| 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 Genmax GM5500XiD is a 4000-watt dual-fuel inverter generator that handles essential household loads, power tools, and RV systems simultaneously. Running on gasoline or propane, it delivers clean 3% THD output safe for laptops and televisions. At 68 pounds with a wheel kit included, this unit moves easily between storage and deployment. |
