When needed, the guide block 14 can be enabled to have the function of power output through the switch.

[0027] A wireless charging pad 2 is sleeved on the outside of the mobile charging source 1. The position where the wireless charging pad 2 connects to the guide block 14 is set to be a wireless adsorption conductive pad 22. The setting of the wireless adsorption conductive pad 22 can provide an adsorption force for connecting the wireless charging pad 2 and the mobile charging source 1, and at the same time complete the electrical connection between the mobile charging source 1 and the wireless charging pad 2.

[0028] The bottom end of the wireless adsorption conductive pad 22 is folded and connected to the wireless base pad 21, the inner wall of the wireless base pad 21 is electrically connected to the charging transmitter blocks 211 arranged equidistantly, and the edge of the charging transmitter block 211 is connected to the remote wireless block 212.

Then, the device to be charged can be placed on the outside of the wireless base pad 21, and the charging transmitter block 211 can be used for charging.

[0038] If the device needs to be supported for operation and viewing, the wireless top pad 24 can be opened, and the vertical pad 241 connected to one end of the wireless top pad 24 can be folded. Then the device can be attached to the surface of the vertical pad 241, and the magnetic sheet 243 can be used to adsorb and fit the bracket charging adsorption sheet 242 to the device to complete the charging of the device. At the same time, when the magnetic sheet 243 is adsorbed, the device can be moved. As the device moves, the bracket charging adsorption sheet 242 will rotate, so that the device can be placed at various angles. After moving, the magnetic sheet 243 will fit with the device to form a support to maintain the placement stability of the device.
