Is this the right generator for you?
Here's the quick tradeoff view — what this model does well, and where it may not fit.
Pros
- 5,000 peak watts and 3,900 running watts
- Remote electric start with key fob
- LED data center displaying real-time information
- Compact design with telescoping handle and wheels for portability
- Super quiet operation, as low as 52 dBA
- RV Ready TT-30R outlet
- Automatic low oil and carbon monoxide (CO) shutdown
Cons
- Heavy weight at 105.8 pounds
- No outlets listed in specs
Summary
The Westinghouse iGen5000c is a gasoline generator rated at 3900 running watts with 5000 starting watts. That combination gives it a clear split between steady output for ongoing loads and extra headroom for startups, which is useful when devices demand a brief surge before settling into normal operation.
Because it runs on gasoline, the iGen5000c fits shoppers who want a familiar fuel choice while still delivering substantial power in a compact, self-contained generator format.
Power & Runtime
As a gasoline-powered inverter generator, the iGen5000c pairs its 3900 running watts and 5000 starting watts with a stated total harmonic distortion of ≤ 3%, which speaks directly to cleaner power delivery for electronics that benefit from tighter waveform control. Noise is rated at 52 dBA, a figure that supports use cases where keeping sound down matters as much as keeping lights and devices running.
Runtime is clearly defined at two load points: 18 hours at 25% load and 15 hours at 50% load. With a 3.4-gallon fuel tank, those runtimes translate into long stretches between refueling at moderate demand levels, making it easier to plan overnight operation or extended use without frequent interruptions.
Portability
Portability is shaped by both size and weight, and the iGen5000c lands at 105.8 lbs with dimensions of 24.5 x 17.5 x 20 inches. Those measurements give a concrete sense of the footprint it will occupy in storage or transport, while the triple-digit weight signals that moving it is a more deliberate task than carrying a small unit by hand.
Features
For RV use, the iGen5000c is explicitly RV ready, which aligns the generator with setups that need a straightforward connection for RV power needs. Westinghouse also backs it with a 3-year warranty, adding a defined coverage term that can matter when the generator is intended for recurring seasonal use or relied on for backup situations.
Recommended Audiences
- RV owners needing RV-ready power
- Owners of sensitive electronics seeking clean inverter power
- Shoppers who prefer gasoline-powered generators
- Homeowners needing emergency backup for essential circuits

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.
