Starlink Mini Power Calculator
Estimate Starlink Mini or Standard battery runtime and the power station Wh you need. Enter terminal watts, hours online and days away. The calculator multiplies watts × hours, divides by 0.95 for the Mini's USB-C DC supply or 0.85 for AC, then applies optional solar credit.
Daily dish Wh = terminal watts × hours online Daily battery Wh = daily dish Wh ÷ 0.95 (Mini USB-C DC) or 0.85 (AC) Solar offset = min(solar W × 4 effective hours, daily dish Wh) N-day need = max(daily battery Wh × N − solar offset × (N−1), daily battery Wh) Station runtime hours = station Wh × delivery efficiency ÷ terminal watts Results stay in this browser and are not saved.

The Mini averages 25–40W; its boot and snow-melt peaks are near 60W. Standard presets use 75W typical and 100W high load, following the reviewed article.
Frequently asked questions
How many watts does Starlink Mini use?
Starlink rates the Mini at 25–40W average draw, with peaks around 60W during boot-up or snow-melt mode. The larger Starlink Standard dish draws roughly 50–75W — which is why the Mini is the one to get for battery-powered use.
How long will a power station run a Starlink Mini?
Rule of thumb at 35W average: a 288Wh unit runs it about 7 hours, 512Wh about 12 hours, and 1,024Wh a full 24 hours. Powering the dish over USB-C DC instead of the AC wall adapter stretches those numbers another 10–15%.
Can I power Starlink Mini from a USB-C port?
Yes — Starlink sells a USB-C cable for the Mini that runs it from any USB-C PD port delivering 100W (20V/5A). Several power stations have 100W+ USB-C ports built in, which skips the AC inverter entirely and is the most efficient setup.
Can a power station run a full-size Starlink Standard dish?
Yes, but plan around 75–100W average for the current Standard dish — roughly a third of the runtime of a Mini on the same battery. A 1,000Wh unit gives a Standard dish about 8–11 hours, so it's a workday, not a weekend, unless you add solar.
