When you are planning for a journey or business trip, this question must pop up frequently. Is power bank allowed on airplane? Actually the answer varies.
If the power bank is in the carry-on baggage in the aircraft cabin, and the capacity is below 100 Wh, which is equivalent to less than 27,000 mAh, then the answer is yes. A reminder is that the voltage of power banks should be 3.6-3.85 V.
In accordance with the International Civil Aviation Organization’s (ICAO) latest technical instructions for the safe transportation of dangerous goods by air, the power banks of more than 27,000mAh can’t be carried in the cabin, and must pass through the approval of the airline concerned. Besides, in the airport security types of certain countries, such as China and India, power banks of 101-160Wh, that is more than 27,000mAh, are prevented from carrying on the airplane directly.
These regulations take effect last August, so everything you know about carrying power banks on the airplane should be updated now.
Since the luggage weight of carry-on is also limited, it’s commendable to bring a power bank of large capacity with compact design. That is to say, power banks of Li-polymer battery cells are preferred.
