Starlink Power Use Calculator

Staying connected costs battery. See how much.

Starlink power use depends on the model, the weather and how hard it works. Use the figure from your own app or meter if you have one. Everything is worked out in your browser. Nothing is saved or sent anywhere.

    What this does and doesn't tell you

    • Starlink uses more power in cold or wet weather when it heats itself, and while it is finding satellites.
    • Turning it off overnight saves a lot.
    • Work on 240V AC wiring, including inverter outputs and mains inlets, must be done by a licensed electrician. For high-current DC gear, follow the maker's installation manual and have an auto electrician check your work if you're unsure.
