The way I made my hack is I took a old USB camera cable and cut off the non-usb end. Stripped the red a black wires. Because the other wires are the data cables. Then I cut off the car adapter end of charger and stripped those cables. Soldered them up and wrapped them in duct tape. Now I can charge my phone with my new Mac Mini without having to plug my phone into the wall!
PROBLEMS: The mini reconizes it as a USB hub. I just think it is a small, ignorable issue.
I will post photos later today!
