This is the most extensive version of the PowerCube. It has a 5ft. extension cord fitted to it, so it can be mounted to have a power outlet within reach. To do this, a stick-on dock is included. An ideal location is your desktop: there is no more need to duck beneath your desk to plug in your laptop! Besides the extension cord, also a Dual USB port is included, so your mobile devices can be recharged from your desktop.
