When the current number of team members is not consistent with the preset number of team members, the MCU sends an alarm signal to the alarm module to issue an alarm; a power bank shell, the power bank shell is provided with a self-locking scroll mechanism, and the locking and releasing states of the flexible solar panel are controlled by a locking button.

[0007] Furthermore, the solar secondary charging circuit includes a flexible solar panel, a supercapacitor, a supercapacitor overvoltage switch protection circuit, and a voltage stabilizing circuit. One end of the flexible solar panel is grounded, and the other end is connected to the supercapacitor overvoltage switch protection circuit. One end of the supercapacitor is connected to the supercapacitor overvoltage switch protection circuit, and the other end is connected to the voltage stabilizing circuit. One end of the voltage stabilizing circuit is connected to the battery charging circuit.

[0008] Furthermore, the overcharge and over-discharge protection circuit includes a battery monitoring circuit and a dual MOS tube switch circuit. The battery monitoring circuit is connected in parallel to both ends of the battery for monitoring the battery voltage.
