Anker vs Mophie vs Zendure Power Banks 2026 AU: Which Stays Airline-Safe Under 100Wh

Qantas tightened its lithium battery carry-on rule to require passengers to physically carry power banks in the cabin, not stowed above, effective mid-2025, and travellers who miss the 100Wh cutoff still get devices seized at the gate at both Sydney and Melbourne international departures. The rules are federal (CASA and IATA), the enforcement is airline-by-airline, and the practical result is that a 27,650 mAh power bank branded for laptops but voltage-labelled at 3.7 V nominal will pass; a 27,650 mAh unit labelled at 3.85 V nominal calculates to 106 Wh and does not. This guide compares Anker's PowerCore and Prime lines, Mophie's Powerstation Pro range, and Zendure's SuperTank and SuperPack against the 100Wh threshold, and against the port layouts and charging speeds a Sydney or Melbourne international-departure traveller needs on a 10 to 15 hour flight.

The three brands are close on capacity-per-dollar in the sub-100 Wh band. Anker is the volume leader with the widest product depth. Zendure is the port-density and PD-power-delivery specialist. Mophie sits in the Apple-adjacent ecosystem lane with Qi wireless integration on some models. Choosing between them for airline-safe carry-on comes down to laptop charging needs, port layout, and unit weight rather than the Wh rating alone.

Verdict for the Australian long-haul traveller

For a Sydney or Melbourne to Europe traveller who needs to keep an iPhone, an AirPods case, a Kindle, and a MacBook Air or 14-inch MacBook Pro topped up across a 14 to 15 hour segment plus connection, the sharpest airline-safe pick is the Zendure SuperTank (26,800 mAh, 96.5 Wh, 100W USB-C PD in and out, 4 USB-C ports) because the 100W PD rating charges the MacBook cleanly and the port count covers a family or a laptop-plus-phone stack simultaneously. The Anker PowerCore 26800 is the sharpest pick if the traveller has no laptop-charging need because it costs less and the USB-A layout matches most airline seatback ports. The Mophie Powerstation Pro XL is the pick if the traveller wants Qi wireless on a compatible SKU and does not need MacBook Pro laptop supply.

Do not read this as an absolute ranking. Which brand ships the best current SKU depends on the specific model each retailer has in stock and its Wh label as of 2026-08-26.

What is the 100Wh airline limit and how does it map to mAh?

The 100Wh threshold is set by IATA (International Air Transport Association) as the ceiling for lithium-ion power banks and spare batteries permitted in aircraft cabins without airline approval. Australian regulator CASA (Civil Aviation Safety Authority) adopts IATA guidance directly, and Qantas, Virgin Australia, Jetstar, and Rex Airlines all enforce the 100Wh threshold at the gate.

Watt-hours equal ampere-hours multiplied by voltage (Wh = Ah x V). Manufacturers advertise capacity in milliamp-hours (mAh); to convert to Wh, divide mAh by 1,000 and multiply by nominal voltage. The two nominal voltages in wide use are 3.7 V (traditional lithium-ion cells) and 3.85 V (newer high-voltage lithium-ion chemistries).

Which mAh capacities correspond to the 100Wh limit?

At 3.7 V nominal, the 100Wh limit corresponds to 27,027 mAh. A 27,000 mAh power bank at 3.7 V is 99.9 Wh, just under the limit. A 30,000 mAh unit at 3.7 V is 111 Wh, over the limit and cabin-restricted. At 3.85 V nominal, the 100Wh limit corresponds to 25,974 mAh. A 26,800 mAh unit at 3.85 V is 103.2 Wh, over the limit. The label voltage matters as much as the mAh figure.

How does the 160Wh secondary threshold work?

Between 100Wh and 160Wh, IATA rules permit up to 2 spare batteries or power banks per passenger with airline approval, obtained by contacting the airline before travel. Above 160Wh, lithium-ion power banks are not permitted on passenger aircraft. Portable power stations (Anker PowerHouse, EcoFlow River, Jackery Explorer, Zendure SuperBase) typically sit well above 160Wh and are excluded from cabin travel entirely.

What happens if a bank is confiscated at the gate?

