How long will a portable power station run a Phone Charger?
A Phone Charger draws about 20W. The table below shows how long common power station sizes will run it, after accounting for real-world inverter and battery losses (about 85% of rated capacity is usable).
| Power Station | Continuous |
|---|---|
| 300 Wh | 13 h |
| 500 Wh | 21 h |
| 1,000 Wh | 1.8 days |
| 1,500 Wh | 2.7 days |
| 2,000 Wh | 3.5 days |
| 3,000 Wh | 5.3 days |
| 5,000 Wh | 8.9 days |
Estimates use ~85% usable capacity (depth of discharge + inverter losses). Actual runtime varies with temperature, load variation, and device efficiency.
