ElevationHub is a hub for MacBook introduced by Elevation Lab. Although it is only a pocket size, it has various functions that take advantage of USB Type C. It is a hub that plugs into the Type C terminal of Apple’s official USB Type C power adapter, and has an SD card slot on the side of the hub, a USB Type A terminal on the back, and a type C terminal for charging. It allows you to add an SD card and USB port simply by snapping it between the adapter and the cable.
