Xbox 360 : Plug your pad into the wall

Back in days gone by, when microsft was showing of their Xbox 360 console, there was a charging device that kept poping up during promotion, apparently. The Controller wall charger.
No to be honest I never remember seeing this myself and yet again comes with an Pril the 1st warning, but looks genuine enough.

The kit has now been spotted.
It will allow users to plug the pad straight into the wall and "Fast" charge the battery taking down the charge time to just 2 hours. It has an rrp of $29.99 and will probably end up being £29.99 over hear.
