Ryanair & Aer Lingus Power Bank Rules – What’s Allowed & Our Top Travel Picks (2025 Guide)
✈️ Can I Bring a Power Bank on a Plane in Ireland?
Yes – both Ryanair and Aer Lingus allow passengers to bring power banks in carry-on luggage only.
They’re classed as lithium-ion batteries, which aviation safety rules forbid in checked bags because of potential fire risk.
If you’re flying from Ireland to Europe or further abroad, make sure your power bank meets each airline’s capacity limit before travelling.

🔢 How to Calculate Watt-Hours (Wh)
If your power bank only lists mAh, use this quick formula to check if it’s under the 100 Wh limit:
(mAh ÷ 1000) × 3.7 = Wh
Example: 20 000 mAh × 3.7 ÷ 1000 = 74 Wh ✅ Airline-safe
Any power bank under 100 Wh is approved for carry-on use on Irish flights.
💡 Traveller Tips Before You Fly
- Keep your power bank in hand luggage only – never in checked bags.
- Charge it to around 50 % before security (you might be asked to switch it on).
- Protect the ports – store it in a pouch or case to prevent short circuits.
- Label the capacity (mAh / Wh) clearly to avoid confusion at security checks.
- Switch it off during take-off and landing if requested by crew.
