Magic Hub
The Magic Hub is a fully powered USB hub for the Apple iMac or Cinema Display, but it’s missing one significant thing found on most powered hubs; a power cable. That’s because it mounts to the back of your iMac/Cinema Display and uses the built-in power port. It adds four USB 3.0 ports and can charge your devices even when the iMac or display is turned off.

You can pre-order the Magic Hub for $49.90 now, with shipping set to begin on October 1st.
