Technical Field
[0001] This utility model relates to the field of mobile power supply technology, and in particular to a mobile power supply. Background Technology
[0002] A portable power bank is a hybrid of a charger and a backup battery. In some outdoor scenarios, portable power banks are often needed as a power source.
[0003] A portable power bank typically consists of a housing and a module housed within it. This module typically comprises several battery modules, an inverter module, and other components. For stability, the battery modules are typically secured to the housing using injection molding and screws. This installation method is relatively cumbersome. Alternatively, individually securing each battery module with screws would require additional assembly steps, leading to tedious disassembly and reassembly and increasing the production cost of the portable power bank.
