| Summary | The WEN GN5600M is a 4500-running-watt gasoline generator built to handle home backup essentials, jobsite tools, and recreational power needs. Its 5600 starting watts give it enough surge capacity to start compressors, pump motors, and other high-inrush devices without stalling. A 4.36-gallon fuel tank paired with 12.5-hour runtime at 50 percent load means you can power moderate loads overnight or through a full workday without refueling. At 98.7 lbs with a 25.4 x 23.6 x 22.9-inch footprint, it strikes a balance between meaningful output and garage-friendly storage. The 3-year warranty covers residential use, making it a straightforward choice for buyers who want proven wattage without stepping into heavier, open-frame territory. | 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. |
