Starlink Mini Power Calculator

Enter your battery and how you use the dish. Everything runs in your browser; nothing is sent anywhere. For the reasoning behind the numbers, read Starlink Mini battery runtime: how long will it run off-grid?

Battery size in
Starlink's spec: 25–40 W average (spec sheet). 30 W is a middle value; use 40 W for cold or snow.

How it works

Runtime (hours) = battery Wh × efficiency ÷ watts. Days = runtime ÷ hours used per day. If you entered Ah, Wh = Ah × volts.

Where the estimate falls short: it assumes the Mini is the only thing on the battery, ignores solar charging, and uses rated capacity. Cold weather, aging batteries and inverter idle draw all cut real runtime. Treat the result as a best case.
