Modern USB devices are starting to appear with just one USB C port replacing all others, this means you are restricted on what older equipment you can use. The way to get around this and use older equipment is via an adapter. Our USB Type C to Micro B adapter will allow you to use a USB Type Micro B cable on your USB Type C equipment for charging and data transfer. As this adapter is for charging and data transfer it don't matter if your devices are USB C only.
