The Starlink Mini changed off-grid internet because it sips power. At roughly 25-40W it draws less than a laptop charger, weighs just 2.43 lbs, and accepts a wide 12-48V DC input — which means you can run it straight off a battery without ever touching an AC outlet. That single fact is the key to powering it efficiently in a van, a tent, or a remote basecamp.
This is the technical power authority for the Mini. We'll cover exactly what it needs, rank every realistic off-grid power source, and give you the run-time math so you can size a battery or solar setup with confidence instead of guessing. If you want the broader camping context first, start with our Starlink Mini for camping guide, then come back here to nail down the power.
Starlink Mini power requirements
The Mini ships with an AC wall adapter, but that adapter is the worst way to power it off-grid. Here's what actually matters.
Voltage: The Mini accepts 12-48V DC through a barrel jack. That wide range is a gift — it runs directly off a 12V house battery, a car cigarette socket, 20V USB-C Power Delivery, or a 48V system without any conversion gymnastics.
Power draw: Expect ~25-40W. We use ~28W as the typical figure for sizing and ~40W as the peak/cold figure. The dish is electronically steered (no moving motor), so draw stays low and steady once it's locked on.
Daily energy: Run it 24 hours and you'll consume roughly 600-960 Wh per day. Most people don't run it around the clock, but plan for the full day if it's your only connection.
Why DC beats AC and inverters
If you power the Mini from a battery through an AC inverter and back into the wall adapter, you pay two conversion taxes: the inverter (DC→AC, ~85-90% efficient) and the adapter (AC→DC, ~85-90% efficient). Stacked, you can lose 20-25% of your stored energy as heat before a single watt reaches the dish.
Feed the Mini DC directly and you skip both. A simple 12V-to-barrel cable or a 12V-to-48V converter delivers power with minimal loss. On a small battery, that difference is the gap between 7 hours and 9 hours of runtime. For a full DC build, see our Starlink RV 12V power setup guide.
The off-grid power options, ranked
Here's every realistic way to power the Mini, ranked by how foolproof they are off-grid:
- Portable power station — Plug-and-play, has a 12V output or AC outlet, built-in battery and (often) solar input. Easiest by far.
- DC from your vehicle / 12V socket — Free power while driving or idling; needs a 12V-to-barrel cable and ideally a 12V-to-48V converter for stable voltage.
- USB-C PD power bank + trigger cable — Ultralight and pocketable for short trips; runs the Mini on 20V with the right adapter cable.
- Hardwired battery bank — A LiFePO4 battery wired into your rig for serious capacity; pair with a Victron BMV-712 battery monitor so you always know your state of charge.
- Solar — Not a standalone source (the sun sets), but the multiplier that turns any of the above into indefinite off-grid internet.
Most builds combine two: a battery (station or bank) for storage and solar to refill it. The sections below size each one.
Run-time math: how long will your battery last
The formula is simple. Take the battery's watt-hours, multiply by a ~85% derating factor (real-world inverter loss, voltage conversion, and the fact you should never drain a battery to zero), then divide by the Mini's average draw:
Usable hours = (Battery Wh × 0.85) ÷ 28W
That 0.85 is conservative and keeps your estimates honest. Here's the math run for common battery sizes at ~28W:
| Battery capacity | × 0.85 usable | ÷ 28W draw | Run-time at ~28W |
|---|---|---|---|
| ~90 Wh (25,000 mAh USB-C bank) | ~77 Wh | ~2.7 h | ~2.5-3 hours |
| 288 Wh (Jackery 300 Plus) | ~245 Wh | ~8.7 h | ~8-9 hours |
| 768 Wh (EcoFlow RIVER 2 Pro) | ~653 Wh | ~23.3 h | ~22-24 hours |
| 1,152 Wh (Bluetti AC180) | ~979 Wh | ~35 h | ~33-35 hours |
How to use this: Decide how many hours per day you actually need internet, multiply by 28W, and that's your daily Wh target. Need 10 hours a day? That's ~280 Wh — a 288 Wh station barely covers one day with nothing to spare, which is exactly why solar matters for multi-day trips.
