Ipad 4 have a massage "not charging"
I have an ipad charger for 4th generation. When I connect it to the ipad so that it can charge it charges correctly for a bit but then it tells me that it is not charging
Have you tried to give your iPad a reset? Hold down the sleep and home keys until you see the silver apple. Let it reboot and try again.
You may also want to try a different charger. See if you can replicate teh issue. If you can, then there's something going on with your iPad, if you can't then it's probably the charger.
