How many times can I charge My Smartphone with a Power Bank?
Many of us make the mistake of believing that the mAh exposed on the capacity of a power bank is equivalent to 100% of the charge that they can provide to a smartphone or tablet. It is not so. Actual capacity varies from 65% (worst case) to 80% (best case): to know the real charge capacity you should know the Wh (watt-hours) and perform the calculation: Wh / 5V.
Since 5V is equivalent to the voltage required by the USB standard. If you do not know the Wh of a Power Bank, simply to know the real capacity of recharge just carry out the calculation: mAh * 0.7.
For example, a 3000mAh power bank guarantees a recharge of at least 2100mAh, a 15,000mAh battery guarantees 10,500mAh and so on.
