Can I fly home with a power bank or batteries from Daiso Korea?
A power bank must go in your carry-on, never your checked bag. Under rules Korea applied from April 20, 2026, you can carry up to two power banks of 160 Wh or less, and you may not charge them from the seat outlet or use them to charge another device during the flight. Power banks over 100 Wh need airline approval, and over 160 Wh are not allowed.
What to do now
- Find the Wh rating on the power bank (or work it out from mAh and volts).
- Pack the power bank in your carry-on bag, not your checked bag.
- Bring no more than two, each 160 Wh or less; get airline approval for any over 100 Wh.
- Do not plug it into the seat outlet or use it to charge your phone during the flight.
Capacity (100 Wh and 160 Wh are the thresholds), number (two at most) and where it is packed (carry-on only) decide it. Airlines can set stricter rules.
Who owns the resolution
Korea's transport ministry sets the rule, airport security enforces it, and your airline can add stricter limits.
Evidence to prepare
- The power bank's label showing Wh (or mAh and voltage)
- Airline approval, for any power bank over 100 Wh

I need practical help with a Daiso Korea issue. The policy question: Can I fly home with a power bank or batteries from Daiso Korea? Useful context I found: A power bank must go in your carry-on, never your checked bag. Under rules Korea applied from April 20, 2026, you can carry up to two power banks of 160 Wh or less, and you may not charge them from the seat outlet or use them to charge another device during the flight. Power banks over 100 Wh need airline approval, and over 160 Wh are not allowed. My specific situation: [Describe what happened, including dates and messages shown] The outcome I want: [Refund, verification, appeal, account recovery, explanation, etc.] Important constraints: [Country, deadline, booking/account status, documents already submitted, budget, or other limits] Please: 1. Identify any missing facts you need before reaching a conclusion. 2. Separate platform policy, local law, and your own inference. 3. Give me the safest next steps in priority order. 4. Use current official sources where possible and flag anything that may have changed. 5. Draft a concise message I can paste to customer support. 6. Do not invent account access, guarantees, refund rights, or legal conclusions.
Why this policy exists
Korea's Ministry of Land, Infrastructure and Transport rules effective April 20, 2026 (Korea.net), based on standards ICAO approved on March 27:
· Up to two power banks per passenger, each 160 Wh or less.
· All power banks go in carry-on, whatever their capacity. None may be checked.
· No charging the power bank from the aircraft's power outlet, and no using it to charge another device in flight.
· Over 160 Wh: not allowed at all.
Incheon Airport's FAQ adds that lithium batteries from 100 to 160 Wh need airline approval, and that the number allowed below 100 Wh can vary by airline.
The capacity in Wh is printed on the power bank. If only mAh is shown, Wh = mAh × volts ÷ 1,000; for example, 10,000 mAh at 3.7 V is 37 Wh. These rules are about lithium power banks; for loose batteries such as AA cells, check your airline's rules.
