| 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 Cummins Onan P4500i is a 3700-watt inverter generator built for users who need reliable power without the noise penalty. Its 4500-watt peak capacity handles startup surges for air conditioners, power tools, and RV air conditioning units. The gasoline engine runs clean enough for sensitive electronics like laptops and phones, thanks to a 3 percent THD rating that protects against voltage spikes. This unit bridges the gap between portable camping generators and stationary backup power, making it useful for RV owners, homeowners facing extended outages, and contractors working near occupied spaces. |
