README
README.mdchrg
chrg is a usbc charging hub. You can use it to charge your devices! It uses a CH224K PD sink as input, and then 4xIP6518 PD source controllers as output.
Thanks to the IP6518, it should support:
- 45W
- USB-C Power Delivery
- BC1.2 charging
- Qualcomm QC2.0 and 3.0 charging
- Apple, Huawei, Samsung, and Spreadtrum fast charging protocols
- I don't have any huawei phones, but maybe you do! You can use chrg to charge them.
Of course, YMMV when plugging in multiple devices. It's mostly bottlenecked by the wattage of your upstream brick (or alternatively 45W as the ip6518 spec says).
Why I made this project
I made this project because I like doing USB projects, and after making a USB data hub, I thought it would be cool to make a charging hub. Plus, this way I can plug in one brick and charge my phone and headphones at the same time. I also think it's cool and was a way to learn a new chip (IP6518).

How to use
Assembly
Print chrg_case.step instead and slide it in from the side, like so:
Then the pins should keep it secure.
Usage
Plug a usbc laptop charger into the side port. Then, charge your devices from the front ports!

Questions
How big is the Chrg PCB?
It measures 96.5 × 31 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Chrg use?
65 parts, built around the CH224K, IP6518, KT-0805G and 0402B102K500NT. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Chrg KiCad files?
From the JBlitzar/chrg repository on GitHub, at the commit this page was made from: the board is PCB/chrg/chrg.kicad_pcb and its schematic PCB/chrg/chrg.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Chrg design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
