You may similar with portable power bank for cellphone. But do you know power bank charger capacity?  Simple, Power Bank capacity refers to how much charge is inside a power bank battery.

It is measured in mAh or milliamps per hour.

When a power bank android is charging a phone, some of the charge is lost in the transfer of power. In simple terms, it takes energy to transfer energy. So, the real capacity is about 62.9% of the battery capacity listed on the outside of a Power Bank that has a high quality battery.

For example, a Power Bank with a quality battery at 2200mAh has a real capacity of 1380mAh. 820mAh is lost in the transfer of energy.