Confiscated power banks are typically retained by the airline or airport security and not returned. Travellers can request the Wh calculation be re-verified at the counter if the label shows a lower Wh than the gate agent's estimate, but the process rarely reverses at the boarding gate. The safer path is to verify the Wh printed on-device before travel.

What Anker power banks are airline-safe for Australian travellers in 2026?

Anker publishes on-device Wh labels for its PowerCore, Prime, and 737 product lines, which makes gate-agent verification straightforward. The following models sit under 100Wh and are cabin-permitted as of 2026-08-26.

Anker PowerCore 26800

The Anker PowerCore 26800 (26,800 mAh at 3.6 V nominal, labelled 96.5 Wh) is the volume-selling long-haul model. Port layout is 3 USB-A output, dual micro-USB input, 15W maximum output per port. It is the sharpest pick for travellers whose charging needs are phone, earbuds, and tablet rather than laptop, because the USB-A layout matches most airline seatback USB ports and the mAh capacity covers 5 to 7 full iPhone charges or 2 to 3 iPad charges per fully-charged bank.

Anker Prime 20000

The Anker Prime 20000 (20,000 mAh, 72 Wh, 200W total output) is the higher-power option with USB-C PD in and out. It charges a 13-inch MacBook Air from 0 to 50 percent in roughly 45 minutes at 100W PD delivery, and the total 200W spread across two USB-C and one USB-A ports lets a family of three top up phones and a laptop simultaneously. Weight is 429 g, roughly 100 g lighter than the PowerCore 26800.

Anker 737 Power Bank

The Anker 737 Power Bank (24,000 mAh, 87.6 Wh, 140W USB-C PD output) sits between the two and delivers enough PD headroom for a 14-inch MacBook Pro or a Dell XPS 15 at close to wall-adapter speed. The 140W output rating exceeds any airline seatback USB provision, which makes it the strongest pick for travellers who plan to work on a laptop in-flight and cannot rely on in-seat AC power.

Which Anker models cross the 100Wh threshold?

Anker's PowerHouse portable-station line (PowerHouse 200, PowerHouse 400, PowerHouse 767) all exceed 160Wh and are not cabin-permitted. The Anker 100W PowerCore Compact 30,000 mAh model is over 100 Wh at 3.6 V nominal and requires airline approval for cabin carry.

What Mophie Powerstation Pro models pass the airline-safe test?

Mophie's Powerstation Pro range publishes Wh ratings on the label, which is the key check before travel.

Mophie Powerstation Pro XL

The Mophie Powerstation Pro XL (25,000 mAh at 3.7 V nominal, 92.5 Wh, 20W USB-C PD output) is the flagship carry-on model in the range. It sits under the 100Wh limit with 7.5 Wh of headroom, includes Qi wireless charging on some SKUs, and comes with a soft-touch fabric shell that is more travel-friendly than a bare aluminium finish.

Mophie Powerstation Plus 10000 and 20000

The Powerstation Plus 10,000 mAh model (37 Wh) and 20,000 mAh model (74 Wh) both sit comfortably under 100Wh. The 20,000 mAh model is a common recommendation for phone-plus-tablet travellers on shorter regional Australian routes (Sydney to Perth, Brisbane to Cairns) where a full 26,800 mAh bank is more capacity than needed.

Which Mophie products should not travel by air?

Mophie's Powerstation Go jump-starter product line (typically 44,400 mAh at 3.7 V, 164 Wh) exceeds the 160Wh airline cabin ceiling and is not permitted on passenger aircraft. Any Mophie SKU labelled above 100 Wh needs airline approval before cabin travel.

In-body merchant callouts

Anker on eBay Australia and JB Hi-Fi via ShopBack

Anker's Australian retail distribution runs through eBay Australia (official Anker store), JB Hi-Fi, Officeworks, Amazon Australia, and Kogan. Australian shoppers can open the ShopBack app or activate the ShopBack browser extension on desktop before checkout on eBay Australia, JB Hi-Fi, or Officeworks to earn cashback into a ShopBack balance on Anker power bank purchases. The 26800 model retails 79 to 99 AUD, the Anker Prime 20000 sits at 129 to 149 AUD, and the Anker 737 typically at 199 to 249 AUD depending on the current sale window. Cashback on eBay Australia has historically been the highest rate for third-party Anker sellers, though the official Anker store on eBay is usually the safer purchase for warranty support.

