The power receiving terminal 202 is exposed to the second housing 201 for receiving power. Figure 12 .

[0046] Moreover, the power supply part 100 and the output part 200 are detachably assembled together; the power supply end 104 and the power receiving end 202 are docked with the power supply part and the output part, and are detached with the power supply part and the output part.

[0047] Since the power supply and output parts of the adapter are detachably assembled together, they can be used together or separated as needed to facilitate charging the power supply. The output end of the adapter includes an AC output socket that can output AC power, expanding the scope of use of the adapter.

[0048] Specifically, the first shell 101 and the second shell 201 are separately provided with flanges 105 and slide grooves 204, and the flanges 105 and slide grooves 204 slide against each other to facilitate the disassembly or assembly of the power supply part and the output part, making it easy to assemble or disengage the power supply part and the output part.
