Korean Air power bank rules (2026)
Korean Air doesn’t state a Wh limit or a number of power banks, so the worldwide rules apply: up to 2 per person, each up to 100 Wh, in your carry-on only. You can’t use it or charge it on board. These rules apply since 26 January 2026.

Korean Air power bank questions

Korean Air doesn’t state a number of power banks, so the worldwide limit applies: 2 per person (ICAO). From Korean Air’s page: Release refers to carry-on rules; numbers not stated.
Can I bring a 20,000 mAh power bank on Korean Air?
Yes. At 3.7 V a 20,000 mAh power bank is about 74 Wh, under the worldwide 100 Wh limit (Korean Air doesn’t state one). Keep it in your carry-on.
Can I use my power bank on a Korean Air flight?
No. Korean Air doesn’t allow using a power bank on board, and you can’t recharge it on board either.
