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
- Lightweight at only 61.7 lbs
- Includes electric start and remote start
- Runs for up to 7 hours on a single tank
- Super quiet—52 dBA noise level
- Supports sensitive electronics with low THD
Cons
- No mention of GFCI outlets
Summary
The Westinghouse iGen4000c is a gasoline generator rated for 3300 running watts, giving it a solid power ceiling for everyday portable use while still keeping its output in a clearly defined class. It is built around an inverter design, pairing that 3300-watt running rating with 4000 starting watts for handling brief startup surges.
Westinghouse describes its broader lineup as robust and reliable power generation equipment with options suited to home and commercial use, and the iGen4000c fits into that theme as a compact gasoline-powered model with a clearly stated power rating.
Power & Runtime
On gasoline, the iGen4000c delivers 3300 running watts and 4000 starting watts, matching the highest running-watt rating shown for its fuel. Noise is listed at 52 dBA, which puts an emphasis on quieter operation for a generator with this output level, especially for situations where sound matters.
Runtime is given as 7 hours at 25 percent load, and total harmonic distortion is listed at 3 percent, which speaks to clean inverter power for electronics that benefit from tighter waveform control. The unit is also labeled as having AVR (automatic voltage regulation), reinforcing a focus on maintaining steadier output.
Portability
At 61.7 lbs, the iGen4000c keeps weight in a range that supports genuinely portable use, especially for owners who want meaningful power without moving an oversized machine. Its dimensions of 21.3 x 12.6 x 19.3 inches further underline that it is designed to be carried and stowed without demanding a large footprint.
Features
Starting flexibility is a strong point here, with recoil, electric, and remote starting systems all listed, letting you choose between straightforward pull-start operation and more convenience-focused options. A fuel gauge is included, and indicators are present as well, helping you monitor the generator during use.
The iGen4000c is EPA compliant and includes a spark arrestor, and it is both parallel capable and RV ready, supporting tandem operation for more output and direct compatibility for RV use. Covered outlets add a practical layer of protection, 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.
