Hello, About six months ago, I bought the iPad 1. The charger worked really well for several months until I went on a roadtrip to Southern California. I couldn't plug my iPad into the car to charge it so I ended up using the iPhone charger that was already installed in the car. I came back from my roadtrip and all of a sudden my iPad charger does not work well anymore. I have started to use my Grandfather's charger whenever I see him because it works well. When I attempt to use my current charger, I plug it in all night, but I get a message that it is "Not Charging" or something similar, and when I wake up my battery life has only gone up 10-20%. I do not have a PC so I use it as a wall charger. I am not sure what is wrong, is my only solution to buy a new charger?
