The Starlink Mini has no built-in battery, but it runs on 12V DC, and that means the tool batteries in your ute can power it directly. The Mini draws only 20 to 40W and accepts 12 to 48V DC input, so a ZED 12V adapter and a 1m Starlink Mini to Anderson cable run it with no inverter, no generator and no heavy power station. Click in a charged Milwaukee, Makita or DeWALT battery, plug in the cable, point the dish at the sky and you are online. Expect 2 to 4 hours from a single 5 to 6Ah battery, and more from bigger packs or the dual-battery Middle Man. Here is the full setup.

Does the Starlink Mini have a built-in battery?
No. The Starlink Mini has no internal battery at all. Cut its power and it drops offline, then reboots when power returns. Starlink sells it this way deliberately: it keeps the dish light, but it means the Mini always needs a constant DC supply.
That supply does not have to be a $1,000 power station. The 18V batteries already sitting in your drill kit hold plenty of energy for a work day's internet. A ZED adapter regulates them to a clean, steady 12V output, which is exactly what the Mini wants.
What voltage does Starlink Mini need?
- Accepts 12 to 48V DC input
- Average running load: 20 to 40W, typically about 30W in the field
- Needs the supply to hold 13.3V or better under load, or it can drop out
That last number is the one cheap setups get wrong. A raw battery or a long skinny cable sags under load and the Mini reboots. ZED adapters hold 13.5V under load, and with the 1m cable the Mini sees 13.3V and above the whole time. We measured it on the bench, not in a brochure.
What you need to run Starlink Mini from a tool battery
Two things, plus the battery you already own:
- A ZED 12V battery adapter built for your battery brand. Pick your platform guide: Milwaukee, Makita or DeWALT.
- A ZED Starlink Mini to Anderson cable, which plugs straight between the adapter's Anderson output and the Mini's power port.
Genuine 50A Anderson plug with dust cover, straight into the Mini's power port. No splicing, no stacked adaptors.
Any of the three ZED kits runs the Mini. Same regulated output, different form factors:
| Kit | Output | Batteries | Best for | Price |
|---|---|---|---|---|
| Middle Man | 12V / 10A | Two | Longest runtime, swap batteries without dropping offline | $349 |
| Power Plate | 12V / 5A | One | Portable power plus a built-in LED flood light | $279 |
| Battle Station | 12V / 5A | One | Fixed install in the ute, van or trailer | $198 |
12V / 10A and runs two batteries at once, so there is twice the capacity on board and the Mini stays online through battery swaps.
Which cable length should I get?
Off a ZED adapter: the 1m, every time. This is counterintuitive, so here is the why. Every metre of cable drops voltage under load. The Mini needs 13.3V or better, and the short 1m run is what keeps it there. A longer cable wastes power, pulls extra current and can cause dropouts.
| Cable | Use it for |
|---|---|
| 1m Anderson | ZED tool-battery adapters (12V). Holds 13.3V+ under load. |
| 2m / 3m Anderson | 24V and 48V vehicle, truck and solar setups, where the higher voltage has headroom to absorb the drop. |
| 5m cigarette-plug cable | 24V systems ONLY. Not compatible with any ZED adapter. |
General rule: keep the cable as short as the reach allows.
How to set up Starlink Mini on a tool battery
- Mount your ZED adapter. Strap it, hook it or fix it in place. The mounting guide covers the options.
- Click in your tool battery. The adapter regulates it to a steady 12V output.
- Connect the 1m Starlink cable. Anderson plug into the adapter, power plug into the Mini.
- Place the dish with a clear view of the sky.
- Turn it on. Internet anywhere.
How long will Starlink Mini run on a tool battery?
Runtime comes down to amp-hours, weather and how hard the dish is working. Real-world figures from our own use:
| Battery on the adapter | Approximate runtime |
|---|---|
| One 5 to 6Ah battery (the size most tradies own) | 2 to 4 hours |
| One large battery (around 10Ah) | 6 to 7 hours |
| Two batteries in the Middle Man | Twice the capacity on board, and you can swap one pack while the other keeps the Mini online |
Two easy wins: turn snow melt off (you are in Australia) and keep spare packs on the charger. Location, weather and battery age all move the numbers, which is why we quote ranges, not fantasy figures.

Why tool batteries beat a power station for the Mini
- No inverter. The Mini runs on DC. Converting battery DC to 240V AC and back to DC just wastes power.
- No generator noise, fuel or servicing.
- Lighter and cheaper than a power station you bought for one job.
- Batteries you already own, charged by the charger you already own.
- Aussie-made kit: genuine Anderson plugs, Omron relays, polycarbonate housings, assembled and tested in Queensland.
It is the same thinking as turning a tool battery into a portable power station: the batteries in your kit are a power supply, put them to work.

Frequently asked questions
Does Starlink Mini work on 12V?
Yes. The Mini accepts 12 to 48V DC input. The catch is that the supply must hold 13.3V or better under load, or the dish can drop out. ZED adapters hold 13.5V under load, which is why they run the Mini reliably where raw batteries and cheap droppers sag.
Does the Starlink Mini have a battery inside?
No. There is no internal battery, so the Mini needs constant DC power and goes offline the moment supply is cut. Pairing it with tool batteries on a ZED adapter is the lightest way to keep it fed off-grid.
How long will Starlink Mini run on a 5 or 6Ah battery?
Between 2 and 4 hours, depending on weather, location and battery age. A large battery around 10Ah runs 6 to 7 hours. Turn snow melt off to stretch it further.
Which cable do I need for a ZED adapter?
The 1m Starlink Mini to Anderson cable. The short run keeps voltage above 13.3V under load. The 2m and 3m lengths are for 24V+ vehicle and solar setups, and the 5m cigarette-plug cable is 24V only, so it does not suit any ZED adapter.
Do I need an inverter for Starlink Mini?
No. The Mini runs on DC, so a regulated 12V adapter is all you need. An inverter only adds weight, noise and wasted power.
Will running the Mini flatten my tool battery?
ZED Milwaukee and DeWALT adapters have the ZED Smart LVD, which cuts the output at 14.0V under load and then sits at an ultra-low idle, so a forgotten battery is not run into the ground. Makita packs have their own internal disconnect and ZED Makita adapters rely on that. Note the adapters power the Mini only, they never charge the battery.
