Summary
The Westinghouse WGen14500c is a gasoline generator built around substantial output, delivering 14,500 running watts with 18,000 starting watts. That combination targets situations where both steady power delivery and the ability to handle demanding startup surges matter.
Because it runs on gasoline, the WGen14500c pairs its high wattage with a 10.5-gallon fuel tank, setting it up for longer operating stretches without frequent refueling.
Power & Runtime
With 14,500 running watts and 18,000 starting watts on gasoline, the WGen14500c is designed to keep large electrical loads running while also handling the higher initial draw that can occur when equipment first turns on. Its total harmonic distortion is listed as under 5 percent, which speaks to cleaner power delivery for connected devices.
Noise is rated at 74 dBA, giving a clear reference point for what to expect while it is operating. On runtime, Westinghouse lists 16 hours at 25 percent load and 11 hours at 50 percent load, tying endurance directly to how heavily the generator is being used.
Portability
At 352 lbs and measuring 34 x 31 x 35 inches, the WGen14500c is a sizable unit that prioritizes output and fuel capacity over compactness. Those dimensions and weight are important practical considerations for where it can be stored and how it will be moved into position for use.
Features
Starting is handled through an electric and remote starting system, which supports push-button operation and the convenience of initiating startup from a distance. A built-in fuel gauge helps you monitor fuel level in the 10.5-gallon tank so you can plan refueling around your runtime needs.
For safety and standards alignment, the generator lists EPA and ANSI/PGMA G300-2023 compliance, and it includes a spark arrestor. Covered outlets add a layer of protection at the connection points, while GFCI outlets provide additional electrical safety. Automatic voltage regulation is included to help maintain steadier output as conditions change, and the generator 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.
