The 100 Wh cabin limit is set by regulation, not by the manufacturer

The best travel power banks for 2026

Most airlines follow an international safety rule permitting power banks up to 100 watt-hours in carry-on baggage without special approval, and larger capacities between 100 and 160 Wh commonly need prior airline approval — power banks above that are typically barred from flights entirely, checked baggage included. We compare stated watt-hour rating (not just the milliamp-hour figure most listings lead with, which requires a conversion to compare against the actual limit), charging speed, and the number of devices it can charge at once.

What we recommend

1. 

   Best all-rounder

   Anker Nano 10000mAh Power Bank

   A 10,000 mAh power bank with an integrated cable and a watt-hour rating comfortably under the international 100 Wh cabin limit.

   • Integrated USB-C cable means one less cable to pack or lose
   • 30W output charges a phone quickly, and some smaller laptops
   • 10,000 mAh gives one to two full phone charges, not multiple days of heavy use

   8.3/10 ≈ $50

2. 

   UGREEN Zapix 10000mAh MagSafe Power Bank

   A magnetic wireless power bank compatible with MagSafe phones, alongside wired USB-C charging for other devices.

   • Magnetic attachment charges a compatible phone with no cable at all
   • USB-C port covers devices that are not MagSafe-compatible
   • Magnetic charging only works with MagSafe-compatible phones or a magnetic case

   ≈ $40

3. 

   VEGER V1202, 10000 mAh 22.5 W

   The cheapest bank on this shelf, and one of only two that tells you how much power is left when you charge four things at once.

   Amazon reference

   B0FCM85RXN

   EAN

   6977525751493

   • Publishes the shared total: four devices at once, 15 W between them — against a 22.5 W headline for a single device
   • Publishes the weight and all three dimensions: 180 g (6.3 oz), 6.35 oz, 4.57 by 2.83 by 0.66 in
   • Publishes no watt-hour figure, like every listing in the American half of this hub — by the formula in this shelf's buying tip, 10,000 mAh is roughly 37 Wh

   Best for: A group charge where the honest figure is the shared one, not the headline

   ≈ $20

4. 

   charmast W1148, 10000 mAh with built-in cables

   The only bank on this shelf with no charging-speed figure of any kind — on a listing that gives its own cable count three different ways.

   Amazon reference

   B0H2YM86Z9

   EAN

   6973369746459

   • Built-in cables for USB-C, iPhone and Micro-USB, so three connector types travel with the bank
   • Three extra ports — one USB-C and two USB-A — for a stated six devices at once
   • Publishes no wattage at all — not for a single device and not for six, where every other bank on this shelf gives at least one figure

   Best for: A family or a group, where never losing a cable matters more than charging fast

   ≈ $21

5. 

   INIU BI-B41, 10000 mAh 45 W TinyCell

   The only bank on this shelf whose charging claims state what charge they start from — and the one that argues hardest for a cable you can replace.

   Amazon reference

   B0DFLNL3XM

   EAN

   6975141098664

   • States the starting charge behind its percentage claims — iPhone 17 Pro Max to 76 per cent, Galaxy S25 Ultra to 84, iPad Pro to 60, in 30 minutes from 20 per cent
   • 45 W, which covers tablets and some small laptops rather than phones alone
   • Publishes no dimension and no weight at all, while claiming to be 40 per cent smaller and 36 per cent lighter than "conventional chargers" it never identifies

   Best for: Keeping a bank for years, where the cable is the part that will fail first

   ≈ $22

6. 

   INIU P61-E1, 10000 mAh 45 W with stand

   The INIU that publishes its dimensions and its weight, translates its capacity into four kinds of device — and names a different model number in its own second bullet.

   Amazon reference

   B0DC9PV394

   EAN

   6975141097889

   • Publishes all three dimensions and the weight: 4.4 by 2.7 by 0.7 in and 6.5 oz
   • A built-in phone stand, so the bank props the screen for a film or a map instead of lying under it
   • The second bullet calls the product "P55" while the reference is P61-E1 and the title names neither

   Best for: A tray table, where a bank that props the phone up earns its place twice

   ≈ $27

7. 

   LUCKYFELLOW PB180W, 10000 mAh magnetic with AC plug

   Six devices at once from a bank that plugs straight into a wall — on a listing whose very first bullet is a workaround for its own magnetic charging.

   Amazon reference

   B0H4KZV8BK

   EAN

   0732133996522

   • A built-in AC wall plug, so the bank recharges from a socket with nothing else packed
   • Publishes both recharge times, and they are the interesting comparison: 3 to 4 hours from the wall plug against 2.5 to 3 hours over 20 W USB-C
   • The first of six bullets is a troubleshooting instruction: remove the watch band before charging an Apple Watch on it

   Best for: Traveling without a charger at all, where the bank is also the plug

   ≈ $40

8. 

   Tlsic PS-BOO3WA Powerpack Universal, 5-in-1

   A power bank, a wireless pad and a travel plug adapter set in one object — at nearly the price of the 20,000 mAh bank on this shelf.

   Amazon reference

   B0CW9C8GZN

   EAN

   0746626709063

   • Includes three interchangeable travel plugs — EU, AU and UK — which are the three standards an American traveler runs into most
   • A Qi wireless pad with non-slip rubber padding, so a compatible phone charges without a cable
   • 10,000 mAh at within a dollar of the 20,000 mAh, 87 W bank on this shelf — half the capacity and a fraction of the output for the same money

   Best for: One object instead of three, on a trip through Europe, the UK or Australia

   ≈ $69

9. 

   Anker A1383011, 20000 mAh 87 W

   The only bank on this shelf above 10,000 mAh, the only one that charges a laptop properly, and the only one to publish both a shared total and a single-device maximum.

   Amazon reference

   B0CXDXP8VR

   EAN

   0194644043711

   • Publishes both figures that matter for multi-device charging: 87 W shared across three devices, up to 65 W to a single one
   • Twice the capacity of everything else on this shelf — 20,000 mAh, roughly 74 Wh by the buying tip's formula, still inside the 100 Wh limit
   • Says it is "also approved for airline travel" without publishing a watt-hour rating, and at roughly 74 Wh it is the closest bank on this shelf to the 100 Wh limit

   Best for: A laptop and two phones on a long-haul day, where 10,000 mAh is not enough

   ≈ $70
