Power bank with automatic detection for charging capability

A power bank with automatic detection for charging capability, comprising:

• a battery unit used for storing and releasing electricity;
• a control unit connected to the battery unit, when the battery unit is charged or discharged, a charged process or a discharged process of the battery unit being controlled through the control unit, the control unit having a function of controlling a voltage condition of the battery unit during the charged process or the discharged process of the battery unit;
• an input unit connected to the control unit, the input unit being used for being connected with an external power source, so that an external current entering the battery unit for proceeding to charge the battery unit;
• at least one output unit connected to the control unit, the at least one output unit being used for being connected with an external device, and the at least one output unit providing electric power in the battery unit for the external device;
• a starting unit connected to the control unit and the at least one output unit, the starting unit being in a grounded state to form a current loop which is provided for the battery unit to proceed to discharge;
• and
• a detecting unit connected to the control unit and the at least one output unit, the detecting unit being used for sensing whether a signal is transmitted from the at least one output unit, so that the control unit is able to control the battery unit to enter a discharged state;
• wherein the power bank with automatic detection for charging capability is connected to the external device by virtue of a charging cable with a ground signal function or the charging cable without the ground signal function to charge the external device.
