Power banks have become a regular travel essential, especially on short European flights where phones handle boarding passes, maps, payments and airport updates.
So, can you take a power bank on Ryanair? Yes, you can take a power bank on a Ryanair flight in 2026, as long as it follows the airline’s battery rules. Additionally, EASA says power banks must travel in carry-on baggage, and never checked baggage.
Key Rules: Can You Take a Power Bank on Ryanair?
Under the Ryanair power bank rules for 2026, a power bank can be carried if it:
- Does not exceed 100Wh
- Travels in cabin baggage only
- Is protected from damage and short circuits
- Stays in your small bag under the seat, or on your person
- Is not placed in checked luggage
Many 10,000mAh and 20,000mAh phone power banks fall below 100Wh, but check the label before you travel. If the watt-hour rating is missing or unclear, airport staff may not accept a rough estimate.
Can You Pack a Power Bank in Checked Luggage on Ryanair?
No. EASA says spare batteries and power banks must travel in carry-on baggage, never in checked baggage. Ryanair also places power banks in the cabin-bag category.
The reason is safety. Lithium batteries can overheat if damaged, crushed or short-circuited. If that happens in the cabin, crew can respond quickly. In the hold, the risk is harder to manage.
Before checking in a suitcase, move power banks, loose lithium batteries and removable smart-bag batteries into your cabin bag.
What Size Power Bank Is Allowed on Ryanair?
Ryanair allows spare lithium batteries and power banks up to 100Wh each. Devices or batteries over 100Wh are not allowed in the cabin or the hold, apart from specific mobility equipment rules.
Many power banks show capacity in milliamp hours rather than watt hours. You can estimate it with this formula:
Wh = mAh x V / 1000
For example, a 20,000mAh power bank at 3.7V equals about 74Wh. A 30,000mAh unit may be close to or above 100Wh, depending on voltage. Always rely on the printed rating, not the product name.
Do not travel with a swollen, cracked, leaking or unusually hot battery pack.
Where Should You Keep It in Your Cabin Bag?
Ryanair says power banks should be placed in the small cabin bag stored under the seat in front of you, or kept on your person. An organised under-seat bag is safer than a packed overhead suitcase.
A good Ryanair power bank cabin bag setup keeps your charger easy to reach. Keep it away from coins, keys, liquids and sharp items.
Useful packing habits include:
- Store the power bank in a side pocket or tech sleeve
- Keep charging cables in a small organiser
- Cover exposed terminals if needed
- Keep the label visible for inspection
Ryanair Lithium Battery Rules: Safety Tips for Travellers
The Ryanair lithium battery rules reflect a real concern with lithium battery fires, which can spread quickly if a cell fails.
EASA says power banks should not be used to charge other devices during the flight. Ryanair also says spare lithium batteries, including power banks, should not be used to charge or power devices during taxi, take-off or landing.
For a smoother trip:
- Charge your phone before boarding
- Carry only the power banks you need
- Do not use damaged batteries
- Keep the power bank within reach
- Follow cabin crew instructions
If your power bank starts heating, swelling, smoking or smelling odd, tell the crew immediately.

Choosing a Ryanair Approved Cabin Bag for Tech Essentials
A well-designed Ryanair approved cabin bag can make travelling with chargers and electronics easier. For short European trips, many passengers prefer an under-seat backpack or compact bag with compartments for tech and travel documents.
When choosing a bag, look for:
- An easy-access front pocket
- A padded sleeve for electronics
- Internal zip compartments
- Lightweight construction
- A shape that fits neatly under the seat
A cabin bag should do more than fit the size rules. It should help you move through security, boarding and the flight without digging for the item you need most.
Frequently Asked Questions:
1. Can I take a 20,000mAh power bank on Ryanair?
Usually, yes. Many 20,000mAh power banks are under 100Wh, but check the printed Wh rating before you fly. If the rating is missing, choose a clearly labelled charger.
2. Can I take two power banks on Ryanair?
Ryanair allows spare lithium batteries and power banks within its published limits. Make sure each one is under 100Wh, protected from short circuits, and carried in your small cabin bag.
3. Can I use my power bank during the flight?
Avoid using it unless cabin crew say it is allowed. Ryanair restricts use during taxi, take-off and landing, and EASA advises against charging devices with power banks in flight.
4. Can a power bank go in my overhead cabin suitcase?
Ryanair says power banks should not be placed in cabin baggage loaded into the overhead locker. Keep yours under the seat or on your person.
5. What happens if my power bank is over 100Wh?
Ryanair states that devices or batteries over 100Wh are not permitted in the cabin or hold for normal passengers. Leave it at home and pack a compliant charger instead.