Mophie on Apple Store, JB Hi-Fi, and Officeworks

Mophie's Australian distribution runs through the Apple Store, JB Hi-Fi, Officeworks, and Harvey Norman. The Powerstation Pro XL retails 149 to 179 AUD, and the Powerstation Plus 20,000 mAh at 79 to 99 AUD. Australian shoppers can activate the ShopBack browser extension on JB Hi-Fi or Officeworks before checkout to earn cashback on the purchase. Apple Store direct is often not a ShopBack partner; buying Mophie at Apple Store is the right call for AppleCare integration but leaves cashback on the table versus buying the same SKU at JB Hi-Fi with the ShopBack extension active.

Zendure on Amazon Australia and Kogan

Zendure sells into Australia primarily through Amazon Australia and Kogan, with limited presence at JB Hi-Fi and Officeworks. The Zendure SuperTank retails 179 to 249 AUD depending on the current sale window, and the SuperPack at 149 to 199 AUD. Australian shoppers can activate the ShopBack browser extension before checkout on Kogan to earn cashback on the purchase. Amazon Australia sits behind a different affiliate structure; check the current ShopBack cashback rate on the Amazon Australia merchant page before deciding between retailers, and note that Kogan often runs shipping-included promotions that make it cost-competitive with Amazon even before cashback.

ShopBack app for stacking cashback with retailer sales

The ShopBack app for iOS and Android and the ShopBack browser extension on Chrome, Edge, and Safari deliver cashback across 1,500-plus Australian retailers, including all the major electronics chains that stock power banks. For a traveller planning a 200 to 300 AUD power bank purchase, activating cashback before checkout at JB Hi-Fi or Kogan typically returns 4 to 15 AUD to a ShopBack balance, and combining that with a sale price during EOFY (June to July), Click Frenzy (November), or Boxing Day (December) can bring the effective net price down meaningfully. Cashback withdraws to any Australian bank account at a low minimum threshold.

Which Zendure SuperTank and SuperPack models pass?

Zendure's SuperTank and SuperPack lines both publish Wh ratings on-device.

Zendure SuperTank

The Zendure SuperTank (26,800 mAh at 3.7 V, 96.5 Wh, 100W USB-C PD input and output on all four USB-C ports) is the sharpest laptop-charging power bank in the sub-100 Wh cabin-legal band. The 100W PD out on the primary port charges a 13-inch or 14-inch MacBook at wall-adapter parity, and the 100W PD in re-fills the bank in roughly 90 minutes from an AC-USB-C wall adapter or airline in-seat AC. Weight is 585 g.

Zendure SuperPack

The Zendure SuperPack (27,000 mAh at 3.6 V nominal, 97.2 Wh, 65W USB-C PD out) is the mid-tier alternative at a lower price point. It charges a MacBook Air at wall-adapter speed and a 14-inch MacBook Pro at slightly reduced speed. The port layout is 2 USB-C plus 1 USB-A, which is a leaner spread than the SuperTank's 4 USB-C.

Which Zendure products are not cabin-legal?

Zendure's SuperBase Pro portable station range (1,500 Wh and above) is not cabin-permitted and is designed for camping and home-backup use rather than air travel.

How do the three brands compare on port layout and PD output?

Port layout matters more than raw mAh for a laptop-carrying traveller, because a bank with only USB-A cannot deliver PD charging to a USB-C laptop.

Anker port layout

Anker PowerCore 26800 has 3 USB-A output. Anker Prime 20000 has 2 USB-C plus 1 USB-A. Anker 737 has 2 USB-C plus 1 USB-A. USB-C PD ratings run 20W (PowerCore) to 140W (737).

Mophie port layout

Mophie Powerstation Pro XL has 1 USB-C PD plus 2 USB-A, PD output rated 20W. Mophie Powerstation Plus 20,000 mAh has 1 USB-C PD plus 1 USB-A, PD output rated 18W to 20W.

