When the user charges the first and second battery units BT1 and BT2 of the portable multi power supply control pack device 100 of the present invention, the power supply control pack main body 2 and the control jack gender 4 The USB cable 8 of the USB charger 10 is plugged into the USB input 12 of the control jack gender 4 and charged.

The slave terminal line SL and the shunt terminal line SH of the first jack connector J1 shown in FIG. 5 are opened and the second terminal An active "high" state due to the battery voltage of the battery section BT2 is applied to the base of the transistor Q1 of the switching control section 24 to turn on the transistor Q1.

The switch pair RS of the interlocking switch section 22 of the series-parallel switching circuit section 20 maintains the initial position of the nominal a selection terminal. When the transistor Q1 is turned on, Quot; a " to " b " As a result, the serial-parallel switching circuit unit 20 is formed as a circuit loop in which the first and second battery units BT1 and BT2 are connected in parallel.

Therefore, by the path of the USB jack 8, the USB input 12 of the control jack gender 4, the lead 16, the second jack portion JP2, and the second jack connecting portion J2 of the power control pack main body 2 A charging voltage of 5 V is inputted and a constant voltage of 4.2 V is inputted through the constant voltage unit 30 to charge the first and second battery units BT1 and BT2 which are in a parallel connection state.
