Please note: The actual (physical) capacity of the battery cell is 4.400mAh. Practically, however, not from any external battery lossless transfer all this power to the mobile device battery, loss of power always arises in the necessary drive voltages from 3.7V to 5V on the transition of contact resistance of less than 100% efficient energy storage devices in battery being charged, 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 being charged device effective between approx. 85 and 70% depending on these conditions.
