| Summary | The Genmax GM3500iAED is a 3,200-watt dual-fuel inverter generator that runs on gasoline or propane. At 56.2 lbs, it handles essential household loads like refrigerators and small power tools while remaining portable enough for camping or job sites. The 62 dB noise level keeps it residential-friendly. | The Aceup Energy AI4000s supplies 3,200 running watts for household essentials, campsite equipment, and power tools. Its 4,000 starting watts help cover brief startup surges, while an 8-hour runtime at 50% load gives users a clear refueling interval under moderate demand. Parallel capability allows a compatible second unit to expand available output. |
