It is half past four on a Tuesday morning at Perth Domestic. The line at gate 12 is moving toward a Dash 8 bound for one of the iron ore strips up in the Pilbara, and almost every bag rolling through the scanner looks identical: a black hard-case carry-on, a backpack, a battered hi-vis shirt folded on top. What is inside those bags has changed a lot over the last two years, though. The reading material is on a tablet. The site paperwork is in a phone. And tucked between the steel-cap boots and the spare socks, more and more of those carry-ons now hold a slim white Starlink Mini panel and a small black battery to keep it running between the donga and the drill pad.
That last item is where things get interesting, because the airlines have a hard rule about what kind of battery you are allowed to bring on board. Get it wrong and the gate agent will pull your kit, hand it back at the bottom of the airbridge, and tell you to check it through as cargo on the next flight. Get it right and your power bank rides in the overhead locker beside you all the way to site. The whole game is settled by a single number printed on the side of the battery — its watt-hour rating — and it is the reason the PeakDo LinkPower 2 at exactly 99Wh has quietly become the default battery for Australians who fly to remote work with their own connectivity kit.
The 100Wh airline rule, explained without the jargon
The Civil Aviation Safety Authority in Australia follows the same lithium battery limits as the rest of the world through the International Air Transport Association dangerous goods rules. Those limits exist because a lithium-ion cell that vents in flight is a serious problem, and the bigger the cell, the bigger the problem. So the rules sort batteries into three bands by how much energy they store, measured in watt-hours, and each band has its own carry-on rules.
The first band is anything 100Wh or smaller. These can travel in carry-on baggage in any reasonable quantity for personal use, no airline approval required, no paperwork. Phones, laptops, cameras and most personal power banks fit comfortably in this band. The second band is 100Wh to 160Wh. Those need airline approval before you fly, you are limited to two spare batteries, and you have to declare them at check-in. The third band is anything over 160Wh, and these are simply not permitted in passenger aircraft cabins at all — they need to travel as cargo with formal dangerous goods documentation.
Why 99Wh is the sweet spot, not 100Wh
In theory a 100Wh battery is fine to carry on. In practice, manufacturers leave a small safety margin under that number so a gate agent never has a reason to pause when they look at the label. 99Wh sits just below the line with room to spare. The LinkPower 2 was designed against exactly this constraint — the brief was a battery that could keep a Starlink Mini running for hours in the field without ever giving a check-in clerk a reason to stop you walking onto a regional turboprop.
The difference matters when you are running late, the queue is long and the agent is having a hard day. A battery printed clearly with 99Wh goes through without comment. A battery printed with 100Wh might invite a closer look at the spec sheet, an explanation, a check with a supervisor. That is the kind of friction nobody wants at half past four in the morning with a tight connection to make.
What the rules look like in the real world
Most of the major Australian carriers — Qantas, Virgin, Rex, Alliance, Skippers — publish the same numbers in their dangerous goods guides. Cabin-allowed up to 100Wh, conditional 100Wh to 160Wh with approval, prohibited above. The international long-haul carriers you might connect through on the way back from a Singapore-based rotation use the same IATA rule set. There is no airline anywhere in the world where a 99Wh battery is treated as anything other than ordinary carry-on luggage.
Almost every camping power station on the shelf at the big-box stores is over 250Wh. None of those will fit in your overhead locker without a fight. The LinkPower 2 is one of the very few Starlink-grade batteries you can hand to a gate agent and watch them wave you straight through.
Why most camping power stations fail the carry-on test
If you have ever shopped for portable power for camping or off-grid work, you have seen the popular brands — Bluetti, Jackery, EcoFlow, Goal Zero. Their entry-level units typically start at 250Wh and climb fast from there. A common mid-range unit sits around 700Wh, and the flagships are well over 1,000Wh. These are excellent products for what they are designed to do: keep a fridge cold at a caravan park, run a CPAP at base camp, charge a power tool battery overnight at a remote build.
