| 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 Generac GP3600 (#7678) is a 3600-watt gasoline generator built for homeowners and job sites needing reliable backup or portable power. Its 4500-watt peak capacity handles starting surges for tools and appliances, while the 3.7-gallon fuel tank delivers 9.3 hours of runtime at half load. Automatic voltage regulation protects sensitive electronics, and a three-year warranty covers ownership support. |
