In short: According to the datasheet the Mini needs 12–48 V DC (60 W rated) and 25–40 W on average. Via USB-C it only works with a source delivering 100 W at 20 V/5 A, plus the right cable. Runtime ≈ usable watt-hours ÷ consumption. A 99 Wh power bank lasts roughly 2–3.5 hours on paper. As of October 2026.

The official datasheet values: input voltage 12–48 V DC, rated power 60 W, average consumption 25–40 W. Actual consumption depends on how much data flows, how clear the view of the sky is and how cold it is. During start-up and with snow melt enabled it’s briefly higher according to accessory retailers’ measurements (40–60 W at start and 50–70 W when melting are cited) – those are retailer figures, not Starlink values.

USB-C Power Delivery: the most common source of error

Many people buy a powerful power bank and wonder why the Mini won’t start. The reason: it needs a USB-C PD source of at least 100 W, i.e. 20 V at 5 A. Phone chargers and many car adapters with 30 or 45 W aren’t enough. You also need a cable rated for 5 A and the USB-C to Mini barrel-plug adapter (Starlink sells its own USB-C cable).

  • Power bank/charger: output „100 W“ or „20 V ⎓ 5 A“ on one port
  • Cable: rated for 5 A / 100 W
  • Adapter: USB-C to the Mini’s barrel plug
  • Test at home before the trip – including start-up

Work out the runtime yourself

The formula is simple:

Runtime (h) ≈ capacity (Wh) × efficiency ÷ consumption (W)

We assume 85 % efficiency (conversion losses). If the power bank only states mAh: Wh = mAh × cell voltage (usually 3.6–3.7 V) ÷ 1,000.

Power source Capacity at 25 W at 40 W
Power bank (flight limit without approval) 99 Wh ≈ 3.4 h ≈ 2.1 h
Large power bank (airline approval needed) 160 Wh ≈ 5.4 h ≈ 3.4 h
Small power station 300 Wh ≈ 10 h ≈ 6.4 h
Medium power station 1,000 Wh ≈ 34 h ≈ 21 h

Calculated at 85 % efficiency, without start-up peaks or snow melt. In the cold, usable capacity drops further.

Example: how much power do you need per day?

Instead of hours you can think in watt-hours per day. An example with openly stated assumptions:

Assume 4 hours of work a day with e-mail and video calls, 30 W average

4 h × 30 W = 120 Wh consumption

120 Wh ÷ 0.85 efficiency ≈ 141 Wh battery capacity per day

That’s more than one power bank at the 100 Wh flight limit. For such a workday you need two power banks, access to a socket for recharging, or a power station. The Mini is most efficient when you switch it on deliberately rather than running it all day. But remember: each start-up takes a few minutes and briefly needs more power. Try the power calculator.

12 volts in car and camper

In a vehicle you can connect the Mini directly to the on-board supply with a 12 V cable – its input accepts 12–48 V. Make sure cables are adequately sized and properly fused, as 40–60 W at 12 V means several amps. Long, thin cables cause voltage drop and the Mini may not start reliably. For fixed installations in a camper or boat a specialist workshop is the safe choice. More: Starlink Mini in a camper – mounting, 12-volt supply, use on the move.

Power banks on planes

Strict rules apply to lithium batteries in air travel: power banks go in hand luggage, not checked bags. Up to 100 Wh they’re usually allowed without approval, between 100 and 160 Wh only with the airline’s consent (usually at most two), above that not at all. Many airlines have recently tightened their rules: at the Lufthansa Group (which includes Austrian Airlines) power banks may neither be used nor charged on board since 15 January 2026, at most two are allowed, and they may not go in the overhead bin. Check your airline’s terms before every flight. Power stations with several hundred watt-hours are practically never allowed – they’re for campers, boats and cars.

Power station: for campers, boats and longer stays

If you stay longer somewhere without reliable power, a power station with a USB-C PD output (100 W) or 12 V output is the more convenient solution. Power the Mini directly with DC (USB-C PD or 12 V cable) rather than via the 230 V outlet and the original power supply – every extra conversion costs energy.

Solar: realistic expectations

A solar panel only delivers its rated power under ideal conditions. Clouds, low sun, heat, shade and the wrong angle reduce yield considerably. For planning, rely on what you’ve measured at your destination rather than the label on the panel. Rule of thumb: for a 30 W Mini to run several hours a day and recharge the battery, you need considerably more panel power than 30 W.

A simple estimate: daily need in Wh ÷ peak sun hours = required panel power. With the example above (141 Wh per day) and 4 peak hours that’s about 35 W – without any reserve for clouds, shade or charging losses. In practice you plan for a multiple of that, and at northern latitudes in winter solar provides hardly any usable power.

Cold, heat, sand

  • Cold: the Mini is specified down to −30 °C, but batteries lose capacity in the cold. Many LiFePO4 batteries must not be charged below 0 °C – follow manufacturer guidance. Snow melt increases consumption.
  • Heat: the datasheet states up to 50 °C. Keep power banks and power stations out of direct sun.
  • Sand and water: IP67 only applies with cables plugged in. Keep connectors dry and free of sand.

Sockets in your accommodation: what to watch

Even where accommodation has power, it’s often unreliable in remote places: outages, voltage fluctuations, generator power at set hours. A few simple rules help:

  • Check input voltage: every power supply states the range it accepts (e.g. „100–240 V“). Only then does it work in countries with different mains voltage.
  • Bring the right travel adapter for sockets at your destination.
  • Plan a buffer: a charged power bank bridges outages so the important call doesn’t drop.
  • Charge when power is available: with generator power, charge every battery during those hours.

Caring for and storing batteries

Lithium batteries last longer if they aren’t stored permanently full or completely empty and aren’t exposed to great heat. For longer breaks between trips many manufacturers recommend a medium state of charge. Read your manufacturer’s guidance – it varies by cell chemistry.

Our recommendation by trip type

Air travel, a few hours online per day Power bank up to 100 Wh with 100 W USB-C PD Airline rules, 5 A cable
Accommodation with (unreliable) power Power supply plus power bank as buffer 100–240 V input, travel adapter
Car and camper 12 V cable directly on the vehicle supply Cable size, fusing
Longer stays off-grid Power station, possibly with solar Capacity per daily need, plan solar generously

FAQ

Will a normal laptop charger run the Mini?

Only if it delivers 100 W at 20 V/5 A on USB-C and you use a 5 A cable plus the right adapter. Many laptop chargers deliver 65 W – not enough.

Can I run the Mini from a car’s USB port?

Usually not – built-in USB ports deliver far less than 100 W. Use a 12 V cable or a 100 W USB-C PD car charger.

How long does a 1,000 Wh power station last?

On paper about 21–34 hours at 25–40 W and 85 % efficiency – without other devices.
