Waterproof 12v to 30v Starlink Mini Booster
Forget flimsy adapters — this is the ultimate set-and-forget power solution for permanent Starlink Mini installations in rain, floods, coastal salt spray, and harsh off-grid environments.
This Waterproof 12v to 30v Booster delivers stable power to your Starlink Mini, even with weak battery voltage, and is built to survive tough outdoor conditions. It includes a pre-wired 10A fuse and bare tails for hardwiring to your vehicle, roof rack, boat, or off-grid cabin.
Don’t mess around with overcomplicated setups you read about online. If you have a 12v battery, hook this up to it and your Starlink Mini will work uninterrupted. If extending the cables, please use decent size wires.
⭐ Essential benefits
• Permanent waterproof power – IP68-rated housing and sealed cables for roof racks, boats, and flood-prone installs.
• 9–16v input range – handles weak or overcharged 12v batteries and solar systems.
• Stable 30v output – optimised for Starlink Mini’s needs with reliable voltage delivery.
• 10A fuse protection – pre-wired safety against surges and shorts.
• Hardwire-ready setup – bare input tails for custom setups, Anderson plugs, cable extensions, or direct battery connection.
• Rugged outdoor design – dustproof, shockproof, and submersible up to 1.5m.
⚙️ Functionality
This booster connects directly to your 12v battery system using the bare input tails, then converts the input voltage into a stable 30v DC output for your Starlink Mini.
It is designed for permanent installs where you want a rugged, waterproof, and low-maintenance power solution. Once installed, connect your Starlink Mini cable, route the wiring properly, and you’re ready to go.
Not looking for permanent? For a portable plug-and-play option, check out our 12v Starlink Mini Plug & Play Adapter or the Anderson plug version.

Yes. It's purpose-built for the Starlink Mini and outputs exactly 30V, the same spec Starlink recommends. No tinkering or guesswork, just plug it in and you're online. It is not for the Gen 2 or Gen 3 dish, which have different power requirements.
Yes, It comes with a 2.5m Starlink Cable. Perfect for almost every install setup.
No. The boosting is built in. As your battery voltage rises and falls through the day, the adapter holds a steady 30V to your Mini, so you don't get the under-voltage dropouts that plague straight 12V setups.
It draws around 24W on average, with headroom up to 100W for the Mini's peak demands like booting up or heavy weather. That's a fraction of what an inverter setup wastes doing the same job.
No, it only draws what the Mini needs. At roughly 24W average, a 100Ah lithium battery will run a Starlink Mini for well over a day. AGM batteries won't stretch as far, since you can only safely use around half their capacity, so expect noticeably less runtime. If hardwiring to your vehicle's main battery, an isolation switch is a necessity.
The power supply itself is rated IP68. As long as you do a decent job wiring it up, its all happy days, throw anything at it!
Easy! If you can connect two wires to a battery, you can install this. The booster comes with a pre-wired 10A fuse and 2.5m of UV-resistant cable, so it's just red to positive, black to negative, then route the DC plug to your Mini. No cutting into your Starlink cable, no configuration. Most installs take under 30 minutes.
Yes, as long as it has a 12V DC output, you're good. The booster accepts anything from 9–16V, so a power station's direct 12v output or a battery box's Anderson plug will run it no problem. If your battery box has Anderson outputs, grab the Anderson Style version of this booster and it's literally plug in and go, no wiring at all. Just don't run it off the power station's AC outlet through an inverter; that wastes battery for no reason when the 12V output does the job directly.
Yes. The 9 to 16V input range handles the voltage swing you get while the alternator is charging, so the Mini stays online on the move.
This version is built around the cig plug for true plug-and-play use. If you want a permanent wired install, go for the Anderson plug version of this unit, or step up to the K2 Pro for a fully mounted setup with wireless remote switching.
No, Check out our Treklo K2 Units if you want the real deal, top of the range unit.
Nah. This one's a set-and-forget unit. It stays powered whenever your battery's hooked up (or flick it via your isolation switch). If you want the real deal with remote on/off, have a squiz at our Treklo K2 top-of-the-range unit with a wireless remote, so you can fire up your Mini without crawling out of the swag/bed.
1 year warranty, backed by us here in Geelong. If something goes wrong you're dealing with real people locally, not an overseas ticket queue.
Order before 3pm AEST for same day dispatch from Geelong. Free express shipping Australia wide on orders over $100, so this unit always ships free. We also deliver to Aus Post parcel lockers and post offices.

