Philippine Airlines モバイルバッテリー飛行ポリシー。

短い回答

Philippine Airlines is tracked from its official restricted-items dangerous-goods page model: power banks under 100 Wh are allowed on board with a maximum of two per passenger, are allowed in carry-on and not checked baggage, must not be placed in overhead bins, must stay on the passenger, under the seat, or in the seat pocket, must have a clearly indicated capacity label, cannot be charged throughout the flight, and cannot be used to charge devices during taxi, takeoff, or landing. The same official lithium table also exposes spare rechargeable lithium and sodium-ion battery carry-on-only handling, 20 spare batteries below 100 Wh, two 101-160 Wh spare batteries with airline approval and check-in declaration, and a ban above 160 Wh.
