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 WGen3600v is a portable generator offering 3,600 running watts and 4,650 peak watts, powered by a 212cc 4-Stroke OHV engine. It features a 4-gallon fuel tank providing up to 14 hours of runtime, making it suitable for travel trailers and home backup power.
