O.K. we all know the possible problems when using 3rd party Lightning cables which are not "approved" or "somehow certified" by Apple. They will mostly charge the iOS hardware, but again mostly will not sync. The "technical reason" be hid these is the so-called authentication chipping that Apple uses. Now I have recently experienced an interesting case: I have two 3rd party, and kind of "no name" cables (say cable #1 & cable #2). I have a iPhone 5, iPad mini (first gen.), iPad4 & finally iPad Air. All are upgraded to the current iOS 7.1.1. Now when I plug cable#1, to any of these iOS devices that usual warning message does appear on the screen(s). But this cable charges the first three devices but NOT iPad Air. It will not sync any of the four. When I plug cable#2, to any of these iOS devices, we're again welcomed with that usual warning message. This cable both charges and syncs the first three devices. It will NOT CHARGE iPad Air, but will SYNC. I use original Apple Charger for these tests (the new 12watt one). Anyone able to provide a sane explanation for the mishap in the case of iPad Air? Thanks.
