The Westinghouse iGen5000DFc EFI Inverter Generator is a dual fuel generator that offers 5000 peak watts and 3900 rated watts on gasoline, and 4500 peak watts and 3500 rated watts on propane. It features electronic fuel injection for improved fuel efficiency and lower maintenance, remote start, an LED display, and up to 12 hours of run time at 25% load.

Here's the quick tradeoff view — what this model does well, and where it may not fit.
The Westinghouse iGen5000DFc is a dual-fuel generator rated for 3,900 running watts and 5,000 starting watts. That combination targets both steady power delivery and the extra surge needed when loads first kick on, while giving you the option to run on two fuel types.
With its dual-fuel design paired to a 5,000-watt starting ceiling, the iGen5000DFc is built to handle real startup demands without losing sight of sustained output, making its 3,900 running watts the number that matters once everything is up and running.
Dual-fuel operation gives the iGen5000DFc flexibility in how you keep power flowing, and its 3,900 running watts and 5,000 starting watts translate into a generator that can support ongoing loads while still covering higher initial draw when equipment starts. For environments where sound matters, the 52 dBA noise level is a concrete figure to weigh against your tolerance for generator noise in close quarters.
Runtime is clearly defined at two load points: 18 hours at 25 percent load and 15 hours at 50 percent load. That spread shows how increasing demand shortens operating time, helping you plan around lighter overnight usage versus heavier daytime draw. For power quality, the 3 percent THD figure signals cleaner output that is better aligned with sensitive electronics than higher-distortion power, and it pairs with the unit’s inverter design for a more controlled electrical supply.
At 105.8 lbs, the iGen5000DFc is substantial enough that moving it is a deliberate task rather than a casual lift, so its physical presence is something to account for when you are planning storage and setup. Its dimensions of 24.5 x 17.5 x 20 inches provide a clear footprint for fitting it into a garage corner, a storage area, or a vehicle cargo space.
Those measurements also help set expectations for where it can sit during operation, since the unit’s size influences how easily you can position it where you want power while still keeping it placed in a stable, sensible location.
Starting flexibility is a standout here, with Recoil, Electric, and Remote starting systems all built in, giving you multiple ways to get the generator running depending on convenience and conditions. Day-to-day operation is supported by a fuel gauge and indicators, which help you monitor status and fuel level without guesswork.
For compatibility and safety-related considerations, the iGen5000DFc lists compliance with EPA and ANSI/PGMA G300-2023, and it includes a spark arrestor along with covered outlets. It is also RV ready, which directly supports RV power needs, and it is parallel capable, allowing you to scale output by pairing it with another compatible unit. Automatic voltage regulation is included as AVR, reinforcing steadier voltage delivery, 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.
