[0002] With the advancement of technology and the improvement of people's living standards, the use of mobile devices is becoming more and more common, such as mobile phones, tablet computers, digital cameras, etc. These devices usually need to be charged, so mobile power banks have become an indispensable electronic product in people's daily lives. However, traditional mobile power banks are large in size and inconvenient to carry, and cannot meet users' needs for lightness and portability. At the same time, with the continuous upgrading of mobile devices, higher requirements are also placed on the power reserve and charging speed of mobile power banks.

[0003] Traditional mobile power supplies usually use a single battery cell as a power source, and adjust and control the voltage and current through a circuit board. Although the existing mobile power supply structure is simple, it is large in size and not easy to carry.
