Overview

Cummins builds this portable inverter generator around a small four stroke OHV engine with a pull start and a single stop, run and choke switch. An LED display reports fuel, output, remaining run time, voltage and lifetime hours.

The display is the standout, showing how long the tank will last at the current load. Output covers lights, fans, a fridge or electronics at a campsite. Noise level and distortion figures are not given, and there is no electric start.

Who it's for

Campers, tailgaters and small homes needing a few essentials during an outage. RV owners running rooftop air should look at a larger generator.

Pros and cons

Pros
  • Detailed LED display
  • Lifetime hour meter for upkeep
  • USB ports for phones and tablets
  • Simple single switch control
Cons
  • Pull start only
  • Noise level not listed
  • Outlet types unstated

Performance notes

Running watts set the continuous load, and the peak margin covers short motor starts. Runtime falls as load rises, which the display tracks in real time. Inverter designs throttle the engine to the load, though this listing gives no noise or distortion figures.
