- noise level of 74 decibels
Summary
The Westinghouse WGen9500DFc EFI is a dual-fuel generator rated at 9,500 running watts with 12,500 starting watts. That combination points to a unit built to handle sustained electrical demand while also providing extra headroom for the higher surge required when certain equipment first powers on.
Because it is dual-fuel, the WGen9500DFc EFI gives you flexibility in how you run it, which can matter when you are planning for longer outages or varying fuel availability while still keeping the same 9,500 running watts and 12,500 starting watts on tap.
Power & Runtime
With 9,500 running watts and 12,500 starting watts, this generator is set up to support steady loads and also accommodate brief startup spikes without immediately overloading. In practical use, that starting-watt capacity is what helps when devices demand extra power at the moment they kick on, while the running-watt rating is what you can lean on for continuous operation.
Noise is listed at 74 dBA, which gives a concrete sense of its operating loudness when it is running. For runtime, it is rated for 12 hours at 25 percent load, offering a clear expectation for extended operation at lighter demand. Total harmonic distortion is listed at 23 percent, which describes the waveform cleanliness of the output and is a key number to consider when you are thinking about how the power quality aligns with what you plan to run.
Portability
The WGen9500DFc EFI weighs 221 lbs, so moving it is a meaningful part of ownership and something you will plan around when positioning it for use. Its physical size is listed as 27.3 x 20.6 x 22.5 inches, which helps you gauge where it can be stored and how much space it will occupy when set up for operation.
Features
Starting is handled through a mix of recoil, electric, and remote options, giving you multiple ways to get the generator running depending on what is most convenient in the moment. A fuel gauge is included, which supports quick at-a-glance checks so you can monitor fuel status during operation without guesswork.
On the safety and usability side, it includes a spark arrestor, covered outlets, and GFCI outlets, combining protection for the outlet area with added electrical safety through GFCI protection. Automatic voltage regulation is also built in, which is designed to help keep output steadier as loads change. Compliance is listed as CARB, EPA, and ANSI/PGMA G300-2023, 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.
