When I bought my ipad I also got an iphone. I thought all the stuff was interchangeable. For the most part I was right. The only thing not being the same is the wall charger and I would assume the car charger. Here's my problem. I had the iphone and all it's accessories mixed in with the ipad ones. So when it came to the charger I don't know if the one I have is the iphone one or the one for the ipad. Oh also to make this more confusing one of the wall chargers vanished. The one I have says 10w and when I plug it in to the ipad it gets insanely hot. I left it in there for over an hour and I thought it was going to blow up. My question is am I using the iphone one. Or is the iphone adapter 5w?