Easy to fit, seems to do its job well 👍🏼
M
Does as expected.
A
The cable is good. The little bag of lollies was even better. Cheers.
G
I have installed it and yes there is 30v on the output but yet to connect the mini to it
C
Full time on the road with two kids... The dish stays online now overnight, which it never did before. No more resetting the dish every morning. Nothing has come loose despite the corrugations. Arrived well packed and quicker than the estimate said. Nothing else comes close.!
F
Legends.
S
Two thousand kays in and no issues. Cut my power consumption by around a third. Nothing has come loose despite the corrugations. Wired it in with the supplied leads in less than an hour. Would buy again in a heartbeat.
A
easy to set up for better performance of starlink
T
Really impressed with the build quality. Paired it with 200ah of lithium and it is faultless.
O
Honestly did not expect much. Postage to regional SA was faster than I expected. No voltage drop over the run to the roof.
I
Cannot fault it. Wiring diagram was clear enough for a non sparky. No fuss when I needed to change the delivery address. Cheers to the team for the help.
I
Brilliant bit of kit.
A
My son set it up for me. Very happy customer here.
M
Its as described , but why dont they give you a bit more wire both ends, now I have to have joins
A
Great improvement with the performance of our Starlink
Thanks for the Lollies
Cheers

Quality gear.
I
Went with this over the diy option. Stopped the annoying reboot loop we had every evening. Will be buying again.
L
Our voltage was dropping every night. Had a question before ordering and they came back same day. Consistent output whether the alternator is charging or not. Runs off our portable battery when we are away from the rig. Customer service answered my email within the hour. Small enough that finding a spot was easy. Would like to see a version with a display. No hesitation recommending this.
I
Nothing but good things to say. Wiring diagram was clear enough for a non sparky. The gear ships well packed which I appreciate.
L
Ordered on a whim and glad I did. Instructions were clear and actually made sense. Consistent output whether the alternator is charging or not. Would like to see a version with a display.
P
Cannot fault it. The inline fuse holder is proper automotive grade. Fits neatly in the battery box with room to spare. Cheaper to run than the generator by a mile.
F
Came recommended by the caravan club. Fixed a problem I had wrongly blamed on the dish itself. Top marks.
M
Spent weeks researching this. Runs the dish down to about 11 volts without complaint..
E
This replaced a mess of adapters... Packaging was thoughtful, nothing rattling around. Cheaper to run than the generator by a mile. Cable glands are sealed properly, no dust ingress. The polarity protection saved me when I wired it backwards. Not cheap, that is the only downside. Will be buying again.
F
Was recommended by a bloke at a campsite. Output is clean, no ripple showing on the meter. Five stars easily.
M
Perfect for what we needed. Instructions were clear and actually made sense.
S
Came recommended by the caravan club. Wiring diagram was clear enough for a non sparky. Works off the aux battery without touching the starter. Packaging was thoughtful, nothing rattling around.
C
Perfect for what we needed. Instructions were clear and actually made sense. Packaging was thoughtful, nothing rattling around.
P
Easy transaction, well packaged, and prompt delivery!
Lollies were a nice addition 😋
P
Product exactly as described, fast postage, love the free lolly bag! I’d purchase something again just for the lollie incentive! All in all a great experience so far.

Spent weeks researching this. Cable glands are sealed properly, no dust ingress.
I
Just what the doctor ordered... No fuss when I needed to change the delivery address. The polarity protection saved me when I wired it backwards. Been through a hot summer without any thermal shutdown.
J
Ordered on a whim and glad I did. Quieter than the inverter it replaced, no fan at all. No voltage drop over the run to the roof.
