Summary
The Westinghouse WGen3600c is a gasoline generator built around 3600 running watts and 4650 starting watts. That combination gives it a clear split between steady output for ongoing loads and extra surge capacity for equipment that needs a stronger push at startup.
With gasoline as its fuel type, the WGen3600c keeps refueling straightforward while delivering a wattage range that suits both continuous use and short bursts of higher demand.
Power & Runtime
Running at 3600 watts with 4650 starting watts, the WGen3600c is set up to handle stable power delivery while also accommodating startup surges that can trip up lower-surge units. In practical use, that starting headroom matters when devices draw extra power for a moment before settling into their normal running level.
On the runtime side, it is rated for 14 hours at 25 percent load and 10.5 hours at 50 percent load, paired with a 4 gallon fuel tank. Noise is listed at 68 dBA, giving you a concrete reference point for how present the generator will be when operating nearby. Total harmonic distortion is rated at 23 percent, which is a direct indicator of the waveform distortion level the generator produces.
Portability
At 106.1 lbs, the WGen3600c is a substantial portable unit that calls for deliberate handling when moving it into place. Its physical footprint is listed as 23.3 x 22.8 x 21.3 inches, which helps set expectations for storage space and for fitting it into a garage corner, shed, or a dedicated spot near where it will be used.
Features
Starting is handled through a recoil starting system, keeping operation straightforward and fully manual. A built-in fuel gauge supports day-to-day use by giving you a direct read on fuel level, which pairs well with the stated runtime figures when planning refueling breaks.
The WGen3600c lists CARB and EPA compliance, and it is marked as RV ready for RV-oriented power needs. It also includes a spark arrestor and covered outlets, both of which add practical protection during operation and when the unit is not actively in use. Automatic voltage regulation is included as AVR, 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.
