| Summary | The A-iPower SUA4300i is a 3,450-watt inverter generator built for users who need portable backup power without sacrificing portability. At 52.9 lbs, this gasoline-powered unit bridges the gap between job site tools and home emergency backup. The 4,300-watt peak output handles starting surges on refrigerators, air compressors, and power tools, while the 3,450-watt running capacity sustains them once they spin up.
With a 1.6-gallon fuel tank, the SUA4300i runs 7.5 hours at 25 percent load, meaning a full tank covers a full workday or overnight outage without refueling. The recoil start system is simple and reliable, though it requires manual pulling. At 62 dB, the noise level sits at normal conversation volume, making it acceptable for residential neighborhoods and campgrounds where quieter operation matters. | The Genmax GM4600iAEFIC is a 3800-watt gasoline inverter generator built for users who need portable power without sacrificing output control. Its 4600-watt peak capacity handles startup surges, while the inverter design keeps electricity clean enough for laptops and sensitive devices. One person can move it. |
