- Weight of 40 pounds may impact portability
Summary
The Westinghouse iGen2550c is a gasoline generator rated at 1800 running watts with 2550 starting watts. That combination targets portable power needs where steady output matters for continuous loads, while the higher starting wattage helps handle brief startup surges.
Because it runs on gasoline, the iGen2550c fits users who want a familiar fuel option while still keeping output within a compact, inverter-style power range.
Power & Runtime
With 1800 running watts and 2550 starting watts, the iGen2550c is built to sustain moderate electrical demand and still accommodate short bursts of extra power when devices first kick on. Its 52 dBA noise level supports use in settings where quieter operation is valued, since lower decibel ratings translate to less intrusive sound during extended runs.
Runtime is rated at 11.5 hours at 25 percent load, giving it the endurance to cover long stretches of light-duty use from a single fill of its 1.11 gallon fuel tank. Power quality is reinforced by a THD rating of less than 3 percent, which aligns well with running sensitive electronics that benefit from cleaner, more stable output.
Portability
At 40 lbs, the iGen2550c stays within a weight range that many people can move without needing a second person, supporting its role as a portable generator for travel and temporary setups. Its listed dimensions of 18.5 x 11 x 18 inches also help it fit into tighter storage areas, making it easier to pack alongside other gear.
Features
Starting is handled through a recoil starting system, keeping operation straightforward and fully manual. Day-to-day monitoring is supported by a fuel gauge and built-in indicators, which help you keep track of fuel status and basic operating conditions while the generator is running.
The iGen2550c is parallel capable, letting you connect it with a compatible unit to scale output when your power needs grow. It is also RV ready, and it includes a spark arrestor and covered outlets, adding practical protections for outdoor use and for keeping the receptacles shielded when not in use. Automatic voltage regulation is included as well, supporting steadier voltage delivery under changing loads. Compliance is listed as CARB and EPA, 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.