Zendure port layout

Zendure SuperTank has 4 USB-C ports (1 x 100W PD, 2 x 60W PD, 1 x 18W PD) with no USB-A. Zendure SuperPack has 2 USB-C plus 1 USB-A. This is the port-density and PD-power-delivery leader in the sub-100 Wh cabin-legal band.

When does an Australian actually need a 100W PD power bank?

Not always. The 100W PD tier matters if the traveller intends to work on a MacBook Pro, ThinkPad, or XPS laptop for extended stretches on a flight that has no in-seat AC power. For phone, earbuds, tablet, and Kindle charging, 20W PD or standard USB-A is enough and the extra 60 to 80 AUD price premium of a 100W PD bank is not justified.

Which Australian domestic and regional routes lack in-seat AC power?

Most Qantas and Virgin Australia narrow-body domestic routes (Boeing 737, Airbus A320, Airbus A220) do not offer in-seat AC power. Wide-body domestic routes (Qantas A330, Boeing 787 on Sydney to Perth) and all international long-haul routes do. Jetstar economy typically does not offer in-seat AC. If the primary use case is a working laptop on a Sydney to Perth or a Sydney to Auckland leg, a 100W PD bank meaningfully changes the productive time available.

Which flights have USB-C ports at the seat?

Newer widebody aircraft (Qantas A350 order due 2026 onwards, Boeing 787 refurbished cabins from 2024, A330neo) increasingly ship with in-seat USB-C ports rated 60W PD. Older cabin refits offer USB-A only at 5W to 10W, which cannot fast-charge a modern smartphone let alone a laptop. A 100W PD power bank is a hedge against older-cabin allocation.

Should you carry more than one power bank on a flight?

Reasonable-personal-use covers 2 to 3 sub-100 Wh banks per passenger without gate-agent friction. Beyond that, expect a personal-use question at security or the gate. For a family of four flying together, 4 to 5 power banks across the party is normal and rarely questioned.

How does a family of four typically pack for a long-haul?

A common family-of-four long-haul pack is: 2 x 26,800 mAh USB-A-heavy banks (Anker PowerCore 26800) for phones and tablets, 1 x 20,000 mAh USB-C PD bank (Anker Prime 20000 or Zendure SuperPack) for the working laptop, and a small 10,000 mAh bank (Mophie Powerstation Plus 10,000) as the day-out bag battery. Total Wh: 96.5 + 96.5 + 72 + 37 = 302 Wh across four sub-100 Wh units, all cabin-legal individually.

What about lithium-polymer versus lithium-ion labelling?

Both lithium-polymer and lithium-ion power banks fall under the same IATA 100Wh cabin limit. The chemistry difference is irrelevant to the airline rule. What matters is the Wh printed on the label and the placement in the cabin (not checked luggage).

FAQs

What is the 100Wh airline power bank limit and how is it calculated?

The 100Wh limit is the IATA lithium-battery threshold above which a power bank is either restricted or prohibited in aircraft cabins. Watt-hours equal ampere-hours multiplied by voltage (Wh = Ah x V). A 20,000 mAh power bank at 3.7 V lithium-ion nominal voltage equals 74 Wh, which is under the limit. A 27,000 mAh bank at 3.7 V equals 99.9 Wh, still under the limit. Anything above 100 Wh needs airline approval, and anything above 160 Wh is not permitted in passenger aircraft at all under IATA and ICAO rules.

How did Qantas change its power bank rules in 2025?

Qantas updated its dangerous-goods guidance from mid-2025 to require passengers to physically carry power banks in the passenger cabin rather than stowing them in overhead-bin luggage that could be removed to the cargo hold at the gate. The 100Wh cabin limit remained unchanged. The change followed a series of lithium-battery incidents in international aviation through 2024 and 2025. Virgin Australia and Jetstar carry similar guidance; verify each airline's current dangerous-goods page as of 2026-08-26.

Which Anker power banks are airline-safe for Australian travellers?

Most Anker PowerCore models under 27,650 mAh sit below 100 Wh and are cabin-permitted on Qantas, Virgin Australia, and Jetstar. The Anker PowerCore 26800 (26,800 mAh, 96.5 Wh), the Anker PowerCore III Elite 25600 (25,600 mAh, 94.7 Wh), and the Anker Prime 20000 (20,000 mAh, 72 Wh) all clear the limit comfortably. The Anker 737 Power Bank (24,000 mAh, 87.6 Wh) also clears. Anker's higher-capacity portable-station products (PowerHouse 200 and above) exceed 160 Wh and are not permitted in passenger aircraft cabins.

