The “Super Dock” is a dock for my moto x (2014) phone that has a giant 4200mAh battery in it. It keeps my phone charged for a few days instead of just 10-12 hours.
I made the dock several months ago. It consists of 2 parts. The first part is the actual dock. It’s molded so that the moto x just snaps into it. It has a USB plug at the bottom to charge the phone.
The second part is the cover. It is molded to fit around the dock and protect the battery and circuit. It fits snugly on the dock part and the bottom of the phone.
