Satechi's new Aluminum Clamp Hub provides an iMac with four additional USB 3.0 ports for charging smartphones, syncing and more.

The plug and play Aluminum Clamp Hub attaches to any iMac (2012 or newer) or PC (less than one inch thick) without any installation required. Simply attach the device directly onto the monitor, tighten the screw to attach, and plug in the included USB extension cable.

Additionally, the Aluminum Clamp Hub features a blue LED light to indicate it is powered on and ready for use. The hub is available now for US$27.99 at Satechi.net and Amazon.com.
