UDPOWER Portable Power Stations Fridge Runtime Comparison
Pick common fridge wattages, tweak assumptions, and compare estimated runtimes for C200, C400, C600, and S1200.
1) Fridge Wattages (multi-select)
Wattage is the running draw. Use the duty cycle below for typical on/off cycling.
2) Inverter Efficiency
90% AC conversion efficiency
3) Usable Capacity
100% De-rating for temp/aging/reserve
4) Compressor Duty Cycle
ON ratio 50% Average W = running W × duty
5) Models & Capacities (Wh)

Estimated Runtime (hours)
Formula:
hours = Wh × usable × efficiency ÷ (running_W × duty). Estimates vary with temperature, door openings, surge behavior, wiring losses, etc.
