The Westinghouse WGen11500TFc is a versatile tri-fuel portable generator capable of operating on gasoline, propane, or natural gas. It delivers up to 14,500 peak watts and 11,500 running watts on gasoline, making it suitable for home backup, job sites, or recreational use. The generator features a 550cc 4-Stroke OHV engine, electric start with remote key fob, and a CO sensor for safety. It offers a runtime of up to 19 hours on a 9.5-gallon fuel tank and includes multiple outlets for various applications.

Here's the quick tradeoff view — what this model does well, and where it may not fit.
The Westinghouse WGen11500TFc is a tri-fuel generator built around substantial output, delivering 11,500 running watts and 14,500 starting watts. That combination targets situations where both steady power and extra surge capacity matter, letting the unit handle ongoing demand while also accommodating higher start-up pulls.
Its tri-fuel design adds flexibility to how you keep it running, pairing that multi-fuel capability with the sheer wattage needed for demanding applications.
With 11,500 running watts and 14,500 starting watts, the WGen11500TFc is set up to support large electrical loads, with the higher starting figure helping when equipment needs extra power to get moving. The tri-fuel setup broadens fueling options, which can be valuable when planning for longer outages or varied use cases.
Noise is rated at 74 dBA, giving a clear expectation for how loud it runs during operation. For endurance, it is rated for 19 hours of runtime at 25 percent load and 9.5 hours at 50 percent load, tying run time directly to how hard you work the generator. Power quality is supported by a THD rating of less than 5 percent, which speaks to cleaner output for connected devices.
At 230 lbs, the WGen11500TFc is a heavy portable unit, and its physical footprint of 28.9 x 29.6 x 26.9 inches sets expectations for storage space and where it can be placed during use. Those dimensions and weight together point to a generator that benefits from deliberate placement and planning when moving it into position.
Starting is a major convenience highlight here, with recoil, electric, and remote starting systems all included, giving you multiple ways to bring the generator online depending on preference and situation. A built-in fuel gauge helps you monitor fuel status at a glance, supporting better planning around refueling.
On the safety and usability side, the generator includes a spark arrestor, covered outlets, and GFCI outlets, which adds practical protection for both the receptacles and connected use. Automatic voltage regulation is included as well, reinforcing steadier output as conditions change. Compliance is listed as EPA and ANSI/PGMA G300-2023, and the package is backed by a 3-year warranty.

These are estimates using typical wattage assumptions. Real appliances vary. Startup surges can be 2–6× the running wattage for motor-driven loads. 240V loads require a 120/240V generator and proper connection. Use a transfer switch or interlock kit; never backfeed a panel.
Westinghouse is renowned for its robust and reliable power generation equipment, offering a wide range of generators suitable for home and commercial use.
