| 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 Yamaha EF5500DE is a versatile dual 120/240 volt generator, ideal for emergency backup power for home, cottage, or business, as well as primary power on job sites. It features a 358cc OHV engine, electric start, and offers 5500 watts maximum AC output with outstanding fuel efficiency. |
