My sister and I have been sharing a 4th generation iPad the past few weeks, she'll have it one week, I will the next. We purchased a second lightning cable so that we wouldn't have to worry about charging it at each others houses. When she brought it over last night, she grabbed the 12w wall charger, and the cable that came with the iPad. She commented that the cable was getting very hot, and after she left I plugged the iPad back in. Using the apple charger, as well as a 2.1 amp wall adapter I use for my phone, the iPad wouldn't charge. Plugging it into my iMac would cause the "Too much power" warning to pop up instantly, and the PS3 couldn't charge it either. I took the iPad to a friend's house, and using their lightning cable allowed me to charge the iPad a little bit. I stopped at the closest apple store and showed my cable to two employees. They gave me a new cable. I'm curious if anyone else has run into an issue where the cable has gotten so hot, that the connector casing looked warped afterwards. I should've snapped a picture of it before taking it in, but I wasn't thinking ahead.
