Check if an external battery is suitable for air travel
The regulation specifies that the nominal capacity must be less than 100 Wh (Watt-Hour). That is to say: any power bank with a capacity lower than 27000 mAh (at 3.7V) is apt to be carried on an airplane as carry-on luggage. - See the TSA regulations -
How is the nominal capacity calculated in Wh?
Normally, the Travel power bank specification sheet usually indicates its nominal capacity in Ah and Wh but, if you can not find it, you can calculate it for yourself:
As you already know, a power bank consists of a set of lithium-ion batteries of a certain capacity and a voltage between 3.6 Volts 3.8 Volts.
To know the nominal capacity in Watt-hour (Wh) you must multiply the total capacity of the power bank indicated in mAh by this voltage and divide by 1000:
Rated capacity (Wh) = (mAh x V) / 1000
For example: An external battery with a capacity of 20000 mAh and a voltage of 3.7V, the nominal capacity will be:
Rated capacity = (20000 mAh x 3.7V) / 1000 = 74 Wh <100 Wh
