| 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 Cat RP3600 is a 3600-watt gasoline generator built for job sites and RV camping. Its 4500-watt peak output handles startup surges for power tools and air conditioners, while the 3600-watt running capacity sustains multiple household circuits or a single large appliance continuously. |
