Are power banks allowed on plane?

When travelling by air,especially going abroad, we usually bring a power bank in our package in case that our phones don't have enough power for calling , taking photos or watch videos online.


But do you know the airplane restrictions about power banks ?

According to the air restriction about lithium batteries in USA ,

  • Limitation for Spare Batteries and Portable Battery Supply Devices (Power Bank) : Carry-on baggage only and do not place in check-in baggage!

  • The battery terminals are protected from short circuits, e.g. by placing each battery in its own protective case, by taping over exposed terminals or by placing in plastic bag. Although there’s no quantity limitation on lithium-ion batteries that are under 100Wh, the number of spare batteries must be "reasonable" and for personal use. If the power bank itself does not list specification, it will not be allowed for carriage.
Notice : The power bank you bring must have a button for you to turn on

  • With the Approval of the Airlines : Maximum two 100Wh-160Wh spare lithium-ion batteries (including Portable Battery Supply Device and Power Bank) per person may be carried in a carry-on baggage on board. Any lithium-ion battery that is over 160Wh is prohibited aboard the plane. Under UN Manual of Tests and Criteria, Part III, subsection 38.3: Wheelchairs/Mobility Aids with Lithium, Security-Type Equipment, and Portable Medical Electronic Devices.
Notice : the normal voltage of a power bank is 3.7V, so the max capacity of power banks you could bring to an airplane is 27000mAh - 40000mAh 

When travelling , 10000mAh -20000mAh is enough and more suitable to use. For a power bank with good quality, it could charge your phones 3-4 times , and only a night is needed to recharge it . And the size is much more portable being put in your backpack when you are out.
