Hello, I have the iPad 4 as well as the iPhone 5 (I realize I'll never have two new products like this ever again, at the same time). I want to know if I can use each charger interchangeably with each product. I know that the iPad lightning charger (box) charges at a higher rating than the iPhone charger. I'm obviously looking for longevity and don't want to cause any undue damage even minimally. DOCUMENTATION FROM APPLE of the ability to do this/or not, from would be greatly appreciated. Thanks in advance! Dean **Update: I chose to take my iPhone chargining square instead of the larger iPad charging square with me. I've had the iPad 4 plugged in for almost an hour and the square portion is getting pretty hot and I can tell that the charging is going at a slower rate than it has with the charging square which was designed for the iPad. Did Apple really need to muddy the waters with making two types of charging boxes for these two devices?!
