I currently am using a cord on my wireless controller to charge up the battery, and I would love to have the new Quick Charge kit that is finally out for $29.99 USD.
Joystiq had a 30 second review on it not too long ago which included words like: fast, sexy, better, and easy.
Will I grab one of them? Maybe when I get a second controller or something, and have a need to charge the batteries back up in around two hours.
