| Summary | The WEN 56551 is a 5000-watt gasoline generator built around a 389cc 13 HP OHV engine that delivers 5500 starting watts for handling the high inrush current that motors and compressors demand at startup. This wattage ceiling means you can run a mid-sized job site setup, power a home during an outage, or support RV systems without overloading the unit. The 6.5-gallon fuel tank stretches to 11 hours at 50 percent load, reducing refueling frequency during extended operations. A 2-year warranty backs the unit, giving you a defined window of manufacturer support. | The PREDATOR® 6500 Max Starting Watt, 5500 Running Watt Gas Powered Portable Generator is built with reliability and safety in mind. |
