While power banks come in many different styles, colors and sizes, one of the primary differentiators is their capacity. Measured in mAh (milliampere-hour), their capacity determines the amount of charge they can hold ? and consequently, the power they can supply your devices. While it’s hard to determine an exact number of charges, the general rule of thumb is that the higher the mAh rating, the more capacity the power bank holds.
