Eleanor StoneRyanair's tightened restrictions on power banks caught thousands of UK passengers off guard in spring 2026 — with devices being confiscated at airport security before boarding across British airports. Understanding exactly what the rules say, and what legal options you have when things go wrong, is essential before your next flight.
What Ryanair's Power Bank Rules Actually Say
Ryanair follows International Air Transport Association (IATA) guidelines on lithium-ion batteries. The central rule: power banks are classified as spare lithium batteries and are prohibited in checked hold luggage entirely.
In the cabin, passengers may carry power banks up to 100 watt-hours (Wh) without special permission — this covers the vast majority of consumer devices sold in the UK. Devices between 100Wh and 160Wh require explicit airline approval before travel. Anything above 160Wh is banned outright.
Critically, power banks must be stored in your small personal bag or on your person — not in overhead lockers during taxi, take-off, or landing. They must be individually protected against short circuits: kept in their original packaging, with terminals taped over, or stored in a separate plastic pouch.
The safety rationale is clear: lithium cells can enter thermal runaway — a rapid and uncontrollable temperature rise that can trigger fire, explosion, and toxic fumes. A smouldering battery in the hold is invisible to crew until it is far too late.
What Happens When Your Power Bank Is Confiscated at the Gate
If security determines your power bank exceeds the permitted watt-hour rating, or find it improperly stored, they can confiscate it on the spot. Unlike checked-baggage items that may be rerouted or repackaged, a device seized at the boarding gate is typically not returned — ever.
This leaves passengers facing a practical loss: an item worth £20 to £200 or more, seized minutes before a flight, with no receipt and no recourse counter in sight. The question that is now reaching consumer rights lawyers in growing numbers is simple: can I claim this back?
Your Rights Under UK Aviation Law
UK aviation consumer rights are governed by the UK261 framework — Britain's post-Brexit equivalent of EU Regulation 261/2004 — covering compensation for delays, cancellations, and denied boarding.
Power bank confiscations for safety reasons, however, fall under what regulators classify as "extraordinary circumstances." Airlines can argue they acted on legitimate safety grounds, which typically limits your direct compensation claim against Ryanair itself under UK261.
But that does not leave passengers with nothing:
Wrongful confiscation claims: If your device was clearly within permitted limits — a 74Wh power bank confiscated in error, for instance — you may have grounds for a claim against the airline or airport authority for the replacement value of the item.
Alternative Dispute Resolution (ADR): Ryanair participates in an approved ADR scheme. If Ryanair's customer services team does not resolve your complaint within eight weeks, you can escalate to the scheme's independent adjudicator without going to court.
The UK Civil Aviation Authority: The UK CAA is the official regulatory body overseeing passenger rights in Britain. It publishes guidance on what to do when airlines fail to respond appropriately, and can intervene in systemic complaints against carriers.
How to Convert mAh to Wh — Before You Pack
Most passengers know their power bank's milliamp-hour (mAh) rating, printed on the device casing. But airport security checks the watt-hour figure. Converting is straightforward.
Divide the mAh rating by 1,000, then multiply by the battery voltage — typically 3.7 volts for standard lithium-ion cells:
- 20,000mAh × 3.7V ÷ 1,000 = 74Wh — well within Ryanair's limit
- 26,800mAh × 3.7V ÷ 1,000 = 99.2Wh — just under the 100Wh threshold
- 30,000mAh × 3.7V ÷ 1,000 = 111Wh — above the limit, requires airline approval
Many reputable manufacturers now print the Wh rating directly on the device or its box. If yours does not, run the calculation at home — not at the security queue.
When Should You Seek Legal Advice?
For a standard £30 power bank, formal legal proceedings are unlikely to be proportionate. However, there are circumstances where consulting a consumer rights solicitor is well worth the call.
If your confiscated device was specialist or professional equipment — a high-capacity charging unit for medical devices such as a CPAP machine or insulin pump, for example — the financial stakes are considerably higher. If the confiscation caused you to miss a connecting flight, forfeit a non-refundable hotel booking, or suffer measurable business losses, you may have a claim that goes well beyond the value of the device itself.
A consumer rights solicitor can assess whether Ryanair followed its own terms of carriage correctly, whether security staff applied the rules lawfully, and what level of compensation is realistic to pursue through the courts or ADR.

Five Things to Do Before Your Next Ryanair Flight
- Check your power bank's watt-hour rating at home, not at the airport.
- Keep it in your small personal cabin bag — never in hold luggage.
- Protect the terminals with the original case, tape, or a dedicated pouch.
- Save a screenshot of the product specification page on your phone.
- If confiscated despite being compliant, note the officer's name, the time, and request a written receipt — this is the foundation of any claim.
