The Champion Power Equipment 76533 3800 Watt Dual Fuel RV Ready Portable Generator with Electric Start operates off GAS or PROPANE straight out of the box (propane hose included). On gasoline the generator will produce 4750 starting watts and 3800 running watts, and on propane 4275 starting watts and 3420 running watts. The generator also comes with a battery for easy Touch Start: push-button electric start which includes an internal battery charger that charges the batter as the generator runs. It makes a great addition to your RV as well as a cost effective and convenient solution for power outages or other emergency situations. It comes travel-ready with a standard 30A RV outlet with enough power to start and run a 15,000 BTU RV air conditioner. This unit also makes a great solution for backup power during an emergency and will power the essential items you need in a power outage – lights, sump pump, refrigerator, modem/router, furnace blower, fan, TV/DVD, computer, smartphone/tablet charger, etc. Since propane has such long stable shelf life you don't need to worry about having fresh gasoline on hand during an emergency. The 3800 Watt Dual Fuel Portable Generator operates at 68 dBA from 23 ft. and has a run time of up to 9 hours on a full tank of gasoline or 10.5 hours on a 20 lb. propane tank at 50% load. The generator features Volt Guard, a built-in surge protector which protects your appliances from any spikes in voltage above a safe threshold, as well as Cold Start technology which optimizes the generator to start easily in cold weather. The generator is portable and comes in a durable steel frame with a folding handle and never-flat tires for easy maneuvering and transportation. The 3800 Watt Dual Fuel Portable Generator comes with a patented fuel selector switch that allows for quick and safe switching between fuel sources. It also comes with 120V 30A RV (TT-30R), 120V 30A locking (L5-30R) and two 120V 20A household outlets (5-20R). The Intelligauge (volts, Hz, hours) allows you to easily monitor power output and track maintenance intervals.
