This OTG cable has a USB Type-C male plug on one end and a USB-A female port on the other, joined by a short black lead. Plugged into a phone, tablet or laptop with a USB-C port, it lets you connect USB-A accessories such as a flash drive, wired mouse, keyboard or game controller. The blue USB-A port in the photo carries a SuperSpeed marking. The host device must support OTG for the accessory to work. This is a new accessory.
