主な制約
数量
Maximum two power banks per passenger or crew member.
ワット時制限
Power banks: plan around the 2026 passenger-facing 100 Wh limit. Generic 100-160 Wh lithium-battery approval language is not shown as a power-bank allowance unless the airline source explicitly says so.
機内持込
Carry-on only; store under the seat, in a seat-back pocket, or in another designated accessible location rather than overhead bins.
受託手荷物
Power banks are strictly prohibited in checked baggage.
“From April 24, 2026, MLIT tells passengers not to put power banks in checked baggage, to carry them on board, keep them to 160 Wh or less, protect each power bank against short circuits, avoid overhead compartments, carry up to two per passenger, and not charge or use power banks during flight.”
