10 Best Quietest Generators 2026 in the United States

The Generac 18,000-Watt Gas-Powered Portable Generator is a robust option for those needing substantial power output. With an impressive 18,000 watts from its 816cc EFI engine, it is well-suited for emergencies, recreational use, and home backup power.

One of its standout features is the COsense Technology, which offers essential safety by protecting against carbon monoxide. Additionally, TruePower Technology ensures that sensitive electronics and tools can be safely powered, thanks to its low total harmonic distortion (THD) of less than 5%.

This generator also includes a low-oil pressure shutdown feature, which helps prevent engine damage and enhances its longevity. Its large fuel capacity allows for extended runtimes, making it durable for long-term use. However, at 442.8 pounds, it is quite heavy, which could impact its portability despite being labeled as portable. This weight makes it less ideal for frequent transport. The generator runs on gasoline, which is readily available but may not be as convenient as other fuel types like propane.

The Honda EU2200i 2200 Watt Portable Inverter Generator is an excellent choice for those needing quiet, reliable power for various settings such as home use, camping, or job sites. With a noise level of 48 to 57 dBA, it operates more quietly than a normal conversation, making it ideal for noise-sensitive environments. The power output is substantial, with 2200 watts at peak and 1800 running watts, sufficient to run multiple appliances. This generator uses gasoline, which is widely available and easy to refuel. Its compact size (19 x 12 x 21 inches) and light weight (46.5 pounds) enhance its portability, making it convenient to transport and store.

The inclusion of inverter technology ensures stable and clean power, safe for sensitive electronics, and the Eco-Throttle system provides impressive fuel efficiency, running up to 9.6 hours on a single tank depending on the load. Additionally, the option to parallel another EU2200i unit for doubled power output adds to its versatility. However, the relatively small fuel tank of 0.95 gallons may require more frequent refueling for extended use. Also, while it excels in multiple areas, the price point might be higher than some other models in the market. Nonetheless, with a solid customer rating of 4.7 out of 5 stars, this generator is highly regarded for its performance, reliability, and quiet operation, making it a top contender for those prioritizing low noise and consistent power.

The Westinghouse Outdoor Power Equipment 14500 Peak Watt Tri-Fuel Home Backup Portable Generator is a versatile and powerful generator, making it suitable for large homes or as a reliable portable power source. It boasts an impressive power output with 14,500 peak watts and 11,500 running watts on gasoline, 13,500 peak watts and 10,500 running watts on propane, and 12,000 peak watts and 9,500 running watts on natural gas.

This flexibility in fuel type – gasoline, propane, and natural gas – allows for extended runtime and convenience, running for up to 19 hours on a 9.5-gallon fuel tank and up to 7 hours on a 20 lb. propane tank. The heavy-duty 550cc 4-Stroke OHV Westinghouse engine ensures durability and longevity, supported by a 3-year limited service, labor, and parts coverage warranty.

For ease of use, it includes an electric start, overload protection, automatic voltage regulation, and a muffler for noise reduction. However, at 230 pounds, it is quite heavy and may not be the easiest to transport. While it is EPA compliant and has a CO sensor for safety, this generator is highly suitable for homeowners needing a reliable backup power source, though its weight could be a potential drawback for some users.