Choosing a power station
A portable power station is the simplest entry point: charge it at home, run the Mini off its 12V port or AC outlet, and recharge it from solar in the field. Three tiers cover most needs.
Weekend tier — ~288 Wh
The Jackery Explorer 300 Plus (288 Wh) is light enough to carry and gets you ~8-9 hours of Mini runtime. Perfect for an overnight or a day trip where you're not online constantly. Pair it with a small solar panel and you can stretch a weekend.
All-day tier — ~768 Wh
The EcoFlow RIVER 2 Pro (768 Wh) delivers ~22-24 hours — essentially a full day of continuous use, or two to three days of normal on-and-off browsing. This is the sweet spot for most van and camping setups.
Basecamp tier — 1,000+ Wh
The Bluetti AC180 (1,152 Wh) runs the Mini ~33-35 hours and has the headroom to also charge laptops, run a fan, or power a fridge. For a stationary basecamp or a rig where Starlink shares the battery with everything else, go big. Our best portable power stations for Starlink RV roundup compares these in detail.
USB-C PD power banks and the trigger-cable approach
For ultralight trips, a USB-C PD power bank is the smallest way to power the Mini. The trick is the connector.
The Mini wants 12-48V on a barrel jack. A USB-C PD bank negotiates voltages like 5V, 9V, 15V, and 20V. To bridge them you use a USB-C to barrel trigger cable — it "triggers" the bank to output 20V and feeds it to the Mini's jack. Make sure the trigger cable is set/rated for 20V and that your bank supports at least 60W PD.
Run-time reality check: A 25,000 mAh bank is about 90 Wh, which after derating is ~2.5-3 hours at 28W. Great for a quick check-in or a hike, not for a workday. Carry two banks or step up to a power station if you need more.
Solar sizing for all-day operation
Solar is what turns "a few hours" into "indefinitely." The Mini's ~28W draw is tiny compared to what a panel produces.
A single ~200W solar panel in good sun produces several times the Mini's draw — it powers the dish and refills your battery at the same time. Practically:
- One ~200W panel keeps the Mini running through daylight and tops off a 288-768 Wh battery for overnight use.
- The EcoFlow 220W bifacial solar panel pairs natively with EcoFlow stations and grabs extra light off its back side.
- The Jackery SolarSaga 200W folds flat and plugs straight into Jackery stations.
Even on a cloudy day, a 200W panel typically clears the Mini's continuous draw. For mounting angles, MPPT controllers, and wiring a permanent array, read our Starlink RV solar panel setup guide.
The cold-weather power penalty
Cold changes the math in two ways, and both cost you runtime.
The Mini draws more. In cold conditions the dish works harder to stay clear and warm, pushing draw toward the ~40W end of the range. At 40W, that 768 Wh station drops from ~23 hours to roughly ~16 hours. Always size for peak draw if you camp in winter.
Batteries hold less. Lithium batteries lose capacity in the cold and many LiFePO4 batteries refuse to charge below freezing without a heater. A station rated 768 Wh may deliver noticeably less at 20°F. Keep batteries insulated, store the power station inside, and oversize your capacity by 20-30% for cold trips.

Frequently asked questions
How many watts does the Starlink Mini use? Roughly 25-40W. Plan around ~28W typical and budget ~40W for peak or cold weather — about 600-960 Wh over 24 hours.
Can you run the Starlink Mini on a power bank? Yes. Its 12-48V barrel input means a 20V USB-C PD bank plus a trigger cable runs it directly. A ~90 Wh bank gives ~2.5-3 hours.
How long will a power station run it? At ~28W with 85% derating: 288 Wh ≈ 8-9 h, 768 Wh ≈ 22-24 h, 1,152 Wh ≈ 33-35 h.
Can the Mini run on solar? Yes — a ~200W panel far exceeds its draw, running the dish all day and topping the battery.
What voltage does the Mini need? A wide 12-48V DC range through the barrel jack, so it runs off 12V batteries, car sockets, and 20V USB-C without an inverter.
