One thought on “Top Questions about Power Bank–Part 1

  1. My tablet can power devices over USB. It can also be charged over USB. When using a power bank does charging stop when the charge on each side is equal, meaning I need a Power Bank charged to twice the capacity of the tablet in order to fully charge the tablet? If not, how does the power bank or tablet know what it is doing?
