What size power bank for a Starlink Mini?
At the top of Starlink’s 25–40 W average, a 300 Wh power bank or station on its DC output runs a Starlink Mini about 7.1 hours (7 h 7 min). For a full day you want roughly 1,000 Wh.
How to work it out
- 300 Wh = 300 Wh available
- 40 W ÷ 95% DC converter = 42.1 W
- 300 Wh ÷ 42.1 W = 7.1 hours (7 h 7 min)
Starlink’s spec sheet gives the Mini an average draw of 25–40 W and an input rating of 12–48 V at 60 W. It also notes a USB-C Power Delivery requirement of 100 W (20 V, 5 A) when using its USB-C to barrel cable — so a power bank must deliver that much, not just store enough.

Choosing a power bank for the Mini
- Output first, then capacity. A bank that can’t supply 100 W USB-C PD (or the 60 W input rating through a 12 V port) may shut off or fail to boot the dish, however many watt-hours it holds.
- Watt-hours, not mAh. Power banks are often labelled in mAh at 3.6–3.7 V cell voltage. Convert to Wh (mAh × V ÷ 1,000) before comparing with this table. A 100 Wh bank gives a little over 2 hours of Mini use.
- Skip the AC outlet. Running the Mini through a power station’s AC outlet and its own power brick adds an inverter loss and idle draw — the DC route stretches the same battery.
- Cold weather costs more. Snow melt raises the draw, so a winter day sits at or above the top of the range.
Daily energy for the Mini is worked out on how much power the Starlink Mini uses; for the full-size dish, see how much power Starlink uses per day. The table below shows the same 40 W on other sizes.
