Summarythis is an adapter i made for my Uniden radio. my battery is not charging any more so this is my solution instead of getting a new one. the usb cable is connected to the car lighter and powers the device. all i had left to do is drill a hole on the back cover and put the cable throw it so it will be closed. to make one you will need the printed part , 2 m4X10 screws and usb cable. cut the end of the cable and split the wires, wrap each one on the right screw and tighten it. pay attention! the original battery is 4.8v 700mA while most of usb transformers are 5 v and 1000mA,
