Ryanair & Aer Lingus Power Bank Rules – What’s Allowed (2026 Guide)
✈️ Can I Bring a Power Bank on a Plane with Irish Airlines?
Yes, both Ryanair and Aer Lingus allow power banks, but they must be in carry-on luggage only.
Power banks are treated as spare lithium-ion batteries, so they are not allowed in checked baggage due to fire risk.
✅ Quick Answer (Scan This)
- Carry-on only: never pack a power bank in checked luggage.
- Size limit: most airlines allow up to 100Wh per power bank.
- Ryanair: up to 20 spare batteries/power banks (≤100Wh each), protected against short-circuit.
- Aer Lingus: power banks are spare batteries; Aer Lingus limit is 4 spares up to 100Wh per person (operator variation).

🔢 How to Calculate Watt-Hours (Wh)
If your power bank only lists mAh, use this quick formula to confirm it’s under the 100Wh airline limit:
(mAh ÷ 1000) × 3.7 = Wh
Example: 20,000 mAh × 3.7 ÷ 1000 = 74 Wh ✅ Airline-safe
Rule of thumb: 10,000–20,000mAh power banks are typically well under 100Wh and are the easiest “no-stress” sizes for flying.
💡 Traveller Tips Before You Fly
- Carry-on only: never put a power bank in checked luggage (even “by accident”).
- Be able to turn it on: security or staff may ask you to power it up.
- Protect the ports: store it in a pouch/case or separate bag to prevent short-circuits.
- Keep the label visible: capacity (mAh/Wh) should be printed on the unit.
- If your cabin bag is gate-checked: remove your power bank and keep it with you in the cabin.
Ryanair-specific notes
- Don’t use a power bank to charge devices during taxi, take-off, or landing.
- Don’t store power banks in an overhead locker — keep them under the seat or on your person.
- Spare batteries/power banks must be individually protected (pouch, separate bag, taped terminals, or original packaging).
🔋 What Capacity Should You Bring?
- 10,000mAh: best for city breaks/weekends (lighter, pocket-friendly).
- 20,000mAh: best all-rounder for travel (heavy phone use, maps, photos, 2 devices).
- Near the limit (~26,800–27,000mAh): technically closest to 100Wh, but not necessary for most travellers.

❓ FAQ
Can I put a power bank in checked luggage?
No. Power banks/spare batteries must be carried in hand luggage. If your carry-on is taken at the gate and put in the hold, remove the power bank first.
How many power banks can I bring?
Ryanair: up to 20 spare batteries/power banks (≤100Wh each).
Aer Lingus: power banks are spare batteries; Aer Lingus operator variation limits passengers to 4 spares up to 100Wh per person.
Can I bring a power bank over 100Wh?
Usually no. Some airlines may allow 100–160Wh with airline approval, but rules vary. Aer Lingus guidance notes a maximum of two spare batteries in the 100–160Wh range.
What if my power bank doesn’t show mAh or Wh?
You’re increasing the odds of hassle. If staff can’t verify capacity, it’s more likely to be refused at security.
🧳 Summary
Both Ryanair and Aer Lingus allow power banks up to 100Wh in carry-on luggage only. The simplest travel choice is a 10,000–20,000mAh power bank: well under the limit and enough for real-world travel use.
