| Summary | The DEWALT DXGN4500 is a 4200-watt gasoline generator built around a Honda GX270 engine, positioning it as a workhorse for job sites and extended outdoor use. At 160 pounds, this unit sits at the heavy end of the portable generator spectrum, meaning it stays put once deployed rather than moving between locations. The 7-gallon fuel tank stretches to 15 hours at half load, so users can power a full day of work or an extended event without refueling. The dual-voltage output (120V and 120/240V) lets contractors run both household circuits and heavy equipment from a single machine. | The Ryobi RY904500 is a 3600-watt portable gasoline generator, delivering 4500 starting watts. It features a 212cc OHV engine, a 4-gallon fuel tank providing up to 10 hours of runtime at 50% load, and is RV-ready with a 120V 30A RV outlet. |
