My S4 will charge using various cables and USB sockets in my car, but it will not charge using a USB outlet I installed on a motorcycle.
I have tried my Galaxy Tab2, a blue tooth ear piece, and even old phones (Samsung Stratosphere, and an older LG Chocolate) using different
cables. All of these charge using this USB outlet on the Motorcycle. What is so unique about the S4 that it will NOT charge using this one
USB outlet when everything else seems to work????
Please help
