I have a bad USB to Micro USB cord on my stock Barrel power supply. I know it's the cord too cause I have two chargers and the good cord works with either barrel. My question is can I use USB to Micro USB cord from a camera on my TP? In other words, are the power pins the same. In even more words is a USB to Micro USB cord the same on the power pins no matter what it is used for?? The cam cord is very good quality and appears to be same or better gauge wire.
