Model iGen5000DFc EFIThe Westinghouse iGen5000DFc EFI is a dual fuel inverter generator offering 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 reduced maintenance, along with a remote start, 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 EFI is a dual-fuel generator rated at 3900 running watts with 5000 starting watts. That combination gives it enough headroom to handle the extra surge many loads demand at startup while still delivering a strong continuous output once everything is running.
Because it is dual-fuel, the iGen5000DFc EFI gives you the option to run on more than one fuel type, which can be a practical advantage when planning for longer use cases or changing availability.
With 3900 running watts and 5000 starting watts, the iGen5000DFc EFI is built to cover both steady power needs and the brief spikes that happen when equipment kicks on. Its 52 dBA noise level supports use cases where sound matters, including situations where you want power without a loud presence nearby.
Runtime is listed at 12 hours at 25 percent load, giving a clear expectation for extended operation when you are not pushing the generator hard. For power quality, the unit is rated at less than 3 percent THD, a spec that aligns with cleaner output for devices that benefit from steadier electricity.
At 111 lbs, the iGen5000DFc EFI is substantial enough that moving it is a deliberate task rather than a casual lift. Its physical size of 25.1 x 18.1 x 21.2 inches helps you plan where it will fit, whether that is in storage, in a vehicle, or in a dedicated spot where it will run.
Starting flexibility is a highlight here, with Recoil, Electric, and Remote starting systems all included, letting you choose the method that best matches your setup and convenience needs. A built-in fuel gauge and indicators add day-to-day usability by making it easier to monitor status at a glance while it is operating.
The iGen5000DFc EFI is parallel capable, which opens the door to scaling output by linking compatible units when you need more power. It is also RV ready, and it includes a spark arrestor and covered outlets, which together support more controlled operation and better protection for the outlet area. Automatic voltage regulation (AVR) is included, reinforcing steadier delivery as conditions 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.
Westinghouse is renowned for its robust and reliable power generation equipment, offering a wide range of generators suitable for home and commercial use.
