The Champion Power Equipment 201194 9200-Watt Dual Fuel Portable Generator is the perfect combination of versatility and convenience. 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, frequency and run-time hours. Designed with a low oil shut-off switch, this unit includes 1.2-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 select dial that allows for safe switching between fuel sources. Using gasoline, the 459cc Champion engine produces 11,500 starting watts and 9200 running watts, and will run for 10 hours at 50% load when the 7.7-gallon fuel tank is full. It produces 10,350 starting watts and 8280 running watts, and will run for 5 hours at 50% load when using a 20-pound propane tank. Also included is a 6.5-foot propane hose with a built-in regulator. With a noise level of 74 dBA from 23 feet, which is a bit louder than a vacuum, this machine can provide home backup in an outage, plus the Volt Guard™ protects your generator from electrical voltage spikes.