They are also, every single one of them, far too big to bring on board an aircraft. A 250Wh unit is two and a half times the carry-on limit. A 1,000Wh unit is more than six times above the absolute ceiling for any cabin anywhere in the world. The only way these batteries travel by air is in dedicated freight, which means paperwork, lead time, and a much higher chance of damage in handling.
What it actually means to check the battery as cargo
For a fly-in fly-out worker doing a one-week-on one-week-off rotation, putting a power station into checked baggage is not really an option either. Most airlines explicitly prohibit lithium-ion batteries above 100Wh from checked baggage because of the fire risk in the cargo hold — the same vent-in-flight problem, just with no cabin crew nearby to deal with it. Bluetti, Jackery and the rest all say plainly on their support pages: their products are not to be checked.
That leaves freight. You can ship a power station ahead via Toll, Australia Post StarTrack, or a specialist dangerous-goods courier. It costs real money, it has a transit time of two to five days for remote destinations, and it requires the right packaging and a UN3481 declaration. For a tradie flying in for a five-day shutdown, the maths simply does not work. The battery has to be in the carry-on or it does not come on this trip.
The replacement-on-site problem
The other thing site workers learn quickly is that you cannot just buy a power bank at the remote-town Woolworths. The local IGA in Newman or Karratha or Tennant Creek stocks a few cheap phone power banks and that is it. There is no JB Hi-Fi in the donga camp. If your battery does not make it onto the plane, you are running your Starlink Mini off a hi-lux 12V outlet or a generator extension cord for the whole rotation — assuming either is available where you actually need to work.
What 99Wh actually gets you in the field
The honest answer is about one solid Starlink session, then you top up. A Starlink Mini in active use draws somewhere between 20 and 30 watts depending on signal conditions and how hard it is working. Call it 25W as a sensible field average. At 99Wh nameplate, allowing for the conversion losses every battery has when stepping voltage up and down, the LinkPower 2 will keep a Mini running flat-out for about three and a half hours.
That number sounds modest until you think about how you actually use the kit. Very few people sit on a Starlink Mini for a continuous three and a half hours of streaming. The realistic pattern is a 20-minute video call with the home office, a 15-minute file sync of the day’s drill logs, a few quick weather and email pulls, then the panel sits on standby for the rest of the shift. Cycled like that, 99Wh comfortably covers a full working day, with capacity left over for the phone, a head torch and a Bluetooth speaker through the USB-C output.
When you need to stretch the runtime further
The LinkPower 2 has two inputs as well as outputs — a USB-C PD port and a DC input. That means once you are on site, you can top up in the back of the ute on the drive between pads, plug into a wall socket in the donga, or chain it to a folding solar blanket for the lunch break. None of those options require flying with anything bigger than the 99Wh bank itself.
For workers who genuinely need multi-day standalone power — running a remote base camp for a week with no vehicle or mains access — the LinkPower 2 is not the right tool on its own. That is where you pair it with a larger PeakDo LinkPower 1 base station that gets driven or freighted to site, with the LinkPower 2 as the carry-on companion that handles the in-transit and post-shift work.
The other things the same battery runs
A side benefit nobody talks about: a 99Wh PD-capable bank is also enough to fully charge a modern work phone three or four times, top up a tablet, run a CPAP for a few hours through a 12V inverter, or recharge a hand-held UHF radio. The same battery that keeps the Mini alive between the airport and the work site is also a useful piece of personal kit during the rest of the rotation, which is more than you can say about the larger camping power stations sitting in storage back at the depot.
Where this matters most for Australian workers
The FIFO and tradie cohorts that travel to remote work share a few hard problems. Mobile coverage is patchy or absent from the moment they step off the regional aircraft. Site internet, when it exists, is often shared, throttled, or down. Personal accommodation in a donga or a contractor cabin rarely has a fast, reliable connection. The contract terms increasingly require photographic evidence, GPS logs, daily compliance forms, mental health check-ins and family video calls — all things that need bandwidth and uptime, not whenever-the-tower-feels-like-it 3G.
