| Summary | The A-iPower SUA4500 is a 3,500-watt running generator built around a 223cc OHV 4-stroke engine with cast iron sleeves. This wattage class handles essential household appliances, power tools, and small job site equipment without breaking into the heavy-duty contractor tier. The 4,500-watt peak output gives it enough surge capacity to start refrigerators, air compressors, and welders that draw high inrush current. Gasoline fuel means quick refueling at any gas station, and the 4-gallon tank stretches runtime to 14 hours at quarter load or 11 hours at half load. That refueling cycle keeps users in the field longer without constant tank swaps. | The Westinghouse WGen3600c is a portable gas generator delivering 4,650 peak watts and 3,600 running watts, designed for home backup, RV use, and outdoor adventures. |
