Keep your family safe during power outages and natural disasters with the WEN 6,250-Watt RV and Transfer-Switch Ready Inverter Generator. The included inverter provides clean energy, free of voltage spikes and drops. Our 301cc 4-stroke OHV engine produces up to 6250 surge watts and 5000 rated watts of power, making this the perfect backup generator in case of emergencies. Designed to mirror a pure sine wave, this unit limits total harmonic distortion to under 0.5% at no load and under 1.5% at full load, making it safe to run laptops, cellphones, monitors, tablets and other sensitive electronics. Our ultra-efficient 4.2 Gal. tank provides up to 8.1-hours of half-load run time. The fully-packed panel comes equipped with two 3-prong 120-Volt NEMA 5-20R receptacles, two 5-Volt USB ports, one 120-Volt to 240-Volt transfer-switch-ready NEMA L14-30R twist lock receptacle, and one 120-Volt RV-ready TT-30R receptacle. Maximize fuel economy and runtime by engaging the eco-mode switch. This allows the generator’s engine to automatically adjust its fuel consumption as items are plugged into and unplugged from the panel, minimizing noise and fuel usage whenever possible. The lightweight body weighs 30% less than a traditional 6250-Watt generator, while the included wheel and handle kit makes for easy transport and storage between uses. The panel’s data meter monitors the voltage, frequency, total runtime, and session runtime. Backed by a 2-year warranty.
