The quiet and powerful Westinghouse iGen12000TFc portable inverter generator with CO sensor produces up to 12,000W peak and 9,000W with less than 3% THD, making it an ideal solution for home backup power even for sensitive electronics. With a traditional generator's power and the benefits of an inverter, it's the best of both worlds. Enjoy quiet operation as low as 64 dBA and Eco Mode. The heavy duty 457cc 4-Stroke OHV Westinghouse tri fuel engine can go all day or night with a runtime of up to 19 hours at 25% load on a 7.9 gallon gas tank, among the largest of inverter generators of its size. Features a cast iron sleeve, digital fuel gauge, auto low oil shutdown. A push button electric start and remote start key fob make starting the iGen12000TFc extra convenient. Outlets include transfer switch or interlock kit ready 14-50R 50A and L14-30R 30A outlets. Each can run major appliances like air conditioners, refrigerators, and sump pumps along with any lights or entertainment centers at the same time on a single cord. It also has an ST Switch outlet, a GFCI duplex 20A outlet, and is parallel ready. An LED data center gives updates on fuel, voltage output, frequency, lifetime hours and maintenance, removing all guesswork. Easily portable with heavy duty, never flat wheels and foldable handle, it'll have your house, RV or jobsite powered in seconds. Includes a 3 year limited warranty and lifetime technical support backed by our nationwide Westinghouse Customer Service Network.

Q&As

Q: how long will this generator run for on a 15 lb propane tank?

a month ago
1 Answer
  • A: Thank you for your question. The manufacturer rates this generator at about 9.8 hours of runtime on propane at 25% load using a standard 20 lb tank. A 15 lb tank will run the unit, but expect shorter runtime, generally around 7–8 hours depending on load.

Too Early of a Review

Bryan Andres, 6/13/26: I just bought it. Have not used it yet so another review will be coming. It looks great and well made. I gave a 4 rating because: 1) Had to do the review when registered to get a free cover 2) The quick-connect battery plug is damaged so will contact the company for a replacement

Have not done the first startup yet but I have put it together and even though heavy, easy to set up. I noticed black matter, like sand in the packaging. We will see how it runs.

Yes, I recommend this product.
