What the Starlink Mini actually draws

SpaceX's spec sheet says 20–40W. Our real-world testing across 6 months of vanlife use:

  • Idle / standby: 18-22W
  • Active streaming / video calls: 30-40W
  • Cold start (first 2 minutes): brief peaks to 60W
  • 24-hour daily average: ~28W

That's ~672 Wh per day of continuous use. Plan your power around that number, not the marketing number.

Three setups, three budgets

Setup 1: Weekend warrior — power bank only ($160)

If you're using Starlink for weekend trips, a 24,000mAh power bank with 12V output is enough.

Runtime: ~3 hours of active use, ~5 hours idle.

Setup 2: Full vanlife — power station + solar ($1,600)

Runtime: ~40 hours of Starlink-only use. With 100W solar, you can run Starlink + a fridge indefinitely.

Setup 3: Serious full-time — bigger station + more solar ($3,000)

Runtime: ~68 hours of Starlink-only use. With 200W solar, you'll stay charged indefinitely.

Do you need solar?

  • Starlink Mini draws ~672 Wh/day at typical use
  • 100W solar panel produces 400-600 Wh/day in temperate sun
  • 200W solar panel produces 800-1,200 Wh/day in temperate sun

So 100W = net-deficit on cloudy days. 200W = net-positive most days.

Wiring it: 12V barrel cable matters

Plug into the 12V barrel directly when possible. You'll get ~95% efficiency vs ~85% through the AC inverter.

Mounting matters for power efficiency

A well-mounted dish with clear sky idles at ~22W. A poorly mounted dish under tree cover hunts for signal and draws 50W+ continuously.

Frequently asked questions

How many amp hours do I need to run Starlink Mini in a van?

Plan for around 60Ah at 12V per day of continuous use (roughly 672Wh). A 1000–1300Wh LiFePO4 station will run the dish for 1.5–2 days without recharge; a 2000Wh station gets you close to 3 days.

MPPT or PWM — which charge controller do I need for solar?

Use MPPT for any panel above 100W or any battery above 12V nominal — you'll harvest 20–30% more energy than PWM, especially in partial shade. PWM is only worth it for tiny sub-100W trickle-charge setups.

Can I just power Starlink Mini from my car's starter battery?

Only briefly. The dish will drain a starter battery to non-start levels in 2–3 hours because starter batteries aren't designed for deep discharge. Use a deep-cycle LiFePO4 power station or a dedicated house battery instead.

Does the Starlink Mini have a built-in battery?

No. The Mini must be powered continuously from an external source — 12V DC barrel, USB-C PD at 100W, or an AC adapter. Any interruption resets the dish and forces a fresh cold-start (60W peak for 2 minutes).

Will Starlink Mini run on solar alone with no battery?

No. Solar output is too variable — clouds, angle changes, and even a hand shadow will drop voltage below the dish's threshold. Always wire solar → charge controller → battery → dish.

Bottom line: Most vanlifers overspec their power. A 1000-1300 Wh LiFePO4 station + 100-200W solar handles 95% of real-world use cases.
