This cable is a USB-A to micro USB-B cable. This cable has extra insulation compared with a standard USB cable making it slightly thicker than normal. The micro USB end is stripped to provide more flexibility when attaching to a device in a case or tight space. Where the extra insulation is in place, the cable is 5mm thick. In the stripped section, the cable is 3.5mm thick.
At 10 feet (3.1 meters) long, this cable gives a bit more reach than many other cables.
