✈️ Airlines and Baggage Rules Mandatory Carry On Luggage Rule

Power Bank Carry-On Limits and Checked Baggage Rules

Due to fire risks, power banks are strictly prohibited in checked luggage and must be carried into the cabin. The ICAO standard applied on 27 March 2026 unified the allowance at two per passenger regardless of capacity, and a pack between 100Wh and 160Wh needs prior airline approval on top of that.

As of 2026-08-24

This is the Airlines and Baggage Rules item that applies wherever you are going. The 4 checkpoints below can only be settled properly before you leave — put them off and you queue at an airport desk or spend the first day on them instead. Work through them once and nothing has to be reopened.

Key checkpoints

Check the Wh rating printed on the battery casing, or calculate it by multiplying mAh by voltage (V) and dividing by 1,000 if only mAh is displayed.
Pack all power banks in your carry-on luggage, as packing them in checked bags will trigger security inspection, baggage opening, and confiscation.
The per-passenger limit was unified at two by the ICAO standard applied on 27 March 2026, regardless of capacity — the earlier "five under 100Wh" allowance no longer applies.
Recharging a power bank in flight is prohibited under the same standard — keep it where you can reach it, such as the seat pocket, and tell a crew member immediately if it swells or gets hot.

What to do before departure, in order

Two rules decide the order. First, anything with a deadline — pre-registration, bookings, documents to be issued: miss the cut-off and there is no substitute. Then whatever also works locally, which costs little to postpone.

Most of the items above can only be done before you leave. After arrival, patchy connectivity and opening hours make them harder, so finish what you can while you are still at home.

Baggage rules covered by this article

2 items named in this article are also governed by airport screening and airline rules. Check the cabin/checked verdict before you split your bags. The verdicts below are about what may fly; an item the destination country bans outright is a separate matter.

The rules behind those baggage verdicts

The baggage verdicts above follow from 2 Korean rules listed below, named in the original Korean because that is how they are indexed at the national law database. These are the rules themselves, not an airline summary — when screening staff disagree, this is the text that decides. What they settle is whether an item may fly; an item the destination country bans outright is governed by that country's own rules.
