For your RV, you can power one 15,000 BTU RV air conditioner. Whether you need power for your home or next project, Champion Power Equipment makes powering your life more convenient than ever. The convenient electric start includes a battery, plus Cold Start Technology ensures a quick start in cold weather. Easily monitor power output and track maintenance intervals with Intelligauge, which allows you to keep track of voltage, hertz and run-time hours. Designed with a low oil shut-off sensor, this unit holds 0.6-quarts of 10W-30 oil. Operate your Dual-Fuel generator right out of the box on gasoline or propane, and easily switch fuels with our patented fuel selector switch that allows for safe switching between fuel sources. Using gasoline, the 224cc Champion engine produces 4000 starting watts and 3500 running watts, and will run for 9 hours at 50% load when the 3.4-gallon fuel tank is full. It produces 3600 starting watts and 3150 running watts, and will run for 10.5 hours at 50% load when using a 20-pound propane tank. Also included is a 3.3-foot propane hose with a built-in regulator. With a noise level of 68 dBA from 23 feet, which is about as loud as a vacuum cleaner, this machine can provide home backup in an outage, plus the Volt Guard built-in surge protector prevents overloads and keeps your equipment safe.
