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 Champion Power Equipment 201501 3650-Watt RV Ready Portable Generator with CO Shield® offers versatile and convenient power, featuring a 224cc engine, 4550 starting watts, 3650 running watts, and up to 14 hours of run time at 50% load. It includes CO Shield® carbon monoxide auto shutoff system, making it ideal for camping, home backup, and more.
