Description

Portable charger Technical Field The utility model relates to the technical field of portable chargers, in particular to a portable charger. Background The battery with the multi-layer stacked structure is a battery system formed by connecting a plurality of single batteries in series, is commonly used for hydrogen energy power generation and energy storage application, the single batteries comprise bipolar plates and membrane electrode assemblies, the single batteries are stacked together through electric connection so as to transmit electric energy among battery units, and the multi-layer stack can effectively increase the power output of the battery. The battery with the multilayer stacked structure needs strict tightness to prevent hydrogen leakage, the alignment of the battery shell and the cover shell is not rapid enough and the installation is not firm, the sealing ring is possibly not completely butted, gaps can occur in the contact between the shell and the cover shell, the battery performance is reduced, the power output is unstable, the battery with the multilayer stacked structure is used for making the battery charger with the inner core, the power is high, the stability is high, the output is higher, and the multilayer stacked structure is used for making the inner core, so that the portable battery charger is designed. Disclosure of utility model The utility model aims to provide a portable charger, which solves the problems that a gap may occur in contact between a battery shell and a cover shell with a multilayer stacked structure, which are proposed in the background art, so that the battery performance is reduced and the power output is unstable. In order to achieve the purpose, the portable charger comprises a shell and a cover shell, wherein the cover shell is arranged on one side of the shell, a multi-layer electric pile is arranged in the shell and comprises a plurality of bipolar plates and a plurality of membrane electrode assemblies, a first reinforcing plate is arranged at the top of the shell, two reinforcing plates are arranged on one side of the first reinforcing plate, side plates are fixedly arranged on two sides of the first reinforcing plate, stability enhancing plates are fixedly arranged on one sides of the two side plates, and convex plates are fixedly arranged on two sides of the cover shell. As a preferable technical scheme of the utility model, two mounting blocks are fixedly mounted on two sides of the shell, and the positions of the two adjacent mounting blocks are corresponding. As a preferable technical scheme of the utility model, two second magnet strips are arranged on one side of each convex plate, and two first magnet strips are arranged on one side of each stability augmentation plate. As a preferred embodiment of the present utility model, the four second magnet bars are magnetically connected to the four first magnet bars, respectively.
