The short answer

Yes, in your hand luggage. Never in the hold.

You can take a power bank on a plane with every airline in our table, as long as it stays in the cabin and under 100Wh (roughly 27,000mAh). Checked luggage is the rule that catches people out: a power bank in a hold bag can get your luggage pulled at any airport in the world.

  • Up to 100Wh: allowed in the cabin on all 25 airlines below
  • How many: two on most airlines, but only one on Emirates, Wizz Air and Southwest
  • Using one in flight: banned on most carriers since the 2026 rule changes, though a few still allow it

Can you take a power bank on a plane: flight-safe power banks packed for hand luggage

The 4 numbers that matter

Everything below unpacks these. If you only remember 4 things, make it these 4.

100WhThe universal ceiling. Under this, every airline here says yes.
0In the hold. No airline, anywhere, allows a power bank in checked luggage.
1Banks allowed on the strictest carriers (Emirates, Wizz Air, Southwest). Most allow two.
160WhThe absolute max. Above this it doesn’t fly, and many airlines now stop at 100.

Can you take a power bank on a plane? The core rules

Three rules cover 90% of trips. The exceptions are where it gets interesting.

Short answer: keep every power bank in your hand luggage, keep each one under 100Wh, and assume you can’t use it during the flight unless your airline says otherwise. Those three rules clear you on every airline in this guide.

The hand-luggage rule isn’t airline fussiness. A lithium battery fault produces smoke and heat fast, and in the cabin the crew can reach it in seconds. In the hold, nobody can. That’s why the CAA and IATA put spare batteries in the cabin, and every airline follows.

The 100Wh figure is printed on most power banks, and where it isn’t, you can work it out: multiply the mAh by 3.7 and divide by 1,000. A 20,000mAh bank is 74Wh, comfortably inside the limit.

What changed in 2026 is everything else. After a run of in-flight incidents, regulators tightened the framework in March, and each airline has interpreted it its own way.

Ten airlines now refuse any power bank over 100Wh outright. Six of those go further and treat power banks as their own category, stricter than their rule for spare batteries: British Airways, American, Southwest, Thai, Wizz Air and Emirates.

Three of them allow only one per passenger. That divergence is why the table below exists.

Hong Kong security confiscates and does not return. Cathay Pacific’s restriction is Hong Kong law, not airline preference: a non-compliant power bank taken at HKG security is gone for good, not held for collection.
Good news: if your power bank is under 100Wh and stays in your hand luggage, you’ll clear every airline in this guide without a second look.
Darleene Darleene asks
“Mine doesn’t say watt-hours anywhere. It just says 20,000mAh. How am I supposed to know if it’s allowed?”

Alan: multiply the mAh by 3.7 and divide by 1,000. So 20,000mAh is 74Wh, comfortably under the limit.

If maths on the way to the airport isn’t your thing, the rule of thumb is that anything sold as 27,000mAh or less is fine.

One catch since 2026: a few airlines refuse banks with no rating printed on the casing at all, so if yours has worn blank, replace it before you fly.

Rule of thumb
Plan for the strictest airline on your ticket, not the one you check in with.

What does every airline allow?

Power bank airline rules for 25 carriers. Every airline name links to that carrier’s own policy page, so you can check any row for yourself.

Short answer: under 100Wh in the cabin is universal: you can take a power bank on a plane with every carrier below. The differences are in how many banks you can bring, whether you can use one in flight, and what happens above 100Wh, and the airlines now openly disagree on all three.

What the airlines disagree on

We checked all 25 against their own published policies in July 2026. There is no single rule.

10of 25

refuse any power bank over 100Wh, with no approval route at all

British Airways, Ryanair, Wizz Air, Iberia, American, Southwest, JetBlue, Emirates, Qatar and Thai. The other 14 allow up to 160Wh with prior approval.

16of 25

ban using a power bank at any point during the flight

Only seven permit it with conditions. Qatar is the only long-haul carrier here that still allows in-flight use.

5of 25

will refuse a power bank with no capacity printed on it

British Airways, Jet2, KLM, Wizz Air and Emirates. If the figure has rubbed off, those five can refuse it at the gate whatever its real size.

1of 25

publishes no power bank policy at all

TUI Airways. With nothing published, the CAA baseline applies: cabin only, 100Wh without approval. Ask them directly before you fly.

Figures as at July 2026, from each airline’s own published policy. Every source is linked in the table below.

Where your power bank sits

Airlines measure watt-hours, not milliamp-hours. The number on the box is almost never the number they check.

