[0025] Example 1

[0026] A multi-interface PD power supply, such as Figure 1-4 As shown, it includes a protective shell 1, the inner wall of which is provided with a lithium battery block, the outer wall of the protective shell 1 is provided with an L-shaped card slot 14, the inner wall of the L-shaped card slot 14 is provided with a plurality of charging interfaces 19, the inner wall of the L-shaped card slot 14 is rotatably connected with a connecting rod 11, the outer wall of the connecting rod 11 is fixed with a baffle 2, the outer wall of the protective shell 1 is provided with a group of slots 4, the inner wall of the slots 4 is provided with a socket 13, a clamping head 3 is fixed to the outer wall of one side of the baffle 2, and the clamping head 3 is plugged into the inner wall of the socket 13; a sealing ring 20 is fixed to the inner wall of the L-shaped card slot 14, and a sealing gasket 21 is provided on the outer wall of one side of the baffle 2.

[0027] The user can charge the mobile device through the multiple charging interfaces 19 set on the inner wall of the L-shaped card slot 14, and replenish the power of the lithium battery block inside the protective shell 1. When the user does not use the PD power supply, the baffle 2 can be rotated to the side of the charging interface 19 through the connecting rod 11, and then the card head 3 is buckled into the socket 13 on the inner wall of the slot 4, so that the charging interface 19 inside the L-shaped card slot 14 is shielded and protected by the baffle 2.
