10 Best Quietest Generators 2025 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 2000 v2 is a strong choice if you're looking for a quiet, portable power source with solar charging capability. It produces up to 2200 watts, enough to run many home backup devices, camping gear, or small business equipment. Its LiFePo4 battery technology promises safety, long life (up to 10 years), and silent operation since it produces no fumes like gas generators. The generator includes 2x200W solar panels for eco-friendly charging, and can also charge quickly via AC power or an emergency super charge mode.

One of its standout features is the very quiet charging mode that operates at just 30 decibels, allowing you to work or sleep without noise disruption. At 39.5 pounds and with a compact design, it’s more portable than many comparable power stations, though it’s still a bit heavy to casually carry for long distances. The 20ms UPS switching ensures your devices won’t lose power during outages, which is great for critical electronics.

The main drawback is the cost and the fact that solar panels may ship separately, which could complicate setup a bit. Also, while it’s quieter than traditional gas generators, it’s not silent since it has fans for cooling. This generator suits those prioritizing clean, quiet power with versatile charging options, especially for home backup or outdoor use where noise level matters.