Under 100Wh
Allowed on all 25No approval needed anywhere. Quantity limits still apply.
100 to 160Wh
14 allow it, 10 refuse itWhere it is allowed you need approval before you travel, usually a form or a phone call. Turning up with one is not enough.
Over 160Wh
Refused everywhereNo airline in this table permits a power bank above 160Wh in the cabin, and none may go in the hold.

What that means in mAh

10,000mAh37Wh, fine everywhere
20,000mAh74Wh, fine everywhere
25,000mAh92.5Wh, fine everywhere
27,000mAh100Wh, the cliff edge
30,000mAh111Wh, approval or refused
40,000mAh148Wh, approval or refused

Why some rows below say more than two. Those figures are what each airline publishes, and we have left them as published.

The regulation sets a lower floor. The UK CAA lists power banks as their own category, capped at no more than two per person whatever their size. Spare batteries under 100Wh carry no equivalent quantity cap, and several carriers still describe power banks under that older spare-battery wording.

So a carrier page offering five, twenty, or no figure at all is describing an allowance the regulation no longer supports for power banks. Carry two and you are inside both.

We recheck every row quarterly. Airlines can change rules without notice, which is why every airline name links to the carrier’s own page, so you can verify for yourself.

How we checked this

Every row in the table above was read on the airline’s own website, not taken from another guide or a news report. The airline name in each row links to the exact page we read.

  • What counts as a source. Only the carrier’s own published policy. Where an airline publishes nothing, we say so rather than applying a guess.
  • Ambiguous wording. Where a policy bans recharging the bank but is silent on using it, we record that as use permitted and recharging banned, because that is what the airline has written. British Airways is the clearest example.
  • Group carriers. Where a group publishes one standard, we cite the member airline whose page states it. The Lufthansa Group row is verified on the SWISS page.
  • Dates. Every row carries the month we last read it. Where an airline has dated its own change, we record that date too.
  • Corrections. If we have a row wrong, tell us and we will fix it and note the change in the log below.

What do I do if security questions my power bank?

Work through these in order. Most cases end at step 1.

1

Show the Wh marking

Point to the watt-hour figure printed on the casing. If it reads 100Wh or less, that usually ends the conversation.

2

Do the mAh conversion for them

If only mAh is printed: mAh times 3.7, divided by 1,000. Say the result out loud; officers hear it daily.

3

Ask for a supervisor before surrendering it

If the marking is worn or missing, a supervisor can accept the manufacturer’s spec page on your phone. A surrendered bank at some airports isn’t coming back.

Darleene
Darleene’s takeI keep my big power bank in the same pocket of my hand luggage every trip, so I’m never digging for it at the security tray.

Is there such a thing as a TSA-approved power bank?

Search the phrase and you’ll find it on hundreds of product listings. No such certification exists.

Short answer: No. The TSA does not approve, certify or test individual power banks, and it publishes no list of approved models. A power bank sold as TSA approved is carrying a marketing phrase, not a certification.

The TSA screens bags at US airport checkpoints. Its own guidance on power banks runs to two lines, carry-on yes and checked bags no, and it sets out no certification a power bank could hold.

The rules themselves come from elsewhere. In the US it’s the FAA, internationally it’s ICAO, and the UK CAA follows the ICAO framework. Your airline then layers its own policy on top, and that layer is usually the strictest one on your ticket.

So there’s no label to shop for. Four things decide whether your bank flies:

  • Watt-hours. Under 100Wh clears every airline in the table above, no approval needed. Convert your bank’s mAh to watt-hours if the rating isn’t printed.
  • Hand luggage. Never the hold, on any airline, at any capacity.
  • How many. Two per person is the current international ceiling, and several airlines allow only one.
  • A legible printed rating. Security staff can refuse an unmarked bank even when it’s well under the limit.

One more reason no badge can promise you anything: the TSA states that the final decision rests with the officer at the checkpoint. A compliant bank is still a judgement call on the day.

A TSA approved badge buys you nothing at the gate. It normally means the bank is under 100Wh, and that is the number that matters most. It tells you nothing about your airline’s quantity limit or whether you can use the bank in flight, which are the rules that catch people out.

Pack it right, first time

The hand luggage habits that keep you out of the secondary-search queue.

Do

  • Keep every power bank in your hand luggage, under the seat where the airline asks for it
  • Check the strictest airline on your whole itinerary, not only the first leg
  • Keep the printed rating legible, and tape over the terminals of loose spare batteries

Don’t

  • Put a power bank in a checked bag, ever
  • Charge your phone from it mid-flight unless your airline’s row says you can
  • Fly with a swollen, dented or unmarked bank; replace it before the trip

What changed, and when

The rules have moved five times in eighteen months. The dates matter if your last flight was a while ago.

