The magnetic connector is generally a magnet or a ferromagnetic material. The magnetic connector can also be in a ring shape, or a structure of multiple ring arrays can be used as needed. The charging management circuit board is charged directly through the connected charging plug. In particular, in order to ensure stability, the casing can be provided with an arc arm group 470 similar to the interface charger 400, and multiple pairs of arc arm groups 470 are arranged at intervals. It is understandable that the magnetic charger 500 can use the same negative pole 111 as the interface charger 400, or a convex pattern (CD pattern) can be provided as the negative pole.
