Korea’s April 2026 rules limit passengers to two power banks, each no more than 160 Wh. Using or recharging a power bank on board is prohibited. Capacity above 100 Wh requires airline approval where accepted.
Capacity and quantity are separate checks
A small battery still counts as one power bank. Do not add two ratings together to decide the capacity of one device; check each device and then the total number.
Check your operating airline too
Some carriers cap power banks at 100 Wh even where local rules permit a higher capacity with approval. Keep the devices accessible and follow staff instructions at the departure airport.
