Purpose of production:
1. I bought a transparent power bank from PDD, and found that the capacity is not only small, but also generates a lot of heat, and half of the components are on the back of the motherboard and cannot be seen on the surface, so...

Hardware description:
1. Due to the rapid popularity of TYPE-C interface, many fast charging tend to be TYPE-C interface, so the ACC interface is used Design
2. Use a large 1770 inductor to increase the current load capacity and enhance heat dissipation
. 3. Since I am relatively primitive, I think LED lights look better than digital tubes, so...
4. All components are designed on the front to facilitate personal welding.
5. The design follows the principle of good-looking, and I try my best to lay it out as much as I can (some places are not carefully laid out, welcome to debug)