Mar 2025Thai Airways bans in-flight use (from 15 Mar 2025), one of the first carriers to split power banks out from ordinary batteries.
Oct 2025Emirates cuts the allowance to one bank per passenger, 100Wh, seat pocket or under the seat only (announced Aug 2025, in force 1 Oct).
Mar 2026ICAO and the CAA tighten the framework (27 Mar). Airlines start rewriting their own policies, each in its own way.
Apr 2026The divergence wave. Singapore Airlines (15 Apr), Southwest (20 Apr) and Japan Airlines (24 Apr) all publish new rules within ten days of each other, and they don’t match.
Jun 2026Finnair’s new limits take effect (24 Jun).
Jan 2027Japan Airlines may cut its 160Wh allowance to 100Wh. Flagged on JAL’s own notice; we’ll update this page when confirmed.

Is your power bank under the limit?

Check the maths in ten seconds, or use the full calculator.

Wh = (mAh ÷ 1,000) × 3.7. Nearly all power banks use lithium-ion cells at a nominal 3.7V, the figure airlines themselves use.

Three flight-safe picks

All three clear every airline in the table above, with the watt-hour rating printed on the casing.

Anker 737 power bank at an airport gate Best overall

Anker 737 (89Wh)

The biggest bank that still flies everywhere: 24,000mAh, laptop-capable output, and the 89Wh rating printed right on the casing.

Anker 87W A1383 power bank Best value

Anker 87W A1383 (74Wh)

20,000mAh with fast charging for a phone and laptop both, and enough headroom under the limit that no security officer looks twice.

Anker A1695 power bank with built-in cables at the airport Travel pick

Anker A1695 (90Wh)

Built-in cables mean two fewer things to dig out of your bag at the tray, and 90Wh still clears the universal ceiling.

Power banks on planes: your questions, answered

The questions readers ask most, with the direct answer first.

What does TSA approved mean on a power bank listing?
Nothing official. The TSA does not certify power banks, so the phrase is seller marketing. It normally signals the bank is under 100Wh, which is the capacity every airline accepts in hand luggage.
Can I take a 20,000mAh power bank on a plane?
Yes. 20,000mAh is 74Wh, well under the 100Wh limit every airline applies. Keep it in your hand luggage.
What happens if I leave a power bank in my checked bag?
Your bag is likely to be pulled and searched, and the power bank removed. On some routes the bag misses the flight while that happens.
Can I use a power bank during the flight?
On most airlines, no longer. Since the 2026 rule changes most ban it outright. The exceptions in our table: Ryanair and United allow it with conditions, Delta allows it at cruise, American asks you to keep it visible, and Qatar permits supervised use. Check your airline’s row.
How many power banks can I take on a plane?
Two on most airlines. Emirates, Wizz Air and Southwest now allow only one. Ryanair counts them inside its overall 20-spare-battery allowance.
My power bank has no Wh rating printed on it. Will it fly?
Maybe not. British Airways, KLM, Wizz Air and Jet2 all say unmarked banks can be refused. You can work out the Wh from the mAh, but the printed rating is what the officer goes by, so replace a worn-blank bank before you travel.
What about connecting flights on different airlines?
The strictest airline on your ticket sets your rule, because your bank has to clear every leg. Fly British Airways into Hong Kong and connect onto Cathay Pacific, and Hong Kong law applies at the transfer even though BA carried it happily on leg one.
Is a 30,000mAh power bank allowed on a plane?
That’s about 111Wh, so it’s in approval territory at best. easyJet and Jet2 approve up to 160Wh automatically; BA, Ryanair, Wizz Air, Emirates and others refuse anything over 100Wh outright. Check your row before you buy the ticket, not after.
Can I put my power bank in the overhead locker?
Increasingly no. Most carriers in our table now require the seat pocket, under the seat in front, or on your person. Qantas is the only airline here that permits the locker at all, and only as a fallback.
Why did the rules change in 2026?
A run of in-flight battery incidents pushed ICAO and national regulators, including the CAA, to tighten the framework on 27 March 2026. Airlines then rewrote their own policies individually, which is why they now disagree with each other.
Are the UK and US rules different?
The CAA and FAA baselines match: 100Wh in the cabin without approval, up to 160Wh with, nothing in the hold. What bites is the airline layer on top, which is where the one-bank limits and usage bans live.
If security takes my power bank, do I get it back?
Usually not. Surrendered items at UK airports are rarely retrievable, and at Hong Kong security confiscated banks are not returned or stored at all.
What size power bank is best for flying?
The sweet spot is 20,000 to 27,000mAh: big enough for a long-haul trip, still under the 100Wh ceiling every airline accepts. Our best power banks roundup only includes flight-safe picks.
