The UC-E21 is a USB cable manufactured by Nikon. It is designed to be used as a replacement cable for the COOLPIX S6800 digital point and shoot camera and comes in handy when you lose the stock cable that is supplied as part of the camera package. It features a micro type-B male USB connector on one end and a type-A male USB connector on the other. This cable can be used to connect the camera to a computer or a charger. Once connected to a computer, it enables you to easily transfer your photos and videos at high speeds for storage or archival. Apart from the S6800, this cable can also be used with the S5300 digital camera.
