Description

Technical Field

[0001] The utility model relates to the technical field of solid-state battery power bank cells, in particular to a mobile solid-state battery power bank cell. Background Art

[0002] A power bank generally refers to a mobile power source, which is a portable charger that an individual can carry with him or her, can store electrical energy, and is mainly used to charge handheld mobile devices and other consumer electronic products (such as wireless phones and laptops).

[0003] The power bank in the prior art includes a housing, a PCB circuit board, and a battery cell (ie, a battery), wherein the PCB circuit board and the battery cell are arranged in the housing for use.

[0004] However, in actual use, the shell and battery cell packaging technology adopt a sealed structure, which is inconvenient to disassemble and assemble. When the internal battery cell components are damaged or the battery cell capacity decreases, the entire power bank can only be replaced, which easily causes a waste of resources;

[0005] At the same time, since the power bank is used as an emergency power source, a charging cable is often required when charging most consumer electronic products. Most of the existing power banks do not take this into consideration when designing and using them. The charging cable, as a necessity when using, is difficult to store with the power bank. Once forgotten, the power bank will become unusable. Utility Model Content
