Power calculator for the road
Calculate daily consumption, recommended power bank or power station size and required solar power – for Starlink Mini, laptop and more. Runs only in your browser.
Your devices
Example values – replace them with your devices’ ratings (label/datasheet).
| Device | Watts (avg) | Hours/day | Wh | Remove |

Consumption per day–
Recommended battery capacity–
Solar power to recharge per day–
How it calculates
- Consumption per day = sum of watts × hours of all devices.
- Recommended capacity = daily consumption ÷ efficiency × days without recharging × (1 + reserve).
- Solar power = daily consumption ÷ efficiency ÷ full-sun hours ÷ (1 − solar losses).
All assumptions can be changed. Starlink Mini values come from the datasheet (avg 25–40 W); replace other devices with your own ratings.
Background: Powering the Starlink Mini on the road – power bank, power station, solar and Power station for travel and camping – what size do you need?.
