I bought an iPad 3 (64GB/4G) recently and was a bit set off by the long time it needed to charge for the first and the second time. The power adapter got rather hot. Then I used the charging device of my "old" iPad 2 and I think it was much faster! The power adapter device looks complete the same as the new charger and all the text (technical data, 10W…) on it is the same (except the model number). Maybe I should have some complete uncharging and full charging cycles first and make another test then. Maybe the new power adapter is defect. Photo of the two devices in the attachment. Mind it's an European model (Austria). Edit: I mixed up the text on the photo. The above is shipped with iPad 3 and the below with iPad 2.
