LongJiang Airlines モバイルバッテリー飛行ポリシー。

短い回答

LongJiang Airlines publishes an official lithium-battery and dangerous-goods safety notice through its website/CMS. The notice says power banks are treated as spare lithium batteries, each power bank must not exceed 160 Wh, each passenger or crew member may carry no more than two power banks regardless of rated energy, and onboard power banks must remain switched off and may not be used to charge electronic devices. Spare batteries must be protected against short circuit and carried only in hand baggage.