Are Mophie Powerstation Pro power banks cabin-legal?

Yes for the mainstream range. The Mophie Powerstation Pro XL (25,000 mAh, 92.5 Wh) and Powerstation Plus (10,000 to 20,000 mAh, 37 to 74 Wh) all sit under the 100 Wh cabin limit. Mophie's Powerstation Go product line (jump-starter category, typically 44,400 mAh at 3.7 V nominal, 164 Wh) is not cabin-permitted. Check the Wh rating printed on the label of the specific unit before packing, as some Mophie SKUs are voltage-labeled at 3.85 V rather than 3.7 V.

Do Zendure SuperTank and SuperPack models pass the 100Wh limit?

The Zendure SuperTank (26,800 mAh, 96.5 Wh) sits just under the 100 Wh cabin limit and is airline-permitted. The Zendure SuperPack (27,000 mAh, 96.4 Wh) is also under the limit. The Zendure SuperBase Pro (large portable station, 1,500 Wh or more) is not cabin-permitted. Zendure discloses the Wh rating on-device and on packaging, which makes gate-agent verification straightforward relative to some competitor products that only print mAh.

When does gate-agent enforcement kick in on multiple power banks per passenger?

IATA guidance permits up to 2 spare lithium batteries or power banks between 100 Wh and 160 Wh with airline approval, and typically unlimited quantity of power banks under 100 Wh in the cabin, subject to reasonable-personal-use limits and each airline's specific policy. Qantas, Virgin Australia, and Jetstar all follow IATA on the 100 Wh threshold. In practice, gate agents rarely question 2 to 3 sub-100 Wh banks per passenger; carrying 5 or more may draw a personal-use question.

Would a 20,000 to 26,800 mAh bank cover a 14-hour Sydney to London flight?

For a 14-hour ultra-long-haul flight where seatback USB may not deliver full charging speed, a 20,000 to 26,800 mAh power bank in the 72 to 96.5 Wh range is the sensible pick. The Anker PowerCore 26800, Zendure SuperTank, and Mophie Powerstation Pro XL all fall in this band. Choose based on port layout: Anker PowerCore 26800 has 3 USB-A outputs, Zendure SuperTank has 4 USB-C outputs with 100W PD input and output, and Mophie Powerstation Pro XL offers USB-C PD and Qi wireless charging on some SKUs.

Can Australians save on power bank purchases through ShopBack?

Yes. Australian shoppers can open the ShopBack app or activate the ShopBack browser extension before checkout on eBay Australia, Amazon Australia (via linked cashback partners), Kogan, Catch, JB Hi-Fi, and Officeworks to earn cashback into a ShopBack balance on Anker, Mophie, and Zendure power bank purchases. Cashback stacks with retailer sale prices, and typical checkout runs 2 to 6 percent back on eligible electronics categories. Check the merchant page on ShopBack for the current rate before checking out.

Will a PD 100W power bank charge a laptop mid-flight?

Yes, with caveats. The Zendure SuperTank (100W USB-C PD in and out) and the Anker 737 Power Bank (140W USB-C PD out) can charge most 13-inch to 15-inch Windows laptops and every MacBook Air and 14-inch MacBook Pro at close to wall-adapter speed. 16-inch MacBook Pro and larger 16-inch Windows workstations often exceed the 100W to 140W supply during heavy CPU load, so charging happens but is slower than a wall adapter. Airline in-seat AC power is more reliable for full charging on any 15-inch or larger laptop.

Should you fly with a lithium power bank in checked luggage in Australia?

No. IATA rules prohibit lithium-ion power banks and spare batteries in checked luggage on passenger aircraft. This applies to every Australian domestic and international flight on Qantas, Virgin Australia, Jetstar, and every partner carrier. Power banks must travel in the passenger cabin with the traveller, in a bag that stays under the seat or in the overhead bin. Gate-checked bags moved to the cargo hold at boarding must have any power bank removed and hand-carried.