Bringing a Starlink Mini and a flight-legal battery into the carry-on solves the whole stack. The Mini puts down 100Mbps-class connectivity wherever it can see the sky. The 99Wh battery means the Mini works even when the generator is off at 9 PM, the mains is out, or you are between two work locations with no power at either end. It is a kit pattern that has spread fast across iron ore, gold, lithium, gas, infrastructure builds and remote agriculture over the last 18 months, and the binding constraint on adoption has consistently been whether the battery can come on the plane.
Practical site scenarios where the carry-on bank earns its keep
A few patterns come up again and again in feedback from the workforce. Site office without mains power on a fresh greenfield build, where the first weeks before a generator hook-up still need daily compliance uploads. Accommodation donga during a regional outage, when the camp WiFi goes down at exactly the time the family expects a video call. Drive time between two work locations in the back of a crew bus, when a quick file pull or weather check has to happen before arrival. After-hours comms when the camp generator cuts at 10 PM and the only way to call home is to step outside with the Starlink Mini and a charged-up bank. None of these scenarios are exotic. They are the boring Tuesday-night reality of remote rotation work, and they are the reason a flight-legal battery is now treated as part of the standard kit rather than an optional extra.
Honest limitations worth knowing
A few things to put on the table. The LinkPower 2 is not a substitute for a permanent off-grid power system at a fixed base camp — for that you want a deep-cycle battery bank, a charge controller and a couple of hundred watts of solar, not a portable hand-carried bank. The 99Wh capacity is what makes it carry-on legal, and the same thing limits how many hours of pure standalone runtime it gives you.
It is also worth noting the LinkPower 2 ships from Australian stock, which means quick delivery for domestic orders, but international shipping of lithium batteries has its own restrictions that apply at the courier level. If you are travelling internationally and need to take the bank with you, that part is still on the airline rules above — carrying it in cabin baggage is fine, putting it in checked is not, and the same 100Wh ceiling applies on every leg of the trip.
FAQ
Is the LinkPower 2 actually allowed on Australian domestic flights without checking in advance?
Yes. At 99Wh it sits inside the standard CASA and IATA limit of 100Wh for personal lithium-ion batteries carried in cabin baggage. You do not need airline approval, you do not need to declare it at check-in, and there is no quantity limit for reasonable personal use. The same rule applies on every major Australian carrier including Qantas, Virgin Australia, Rex, Alliance and Skippers.
How long will it actually run a Starlink Mini in real use?
About three and a half hours of continuous flat-out streaming, or roughly a full working day in normal cycled use where the Mini is active for calls and syncs but idle for long stretches in between. If you pair the LinkPower 2 with a folding solar blanket or top up from a vehicle on the drive between sites, you can extend that effectively indefinitely during daylight hours.
Can I also use the LinkPower 2 for things other than the Starlink Mini?
Yes. It has both a USB-C PD output and a DC output, so the same battery will charge a laptop, a phone, a tablet, a UHF handheld, a head torch or anything else that takes a standard USB-C charger. Many users carry it as a general-purpose travel battery, with the Starlink Mini as just one of several devices it powers across a week-long rotation.
Closing
If you fly to remote work in Australia, the battery you can carry on the plane is the battery that matters. A 1,000Wh power station that lives in checked baggage cannot be checked. A 250Wh unit that needs freight ahead is too slow and too expensive for a five-day shutdown. A 99Wh battery that goes in the carry-on and stays with you from the airport gate to the donga to the drill pad is the option that actually works week after week.
The PeakDo LinkPower 2 is stocked at Outcamp with Australia-wide shipping, designed for exactly this carry-on workflow, and built to keep a Starlink Mini running through the parts of a rotation where everything else loses signal.
