    Summary

    The Westinghouse WGen9500c is a gasoline generator built around 9,500 running watts and 12,500 starting watts, giving it the headroom to handle both steady electrical demand and the extra surge needed when equipment first kicks on. With gasoline as its fuel type, it is designed for users who want a straightforward refueling routine paired with high output.

    Power & Runtime

    With 9,500 running watts available for continuous use and 12,500 starting watts for startup surges, the WGen9500c is geared for situations where loads can fluctuate and some devices demand extra power at the moment they start. Its 74 dBA noise level sets expectations for an audible presence during operation, which is a practical consideration when running it near living or working areas. Runtime is clearly defined at two common load points: it runs for 12 hours at 25 percent load and 8 hours at 50 percent load, supported by a 6.6 gallon fuel tank that helps translate fuel capacity into meaningful operating time.

    Portability

    At 209.1 lbs, the WGen9500c is a substantial unit, and that weight is an important factor when planning how it will be moved and set in place. Its physical footprint is 27.2 x 26.1 x 26.5 inches, which helps set expectations for storage space and for where it can be placed during use, especially when you want a stable spot that accommodates its size.

    Features

    Starting flexibility is a standout here, with a starting system that includes recoil, electric, and remote options, letting you choose between manual pull starting, push-button convenience, or starting from a distance. A fuel gauge is included, which supports better planning by making it easier to track fuel status during longer runs. Compliance is listed as CARB and EPA, and a spark arrestor is included, pairing regulatory alignment with a safety-focused component. Practical protection features are also present, including covered outlets and GFCI outlets, and AVR is built in to provide automatic voltage regulation. Westinghouse backs the WGen9500c with a 3-year warranty, adding a defined term of coverage to the overall package.

    Recommended Audiences

    • Shoppers who prefer gasoline-powered generators
    • Homeowners needing whole-house or jobsite backup power
    • Users who value push-button or remote start convenience
    • DIY enthusiasts and hobbyists needing reliable portable power

    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.
