The PowerBoost Chargers are super versatile portable power sources. The one missing feature is the ability to pass USB data so you can exchange data with your computer while the LiPo battery is charging. This project turns your PowerBoost Charger into a LiPo Powered USB Data Cable.
The Booster Cable is a relatively easy project. Once you collect all the components and tools, it should only take an hour or two to assemble.
