The magnetic component 163 is fixedly arranged on the side of the energy storage shell 11 close to the functional shell 21. An adsorption component 212 is fixedly arranged on the side of the functional shell 21 close to the energy storage shell 11. In the embodiment of the present application, the adsorption component 212 is selected to be a metal material that can be adsorbed by a magnet. When the energy storage shell 11 and the functional shell 21 are connected, the magnetic component 163 is magnetically fixed to the adsorption component 212, thereby completing the quick connection and fixation between the functional shell 21 and the energy storage shell 11.

[0071] The implementation principle of a modular multifunctional mobile power supply according to an embodiment of the present application is as follows: when a user requires the modular mobile power supply to have different functions in different usage scenarios, the two snap-in blocks 161 are disengaged from the two snap-in slots 211, thereby releasing the fixed connection between the energy storage module 1 and the functional module 2.
