnight use or extended outdoor events. The inclusion of multiple outlets, including USB ports, enhances its flexibility in powering diverse devices. While it's primarily gas-powered, the generator's fuel efficiency is commendable, although users will need to ensure they have sufficient fuel on hand for longer operations. The built-in CO Sensor adds an essential safety feature, alerting users to potentially dangerous levels of carbon monoxide.

However, the generator is not the lightest in its category, and some users might find maneuvering it over uneven terrain challenging despite its portability. Additionally, it ranks #39 in Outdoor Generators, which suggests that there are more popular options available, possibly with more advanced features or better pricing.

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.
