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 Pulsar PG4000BiSRCO is a versatile dual fuel inverter generator designed for both gasoline and propane use, delivering up to 4000 peak watts and 3200 running watts. It features remote and electric start options, is RV-ready, and includes CO Sentry technology for safety.
