The math
| Usable capacity | 3,000 Wh × 0.85 = 2,550 Wh |
|---|---|
| Average draw | 90 W running × 1 duty = 90 W |
| Runtime | 2,550 ÷ 90 = 28.3 h |

Questions people ask
How long will a 3,000 Wh power station run Starlink?
About 28.3 hours (about 28.3 hours). A 3,000 Wh power station has roughly 2,550 Wh usable, and Starlink averages about 90 W. Depending on the model the range is about 25.5 to 102 hours.
How many watts does Starlink use?
Starlink says the Standard kit averages 75-100 watts and the Mini averages 25-40 watts. Over a full day that is roughly 2 kWh for a Standard and under 1 kWh for a Mini.
How do you calculate power station runtime?
Hours ≈ capacity in Wh × 0.85 ÷ average watts. The 0.85 allows for inverter and battery losses.
