The actual (physical) capacity of the battery cell is 8400 mAh. Practically, however, can not be any external battery lossless transfer all this power to the mobile device battery, loss of energy always arises in the necessary drive voltage from 3.7 V to 5 V, on the transition of contact resistance less than 100% efficiency saving energy in the battery being charged device , due to temperature conditions, due to higher charging current and the like. Generally, the constant energy can move from the external battery to the battery of the charging device with efficiency between approx. 85 and 70% depending on these conditions.
