10 Best Quiet Generators 2025 in the United States

The Westinghouse 12500 Watt Dual Fuel Generator is a solid choice for those looking for a powerful and versatile backup power solution. With running watts of 9500 on gasoline and 8500 on propane, plus peak outputs of 12500 and 11200 respectively, this generator can handle most home appliances during outages. Its dual fuel capability adds flexibility, allowing users to switch between gasoline and propane based on availability or preference.

The generator offers an impressive run time of up to 12 hours on a full tank, which is beneficial for prolonged use without the need for frequent refueling. Portability is decent, as it weighs 210 pounds; while it may not be the lightest generator, it does have built-in handles that assist with moving it around.

On the downside, its weight could make it difficult for some users to transport without help, particularly if you need to move it across a yard or to different locations. Additionally, being a gas-powered generator, it may not be the best fit for those seeking an ultra-quiet option for camping or in highly noise-sensitive areas. The safety features, including rubber covers for the outlets and automatic low oil shutdown, add peace of mind during operation.

The Westinghouse 11000 Peak Watt Dual Fuel Portable Inverter Generator offers considerable power output with 9000 running watts and 11000 peak watts on gasoline, and slightly less on propane. This makes it a strong candidate for powering a variety of household appliances and electronics, especially given its low total harmonic distortion (THD) of less than 3%, which is safe for sensitive devices.

The dual-fuel capability (gasoline and propane) provides flexibility, and its large 9.8-gallon fuel tank allows for an impressive run time of up to 17 hours on gasoline. This generator is also equipped with inverter technology, ensuring stable and clean power output, ideal for electronics. At 187.4 pounds, it is quite heavy, which might affect its portability despite its 'portable' tag.

The inclusion of a remote electric start, multiple outlets with rubber covers, and a CO sensor adds to the convenience and safety. The LED data center, displaying crucial information like fuel level and run time, is a useful feature. This generator would be suitable for residential users needing reliable, high-capacity backup power, though its weight might pose challenges for frequent movement.

The Generac 18,000-Watt Gas-Powered Portable Generator offers significant power, making it an excellent choice for emergencies, home use, and recreational activities. It features a powerful 816cc engine that ensures efficient performance. A standout safety feature is the COsense Technology, which provides protection against hazardous carbon monoxide, an essential aspect for user safety.

The TruePower Technology is beneficial for safely powering sensitive electronics, with less than 5% Total Harmonic Distortion (THD), making it suitable for residential use. The generator also includes a low-oil pressure shutdown for enhanced engine protection, which contributes to its longevity and reliability.

Additionally, its large fuel tank extends run times, which is great for long-term use without frequent refueling. However, the generator weighs a hefty 442.8 pounds, which may impact its portability, despite being listed as a portable model. This weight might make it challenging to move around without assistance. This generator is best suited for those who need substantial power and advanced safety features, and don't mind the potential noise and weight.
