Ive having a problem keeping my three devices (iphone, ipad, and MBA) charged. I have two Magsafe chargers, but it means having too many cords, including an extension cards on the floor. Has anyone come across a multi-cord cord charger in which multiple mobile Apple devices can be charged at the same time? I sort of get 5 hours of use out of the MBA but not always, so I have to charge it least once a day. Same goes for the other devices, especially the iphone.
