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 Westinghouse 28000 Peak Watt Home Backup Portable Generator is a powerful gas-powered unit delivering 28,000 peak watts and 20,000 running watts, making it suitable for heavy-duty home backup needs. It runs up to 11 hours at half load on a large 17-gallon fuel tank, which is good for extended power outages. The generator features convenient electric push-button start and remote start via key fob, plus safety features like a CO sensor and automatic shutoff for low oil or dangerous carbon monoxide levels.

While it delivers strong power, this model is quite large and heavy at over 600 pounds, which impacts portability; it has reinforced steel handles but is not something you'd easily move around frequently. It does not include inverter technology, which means it may not provide the cleaner, quieter power needed for sensitive electronics and might be louder than quieter inverter generators typically used in this category.

In terms of outlets, it offers a wide variety including standard household and high-amperage outlets, making it versatile for different power needs. This generator is best suited for homeowners looking for a reliable and high-capacity backup power source rather than for those prioritizing quietness or portability. If you need a rugged, powerful generator for long runtimes during outages and don’t mind some noise and size, this is a solid choice. However, if quiet operation and easy transport are your top priorities, you might want to explore inverter generators designed specifically with those features.

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.
