Every power bank has a socket meant for electricity input. This specific electrical power comes from a USB socket on your computer system, but can recharge more rapidly when using a wall socket adapter. We generally witness External battery chargers utilize a Mini or perhaps Micro-USB plug for charging, and standard USB plugs for discharging. Occasionally the input and output plug are the same, but it is best to stay away from these battery chargers. Always check the instructions for specific directions if you are not able to locate a visibly marked input plug.
