Are Power banks allowed on planes?
Answer A: It will depend on the capacity in Wh (watt hours) but most commercially available ones should be OK. The IATA guidelines say that under 100Wh (multiply Ah x V to get Wh) is OK to bring on board and in cargo if installed in equipment. If they are loose spare batteries you can bring as many in carry on but not in the hold. Between 100-160Wh same applies but you are restricted to 2 spare loose batteries and again not allowed to check in. If over 160Wh you have to declare it and it has to be packed in cargo under the Dangerous Goods guidelines.Most airlines follow the IATA guidelines.
Answer B: only restriction I found was that the battery must be under 100Wh. Keep in mind that you have to validate the rules for any Airlines you will be flying and the airport rules if they are not in the US. It must be in hand luggage and not in a suitcase in the hold.
Answer C: They may be found in (at least) IATA documentation and also a number of courier companies and most battery manufacturers have advice documents. Removable batteries must be carried in carry-on luggage with the exception mentioned below. Having batteries in carry=on makes sense – would you rather have a fire in a cargo hold or an overhead locker. There is an upper limit to the amount of Lithium metal that may be carried. Some manufacturers provide specific mass of Li per battery. Otherwise they have a linear conversion between Watt hour of battery (Vbat x mAh.) and Li metal.
Answer D: It’s fine in your carry on-luggage only. Batteries are not allowed in check-in luggage, only in carry on-luggage where they can be monitored. Here are the rules for batteries:
In order to ensure air transport safety, FAA,IATA, Airport has issued relevant regulations to regulate air passengers and crew members carrying power banks on to flights. The rated energy of power banks which can be carried on board is restricted and identification method for rated power has also been specified. For details, see the “Announcement of Rules for Air Passengers Carrying Power Bank onto Flights”.

Summary: If you want take a power bank onto a plane you should follow below instructions of security staff during the security check. Here is the Rules in china:
“Announcement of Rules for Air Passengers Carrying Power Bank onto Flights”
1. Power bank must be carried for personal use.
2. Power bank must only be carried in hand luggage or carried around. It is not allowed to carry power banks in checked luggage.
3. If the rated power is less than 100WH, power banks can be carried without approval; power banks with the power between 100WH and 160WH can be carried after approval of air carrier. However, each passenger is only allowed to carry no more than two power banks.
4. It is not allowed to carry the power banks with power higher than 160WH or the power banks without identified rated power and with rated power unable to be worked out with the marked parameters.
5. Passengers are not allowed to use power banks to charge electronic devices during the course of the flight. Power banks must be switched “Off” during the course of the flight. Above mentioned regulations are also applicable for crew members. This announcement shall take effect from the date of its promulgation. Attachment: Calculation methods for the rated power of power banks.
Calculation methods for the rated power of power banks
If the rated power is not directly marked, the calculation methods are as follows:
1. If Nominal Voltage (V) and Nominal Capacity (Ah) are given, the rated power can be calculated as follows:
Wh=V×Ah
Nominal Voltage and Nominal Capacity are usually marked on power banks.
2. If only milliampere (mAh) is given, please divide the number by 1,000, and you get ampere-hour (Ah).
For example: Nominal Voltage is 3.7 and Nominal Capacity is 760mAh, and then you get the rated power:
760 mAh÷ 1000 = 0.76Ah
3.7V×0.76Ah=2.9Wh

My 11,000 mAh 5V power bank was confiscated at Beijing airport, even though 5*11,000/1000=55Wh, far below the limit. However, it has two outputs (1A/2A); could it be that these were added up to give (5+5)*11,000/1000=110Wh, which exceeds the limit? If so, is that a rule?

Generally the nominal voltage should be around 3.7V, it’s nothing related to the number of output ports, so it’s supposed to go for 11*3.7 = 40.7 Wh which does definitely not exceed the rule, I wonder it’s confiscated for other reasons, I used to travel with a 15000 mAh power bank and pass the security check at Beijing airport without a hitch.

That is what I thought (except for the 3.7 V; I think the nominal [output] voltage must be taken, i.e., 5 V). Must have been an error of the “specialist” agent who was consulted by the officer who checked my baggage [and I was not sure enough of the limits to start a discussion]; the power bank had been passed without comment when we entered China.

Had the same happen in Beijing for a small battery – they required a CE approval stamp in order to allow them and the one I had was merchandise without the stamp…

Mine was confiscated in Beijing because the writings on the powerbank has faded and they couldn’t decide the capacity. Chinese airport is really strict. Because i didn’t have the same problem in Turkey and Qatar.

Indigo Air did not allow any power bank to be carried in the aircraft neither in hand luggage or check in baggage. Yesterday my husband had to abandon his 10000 mAh power bank at the Delhi airport, which he bought two weeks earlier only for this travel.

No discussion about size
And you aren’t supposed to have them in the hold luggage!

Sorry to hear that, actually I just took a China Airline flight and no troubles encountered when my EasyAcc 20000mAh power bank was checked by the security.
