[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0023] Please refer to Figures 1-3 The utility model provides a kind of mobile power device, including battery part 1 and electronic part 3, the battery part includes first shell and steel shell electric core being arranged in first shell, the electronic part includes second shell, the electronic part is detachably connected with the battery part.

[0024] It can be understood that the detachable connection mode of the electronic part and the battery part includes but is not limited to clamping, plug-in, threaded connection, adhesive and the like.

[0025] For example, in one embodiment, the end of the first shell connected with the electronic part is a connecting end, a first groove is formed around the periphery of the connecting end, i.e. the connecting end and the end of the battery part away from the electronic part form a first step. The connecting end can save the thickness space of the battery part. It can be understood that the outer surface of the connecting end is not limited to be smooth and flat, and the connecting end is not limited to be flush, as long as the electronic part and the battery part can be detachably connected.

[0026] For example, in another embodiment, the end of the electronic part connected with the battery part is a connecting part, a second groove is formed around the periphery of the connecting part, i.e. the connecting part and the end of the electronic part away from the battery part form a second step. The connecting part can save the thickness space of the electronic part. It can be understood that the outer surface of the connecting part is not limited to be smooth and flat, and the connecting part is not limited to be flush, as long as the electronic part and the battery part can be detachably connected.
