The labelled capacity on the power bank x 3.7 / output voltage of the power bank x 0.85 / the battery capacity of the of the drive = total number of charges for the device. Such as iPhone X has a battery size of 2,716mAh, and this power bank, it is 10400mAh capacity. It may charge your iphone x about N times. N= 10400mAh x 3.7 / 5 x 0.85 / 2716mAh = 2.4 times So it may charge iPhone X 2.4 times. Note: you cannot use this formula if you are charging your device with a USB-C PD port in a charging port.
