PowerBank
About the PowerBank PCB
PowerBank is an open source PCB design by sneakylizard123-4, published on GitHub. It is a 4-layer board measuring 50 × 75 mm, with 46 components from 26 distinct parts.
Other key parts include the IP5318. By type, the board carries 14 capacitors, 11 resistors, 10 diodes, 4 connectors, 3 transistors and 1 IC.
From the project
Multi-port USB power bank using the IP5318 fast-charge SoC. USB-C, USB-A, and Micro-USB ports. Built in KiCad 10.

I wanted to make a board using the IP5306's bigger cousin, the IP5318. It is better in many ways, except it is harder to hand solder. It can do DRP USB-C for charging and discharging out of the same connector! It features user-servicable batteries, so they can be replaced instead of replacing the entire power bank
