| 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 WEN 56400-CA is a 3500-watt gasoline generator built for homeowners and job site operators who need sustained power without constant refueling. The 4-gallon fuel tank delivers 11 hours of runtime at 50 percent load, meaning a typical workday of moderate electrical demand requires only one fill-up. The 4050-watt peak capacity handles startup surges from air compressors, circular saws, and refrigeration units that draw extra current when they first engage. This wattage tier powers most household circuits simultaneously or runs a small job site with hand tools and lighting. The 2-year warranty covers manufacturing defects across the ownership period. |
