| Summary | The A-iPower SUA4300iD is a 3,450-watt dual-fuel generator that runs on either gasoline or propane. This flexibility means users can refuel based on what's available, whether that's a gas station during an outage or a propane tank for extended storage. The 4,300-watt peak output handles startup surges from refrigerators, air compressors, and power tools without stumbling. At 54.8 lbs, this unit moves easily into trucks, basements, or storage closets, making it practical for homeowners, campers, and job site crews who need power without the burden of a stationary installation. | The Powermate PM4500 is a 4500-watt portable generator featuring COsense® Technology for carbon monoxide protection, a Generac® 224CC OHV Engine, and a 19-hour run time at 25% load. |
