Ryanair Power Bank Rules 2026: Two Banks, 100Wh, Under the Seat

Can you bring a power bank on Ryanair? Two, under 100Wh, in the small bag

Ryanair’s rule is built around its bag policy. The free cabin allowance is one 40 x 30 x 20 cm bag under the seat, and that is exactly where Ryanair wants the power bank. If you paid for a wheeled 10 kg bag, the bank does not travel in it, because that bag goes in the overhead locker or, on a full flight, in the hold.

How this page was built. VoyageHacks read Ryanair’s “What items are permitted on board” help page on 16 September 2026 and quotes it directly below, alongside the UK Civil Aviation Authority’s power bank guidance and IATA’s 31 March 2026 operator guidance. All 38 carriers are compared in power bank rules by airline.

Ryanair’s power bank rules in one table

What Ryanair’s page says, word for word

Read on 16 September 2026:

• “You may carry up to 20 spare lithium batteries in total, each not exceeding 100Wh.”
• “Power banks are limited to a maximum of 2 per passenger and are included within the overall limit of 20 spare batteries (e.g. 2 power banks + 18 spare lithium batteries).”
• “Spare lithium batteries and power banks must be carried on the passenger’s person or in the underseat cabin bag stowed under the seat in front. Spare lithium batteries and power banks cannot be placed in cabin baggage stored in the overhead lockers.”
• “Devices or batteries exceeding 100Wh are not permitted in either cabin or checked baggage.”
• “Power banks must not be recharged at any time while onboard or during the flight (e.g., one power bank charging another).”
• “Power banks may be used to charge personal electronic devices, except during taxi, take-off, and landing, or when instructed otherwise by the crew.”

Is your power bank under 100Wh?

Ryanair’s limit is a hard 100Wh with nothing above it. Read the Wh printed on the case or convert with Wh = mAh x 3.7 / 1,000.

A bank with the label worn off is the one that gets questioned at the gate, so if only mAh is printed, write the Wh on a piece of tape.

The under-seat bag rule, and what it means for Priority passengers

Ryanair’s stowage rule is the one that catches Priority and 10 kg bag customers. The wheeled bag goes in the overhead locker, and the page says power banks “cannot be placed in cabin baggage stored in the overhead lockers”. So the bank moves from the wheeled bag to the small under-seat bag, or to a jacket pocket, before boarding.

On a full flight the wheeled bag may be tagged at the gate and put in the hold. The bank cannot go with it, and unpacking at the gate is the usual result of leaving it there. Sort it at home.

Ryanair’s under-seat bag limit of 40 x 30 x 20 cm is also the size everything else has to fit in, which is why the grid above leads with a 215 g bank. Our guide to personal-item bags that fit Ryanair’s sizer covers the bag itself.

Using a power bank on a Ryanair flight

Ryanair is one of the few European airlines that still lets you use the bank in the air, and the reason is practical: Ryanair’s Boeing 737s have no USB ports or AC outlets at the seat, so the bank is the only way to charge a phone on a three-hour flight.

The conditions are that you do not use it during taxi, take-off or landing, that you stop if the crew say so, and that the bank itself is never recharged on board. Keep it out of the bag while it works, on your lap or in the seat pocket, so the crew can see it. Compare easyJet, which bans using a power bank on board entirely, and Lufthansa, which has banned it since 15 January 2026.

Recalled power banks

Ryanair’s page does not list recalled models, but the UK CAA and EASA rules bar damaged or recalled lithium batteries from passenger aircraft. Check the model number on the case against these CPSC recalls before you pack:

The A1689 is the Anker Zolo 20,000mAh 30W USB-C model, banned by name on Air Canada’s page. The three banks in the grid above are A1259, A1383 and A1340, none of which is recalled as of 16 September 2026.

How Ryanair compares with easyJet, Wizz Air and Vueling

If you fly Ryanair out and Wizz Air back, pack for Wizz Air: one bank, and no using it at all.

What changes on 1 January 2027

Nothing on Ryanair. IATA’s operator guidance of 31 March 2026 says the 100 to 160Wh approval tier for power banks “will not be carried into the 68th edition” of the Dangerous Goods Regulations, in force from 1 January 2027, making 100Wh the ceiling everywhere. Ryanair already applies a flat 100Wh with no tier above it.

Before you fly Ryanair: the 60-second check

1. Two banks, 100Wh each. A 30,000mAh unit stays home.
2. Read the Wh on the case, or mAh x 3.7 / 1,000.
3. Check the model against the recall table above.
4. Bank in the small under-seat bag or your pocket, not in the wheeled bag.
5. Use it in cruise only, in the open, and never plug the bank into anything.
6. Full flight? The wheeled bag may go in the hold at the gate; the bank does not.

Frequently asked questions

How many power banks can I bring on Ryanair?

Two. Ryanair’s permitted-items page states that power banks are limited to a maximum of two per passenger and are included within the overall limit of 20 spare lithium batteries, so two power banks plus 18 spare batteries is the most anyone can carry. Each must not exceed 100Wh. They travel on your person or in the under-seat cabin bag, never in checked baggage and never in a bag in the overhead lockers.

Can I use a power bank on a Ryanair flight?

Yes, except during taxi, take-off and landing, or when the crew tell you otherwise. Ryanair’s page states that power banks may be used to charge personal electronic devices outside those phases. What is banned at any time is recharging the power bank itself, including one power bank charging another. Ryanair seats have no USB or AC power, so the bank is the only way to charge a phone on board.

What is Ryanair’s power bank watt-hour limit?

100Wh, flat. Ryanair’s page says devices or batteries exceeding 100Wh are not permitted in either cabin or checked baggage, and offers no approval tier for 100 to 160Wh. Read the Wh on the case or convert: Wh = mAh x 3.7 / 1,000. A 10,000mAh bank is about 37Wh, 20,000mAh about 74Wh, 27,000mAh about 100Wh, and 30,000mAh, about 111Wh, cannot fly on Ryanair.

Can I put a power bank in the overhead locker on Ryanair?

No. Ryanair states that spare lithium batteries and power banks cannot be placed in cabin baggage stored in the overhead lockers, and must be carried on your person or in the under-seat cabin bag stowed under the seat in front. If you paid for Priority and a 10 kg wheeled bag, the power bank comes out of that bag and into the small one before boarding.

Can a power bank go in checked baggage on Ryanair?

No. Ryanair’s rule is that spare lithium batteries and power banks are carried in the cabin only, on your person or in the under-seat bag, and devices or batteries over 100Wh are barred from checked baggage as well. If your wheeled cabin bag is put in the hold at the gate, which happens on full flights, take the power bank out first and keep it with you.

Does Ryanair allow smart bags with a battery?

Only with the battery removed or small. Ryanair’s page says a smart bag with a non-removable battery over 2.7Wh is not permitted on board, and a removable battery must not exceed 100Wh and must be carried in your small cabin bag or on your person. The bag itself cannot go in the hold with the battery still inside. Once removed, the battery counts as one of your two power banks if it can charge other devices.
