got an ipad air, only charges through the adaptor, nothing else. anyone has the same question?
My iPad Air charged from a USB port on my computer, a USB port in my wall outlet and from and Anker portable battery.
Are you using a certified lightning to USB cable? Be sure to use a good cable. Try with the cable that came with the iPad if you are using different cables.
First thing to try is to reset your device. Press and hold the Home and Sleep buttons simultaneously until the Apple logo appears. Let go of the buttons and let the device restart. See if that fixes your problem.
