| 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 Powermate PM4500DF is a durable and compact dual fuel portable generator, ideal for home use or DIY projects. It offers 4500 starting watts and 3600 running watts on gasoline, and features a steel frame with integrated wheels and handle for easy transport. |
