How many power banks can you take on a flight from Finland?
Rules for power banks and other lithium batteries.
Short answer
Finavia says a passenger may carry at most two power banks, each with a maximum energy content of 100 Wh, in hand baggage. Power banks, spare batteries and e-cigarettes must not go in checked baggage because of the fire risk. Taloustaito reported in June 2026 that about 34,000 to 36,000 power banks are removed from checked bags in Finland every year. A removed power bank can delay your whole bag.
Why
- Finavia's packing page sets the limit of two power banks of 100 Wh.
- Traficom and Finavia remind passengers that power banks belong in hand baggage.
- Taloustaito reports 34,000 to 36,000 power banks removed from checked bags each year.
Details
A 20,000 mAh power bank is about 74 Wh. If the capacity is not marked, security may refuse it.
Tip
If your cabin bag is moved to the hold at the gate, take the power bank out first.
What may differ
Airlines may ban using power banks on board. Check your airline's rules.
Common misconception
It is safer to pack power banks in your suitcase.
What actually happens
They are banned in checked bags. Keep them in your hand baggage.
