WEN DF1200X 12000-Watt 120-Volt/240-Volt Dual Fuel Transfer-Switch Ready Electric Start Portable Generator with Wheel Kit and CO Shutdown Sensor - DF1200X

Remember when you could run your generator off either gas or propane? Whether we're providing your home electricity during a crisis or charging your family's cellphones at the campgrounds, WEN has been reliably lighting up lives since 1951. Now, with the WEN 12000-Watt Dual Fuel Electric Start Generator, you’ll be able to create power from two different sources. Simply select your preferred method, either gasoline or LPG, and power on the generator using the electric start. Propane provides the generator with 11000 surge and 9000 running watts while gasoline creates up to 12000 surge and 9500 running watts. Our packed panel features four 120V GFCI outlets (5-20R), a 120V/240V 30A twist lock outlet (L14-30R), a 120V/240V 50A outlet (NEMA 14-50R), and a 12V DC cigarette-lighter-style plug. Run your lights, TV, refrigerator, sump pump, power tools, or other essentials with ease. The WEN Watchdog CO Shutdown Sensor helps protect both you and your family by automatically turning off the generator if dangerous levels of carbon monoxide are detected. The wheel and handle kit makes transportation easier than ever while the included LPG hose allows for immediate connection to propane tanks. With its 240 volts of power and 500cc engine, this EPA III compliant generator is the perfect companion for emergency back-up. Simply plug your transfer switch into the NEMA 30A twist lock for electricity in times of need. Fill the gas tank with up to 7.9 gallons of gasoline for a 7.5-hour half-load runtime. It’s durable enough for the job site and compact enough for easy storage. And because it’s a WEN product, your generator comes backed by a nationwide network of skilled service technicians, a friendly customer support phone line, and a two-year warranty. Remember when you didn’t have to worry about the power going out? Remember WEN.

• Check oil level before each use to prevent low-oil shutdowns and engine wear.

• Clean or replace the air filter regularly to ensure proper airflow and fuel combustion.

• Inspect and replace the spark plug per schedule for dependable electric starts.

• Run the generator monthly under load for ~15–20 min to keep fuel lines and seals functioning.

• Drain the carburetor and avoid storing stale fuel; use a fuel stabilizer if storing fuels longer than 30 days.
