Performance

The performance of the WEN 56477i is where it truly stands out—offering a combination of high wattage, portability, and quiet operation.

Power Output and Efficiency

Generating up to 4800 surge watts and 4000 continuous watts, this unit can easily support mid-sized appliances, power tools, and electronic devices. Whether you’re using it for an RV trip, tailgating event, or as a backup during outages, it handles multiple tasks simultaneously without faltering.

Runtime and Fuel Economy

Thanks to its 1.9-gallon fuel tank, the generator runs for up to 7 hours at half load, which is quite efficient. Enabling Eco-Mode extends fuel efficiency by adjusting the engine’s RPM based on real-time power draw. This is a major plus for long-term usage and reducing gas consumption.
