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 Jackery Solar Generator 1000 v2 is a solid choice for a quiet and portable power source suited for camping, road trips, or emergency backup. It utilizes LiFePO4 battery and inverter technology, producing clean, stable power quietly compared to traditional gas generators. Its 30 dB overnight charging mode indicates very quiet operation during use.

Featuring a 1,500-watt continuous output and 3,000-watt surge capacity, it can support common appliances like refrigerators and small AC units, making it versatile for both outdoor and home applications. The 1,070Wh battery capacity provides a decent runtime, and the fast charging option allows the unit to fully recharge in about an hour when emergency mode is enabled, which is convenient but may slightly affect battery health if used frequently.

Weighing approximately 32 pounds and equipped with a foldable handle, the unit offers reasonable portability, though it might be somewhat heavy for long-distance carrying. The built-in app control enhances user experience by allowing easy mode switching to optimize quietness and efficiency. The solar panel is sold separately, adding to setup complexity and cost. While the battery boasts a long lifespan of over 10 years with proper care, the 2-year warranty may be considered short relative to the price. This generator is a dependable, eco-friendly option that is easy to use and charges quickly.

The Jackery Solar Generator 300 is a lightweight, quiet inverter generator ideal for camping, RV trips, or emergency backup situations where noise is a concern. It weighs just under 13 pounds and features a sleek handle, making it easy to carry. Powered by a 293Wh LiFePO4 battery with a 300W rated output (600W surge), it efficiently runs small devices like laptops, cameras, and CPAP machines, though it won't support heavy appliances.

Being battery-powered and solar-charged, it produces almost no noise, distinguishing it from conventional gas generators. The included 40W solar panel enables off-grid charging, reaching 80% capacity in about 7.5 hours, which suits longer trips but might be slow for urgent power needs. Its battery is durable with over 4,000 charge cycles, promising a long service life. Multiple ports (AC, USB-C, USB-A, and car) allow versatile device charging.

The power output is limited to 300W, so it is not suitable for running large or multiple high-wattage devices simultaneously. Additionally, the smaller 40W solar panel means slower solar recharge unless paired with higher wattage panels sold separately. For users seeking a truly silent and portable generator for small electronics with eco-friendly solar charging, the Jackery 300 is a solid choice. Those requiring more power or faster solar recharge should consider larger models or additional panels.
