The Anker 737 is the power bank you buy when the thing that dies isn't your phone but your laptop. Its 140W USB-C output - delivered over the newer Power Delivery 3.1 standard - is enough to charge a 16-inch MacBook Pro or a big Windows ultraportable at close to wall-socket speed, something no 20-30W bank can attempt. The 24,000mAh cell works out to about 86 watt-hours, deliberately under the 100Wh carry-on ceiling, so frequent flyers can take a full laptop recharge on board. Three ports (two USB-C, one USB-A) let a phone and earbuds share the bank, and the little digital display showing live wattage in and out is more useful than it sounds - you can see exactly how fast everything is charging and how long the bank needs at the wall. It's a dense, heavy brick and it costs nearly three INIUs, but nothing matches it for keeping a proper laptop working through a long-haul flight.
UGREEN's flagship bank is for the traveller carrying more than one serious device. Where the Anker 737 pushes 140W down a single cable, the Nexode splits 200W of total output across three ports, so a laptop can charge at full speed while a phone and a tablet share the rest - the difference between queueing your devices and doing them all at once. The 25,000mAh capacity works out to roughly 92 watt-hours, which still clears the 100Wh carry-on line for Australian airlines, though only just; this is about as big as a flight-legal bank sensibly gets. It's correspondingly large and heavy - this one lives in a backpack, not a pocket. At A$119.99, down from over A$200, it's the best-value laptop-class bank on Amazon AU, and the pick for digital nomads, photographers and anyone whose bag holds a laptop, a phone and a camera that all hit zero on the same day.

With more than 30,000 reviews at 4.7 stars, this INIU is the most trusted power bank on Amazon AU, and it earns the top spot on sheer sensibleness. Twenty thousand milliamp hours is the sweet spot for real life - three to four full phone charges once conversion losses are counted - yet INIU has squeezed it into a case closer in footprint to the 10,000mAh banks of a few years ago. The 22.5W output won't trouble a laptop, but it fast-charges phones properly, and the USB-C port works in both directions so the bank itself refills overnight. At roughly 74 watt-hours it sits comfortably under the 100Wh airline limit, so it goes in your carry-on on any Australian domestic or international flight without paperwork. At under A$40 it's the answer to 'which power bank should I buy?' - everything else on this list is here for a more specific job.

Magnetic banks solve the real annoyance of portable charging: the awkward phone-and-brick sandwich dangling from a cable. This UGREEN snaps to the back of any MagSafe-compatible iPhone (iPhone 12 onward) and charges wirelessly while you keep using the phone one-handed - genuinely convenient at an airport gate or on the couch. Be clear-eyed about the trade, though: wireless charging is slower and less efficient than a cable, so when you're in a hurry, plug into the 20W USB-C port instead, which fast-charges iPhones and Android phones alike. The 10,000mAh capacity is good for one to two full charges depending on how much of it goes over the magnet rather than the wire. At A$47.98 - less than half its A$101 list price - it's the affordable way into the magnetic-bank category, and with 18,000-plus reviews it's far better proven than the no-name MagSafe-style banks flooding Amazon.

First, the important distinction: this is not a power bank. The Anker Prime is a mains-powered GaN charging station - it plugs into a wall socket and holds no battery of its own. What it replaces is the tangle of individual chargers colonising your desk and power board. Six ports and 200W of total output mean a laptop, a phone, a tablet, earbuds and a watch can all charge at once from one compact unit occupying a single power point, and gallium nitride electronics keep it efficient and cool while doing it. The 4.7-star average across 3,300 reviews is the equal-best of any product on this list. It's the natural desk partner to any of the banks above: the station keeps everything topped up at home, the bank covers you out the door. At A$94.72, close to half its usual price, it's an easy tidy-up for a crowded setup.

Pros
+ Six ports and 200W total - one unit replaces a drawer of chargers
+ GaN design runs cool and efficient under load

Cons
− Not a battery - useless away from a power point
− More ports than many households will ever fill
− Total output is shared when everything charges at once
Like the Anker station above, this is a wall charger, not a battery - but where the Prime rules the desk, this UGREEN is the one to pack. It's a single GaN brick with four ports and 100W of total output, which is enough to charge a laptop at full speed on its own, or a laptop at reduced speed alongside a phone and earbuds. For travel, that maths matters: one power point in a hotel room - often all you get - now charges everything you're carrying, and the charger itself is barely bigger than some of the standard laptop bricks it replaces. GaN II efficiency keeps heat sensible even under sustained load. At A$62.68 it's the cheapest way to retire three or four separate chargers, and the natural companion to the Anker 737 or Nexode bank for anyone who regularly travels with a laptop. If you only buy one wall charger from this list, buy this one.

