PowerBox is my custom-designed PCB that handles USB-C Power Delivery input, dual-cell lithium battery management, balance charging, and regulated power output, all in a single compact board. Designed to push up to 36W of power to whatever you throw at it.

PowerBox was built to power DIY cyberdecks and portable computing projects that need more juice than a standard battery banks can provide.
