PowerBank

PowerBank

Multi-port USB power bank using the IP5318 fast-charge SoC. USB-C, USB-A, and Micro-USB ports. Built in KiCad 10.

Why I Made This

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
