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 Westinghouse iGen5000DFc EFI Inverter Generator is a dual fuel generator that offers 5000 peak watts and 3900 rated watts on gasoline, and 4500 peak watts and 3500 rated watts on propane. It features electronic fuel injection for improved fuel efficiency and lower maintenance, remote start, an LED display, and up to 12 hours of run time at 25% load.
