Estimated runtime examples
Estimated runtime = capacity_wh × 0.85 ÷ device_watts. This is a calculation using an assumed 85% usable efficiency — never a guaranteed or tested figure. Real runtime depends on the device, its duty cycle and temperature.

|---|---|---|
| Full-size refrigerator (~150 W avg) | 150 W | 4.7 h |
| CPAP machine (~40 W) | 40 W | 17.6 h |
