The size is very small, control of charging is very accurate and it can fully charge your devices.

I have created this project online using Inventhub, the git bash version control gives the user the facility of uploading schematic, PCB diagrams there with an easy way of managing and hosting users' libraries. I can also collaborate with others to get responses and feedback on my project. I have created BOM and releases of my project so that I will be able to send it to the manufacturer to get fabricated PCB and components.