The pocket pick. INIU's 10,000mAh unit is the bank you can actually forget is in a jacket pocket or a small bag, and at A$32.99 it's the cheapest product on this list. The surprise is the 45W Power Delivery output - most banks this size top out around 20-22.5W. That means it fast-charges any phone at full speed, and in an emergency it will keep an ultraportable laptop or a Nintendo Switch ticking over too, though at this capacity you're really buying it for phone duty: expect around one and a half to two full charges after conversion losses. Nearly 22,000 reviews at 4.6 stars suggest the reliability matches its bigger sibling at the top of this list. The honest truth about 20,000mAh banks is that many people eventually stop carrying them; this one is light enough that it just lives in the bag permanently. Pair it with the 20K INIU rather than choosing between them.
We researched the power banks and USB-C chargers available on Amazon Australia, evaluating each on real output wattage and charging-standard support (USB Power Delivery and PPS), capacity against weight and size, port count and flexibility, build quality and brand track record, and value at Australian retail prices. Banks were matched to the devices they'll actually charge - phones, tablets or laptops - rather than headline milliamp-hours, and every battery was checked against the 100Wh carry-on limit. Prices are in AUD and refreshed regularly.
Scored 0–10 on Power Output, Capacity & Ports, Portability, Value
A 10,000mAh bank gives roughly one and a half to two full phone charges once conversion losses are counted, and it's the biggest size that genuinely fits in a pocket. A 20,000mAh bank roughly doubles that and suits weekends away or tablet duty, but it lives in a bag rather than a pocket. Beyond 20,000mAh you're into laptop territory - bigger, heavier, and worth it only if you have the devices to feed.
Wattage: What PD and PPS Actually Mean
Output wattage decides what a bank can charge. 20-30W fast-charges any phone; 45-65W handles tablets and lighter laptops; 100W+ charges full-size laptops properly. USB Power Delivery (PD) is the universal fast-charging standard nearly every modern device speaks, and PPS is the refinement that lets Samsung and other Android flagships hit their top charging speeds. If a bank lists PD it will fast-charge iPhones and most Androids; PPS is the bonus to look for if you carry a Galaxy.
Flying with Power Banks in Australia
Power banks must travel in carry-on luggage - never in a checked bag, where a damaged lithium battery can't be reached. Under 100Wh (roughly 27,000mAh) no airline approval is needed, and every bank on this list is under that line. Airlines layer their own rules on top - some cap how many spare batteries you carry, and several now restrict using or charging power banks in-flight - so check your carrier's battery policy before a trip. A bank found in checked luggage can simply be confiscated.
Magnetic Qi2 and MagSafe-Style Banks
Magnetic banks snap to the back of a compatible iPhone (or a phone with a magnetic case) and charge wirelessly while you keep using it - no cable, no phone-and-brick sandwich. The trade-off is speed and efficiency: wireless charging is slower than a cable and wastes more of the bank's capacity as heat. Treat the magnet as the convenience option and the USB-C port as the fast option - the best magnetic banks give you both.
Why One GaN Brick Replaces Several Chargers
Gallium nitride (GaN) electronics switch faster and waste less energy as heat than older silicon designs, so a GaN charger delivers far more wattage from a smaller, cooler brick. The practical upshot: one multi-port GaN charger can fast-charge a laptop, phone and earbuds simultaneously from a single power point, replacing three or four separate chargers on your desk or in your travel bag. Just note that total output is shared - plug in more devices and each gets a smaller slice.
Somewhere in the last few years, everything you carry started charging over USB-C - phone, laptop, earbuds, tablet, e-reader, camera. That's quietly great news, because it means one good power bank or one good wall charger can now do the job of the bag of mismatched bricks and cables most of us still lug around. The hardware has caught up too: gallium nitride (GaN) chargers pack serious wattage into travel-size bricks, and laptop-class power banks that were exotic two years ago are now genuinely affordable.
This list covers the lot. There are pocket-sized banks from about A$33 that live in a jacket pocket, 140W-plus banks that will recharge a full-size laptop mid-flight, a magnetic MagSafe-style bank that snaps to the back of an iPhone - and, because charging doesn't stop at batteries, two GaN wall chargers: a six-port desk station and a four-port travel brick that replaces every charger in your bag.
Every pick is chosen for Australian buyers: all prices are in AUD, every product is available on Amazon AU, and every battery here sits under the 100Wh limit Australian airlines apply to carry-on power banks, so nothing on this list will be stopped at the gate.
Power Banks & Chargers — Frequently Asked Questions
Can I take a power bank on a plane in Australia?+
Yes - but only in carry-on luggage, never in a checked bag. Australian aviation rules require lithium power banks to travel in the cabin, and anything under 100Wh (roughly 27,000mAh) needs no airline approval - every bank on this list is under that line. Airlines add their own rules on top: some cap how many spare batteries you can carry, and several international carriers now restrict actually using or charging power banks in-flight, so check your airline's battery policy before you fly. A power bank found in checked luggage can simply be confiscated.
How many phone charges will I get from a 10,000mAh or 20,000mAh power bank?+
Fewer than the raw numbers suggest - voltage conversion and heat typically eat 30-40% of a bank's rated capacity. As a rule of thumb, a 10,000mAh bank delivers roughly one and a half to two full charges of a modern phone, and a 20,000mAh bank roughly three to four. Phones with bigger batteries sit at the low end of those ranges, and charging wirelessly over a magnetic connection loses more capacity again than charging by cable.
Can a power bank charge a laptop?+
Only if it has enough USB-C Power Delivery output - as a rough floor, 60W or more for genuine charging while you work, and 100W+ to charge a large laptop at proper speed. Most everyday banks top out at 20-45W, which will slow a laptop's discharge at best. On this list, the Anker 737 (140W) and the UGREEN Nexode 200W are built specifically for laptop duty. Check that your laptop charges over USB-C first - some gaming machines only accept their own barrel-plug charger.
Do GaN chargers get hot?+
They get warm under sustained full load - that's normal for any charger - but GaN (gallium nitride) designs run noticeably cooler than the older silicon chargers they replace, because they convert power more efficiently and waste less of it as heat. That efficiency is exactly why a 100W GaN brick can be smaller than the 61W silicon charger many laptops shipped with. If any charger becomes too hot to comfortably touch, unplug it and reduce the number of devices drawing from it.
Will these charge both iPhone and Android?+
Yes. Everything on this list charges over USB-C using the Power Delivery standard, which iPhones (USB-C since the iPhone 15, or via a USB-C-to-Lightning cable before that) and effectively all Android phones support. The one partial exception is the magnetic UGREEN bank: its wireless magnetic attachment is designed for MagSafe iPhones or phones fitted with a magnetic case, but its USB-C port still fast-charges any phone the normal wired way.
