The Champion Power Equipment 201241 13,500-Watt Tri Fuel Portable Generator with CO Shield is designed with your safety and convenience in mind. This natural gas-ready, rugged 13,500-watt generator ensures that the next time there's an outage, the power in your house stays on. For projects, the massive 739cc Milwaukee Series V-Twin engine has what it takes to handle multiple power tools and large equipment, helping you get the job done with ease. When you are not running your generator on natural gas, you also have the option of operating it on gasoline or propane. The ability to operate your generator on three types of fuel out of the box makes this one of the most versatile generators on the market. The Fuel Select dial allows you to safely select gasoline, propane (LPG), or natural gas (NG) as your fuel source. Using gasoline, the generator produces 16,875 starting watts and 13,500 running watts; and will run for 8 hours at 50% load when the 11-gallon fuel tank is full. When using a 20-pound propane tank, it produces 15,000 starting watts and 12,000 running watts; and will run for 3 hours at 50% load. A 6.6-foot propane hose with a built-in regulator is included. Using natural gas, the generator produces 13,750 starting watts and 11,000 running watts. To connect this generator to your home's natural gas source, this generator includes a 25-foot NG hose kit, which includes a female quick connect end, a female flare fitting end, and an NPT male adapter. You'll appreciate the handy electric start with included battery, plus Cold Start Technology ensures a quick start in cold weather. The Intelligauge with Power Meter monitors voltage, frequency and operating hours, while the integrated lift hook, foldaway U-shaped handle and 12 in. never flat tires make it easy to load, unload and move your power where you need it. At 16,875 starting watts and 13,500 running watts, this powerful unit has a durable steel frame and can handle it all in an outage - lights, sump pump, refrigerator, modem/router, security system, window AC, furnace blower, fan, TV/DVD, computer, well pump, microwave and will start and run a central AC with a manual transfer switch (not included). Not only that, but the Volt Guard built-in surge protector prevents overloads and keeps your equipment safe from spikes in voltage. This powerful generator has better fuel economy, lower emissions, and reduced friction for less wear and longer life thanks to the newly designed Milwaukee V-Twin engine. The engine's 90-degree V-win design results in superior balance and low vibration, plus the fan reduces noise and ensures maximum airflow. All the outlets have covers for protection and include 120V 30A (L5-30R) and 120/240V 30A (L14-30R) locking outlets, a 120/240V 50A outlet (14-50R), and two 120V 20A GFCI-protected household duplex outlets (5-20R). From 23 feet, the noise level is 79 dBA, similar to what you'd hear curbside on a busy street. This unit has a low oil shut-off sensor and includes 1.5 quarts of 5W-30 engine oil so all you'll need to buy is gasoline.
