Manufacturer overview

The A-iPower SUA3800i is a powerful and quiet portable inverter generator designed for home backup, RV travel, outdoor events, and recreational use. Delivering 3500 running watts and 3800 starting watts, it provides reliable 120V power while producing clean, stable electricity that is safe for sensitive electronics. Powered by a 223cc Senci OHV 4-stroke gasoline engine, the SUA3800i runs efficiently for up to 12 hours on a single tank and operates at a low noise level of just 63 dB, making it suitable for campsites, tailgates, and neighborhood use. Its pure sine wave output with less than 3% THD ensures smooth and consistent power for modern devices. The generator features multiple power outlets, including two 120V 20A AC outlets, a 120V 30A locking outlet, a USB port, and a 12V DC outlet, offering versatile connectivity for household essentials, tools, and electronics. It is also parallel-ready, allowing you to connect a second compatible unit for increased power when needed. Designed with portability in mind, the SUA3800i uses an enclosed inverter housing to reduce noise and enhance durability. Built-in wheels and a telescoping handle make it easy to move despite its robust construction. A digital control panel provides real-time monitoring of fuel level, power output, voltage, and run time, while integrated safety features such as overload protection and low-oil shutdown deliver added peace of mind.
