Claude- I've damaged several micro USB jacks in devices with plugs that do not fit exactly as they should. That is far worse than the frustration you and I have with the lightning cables that are simply not compatible from the 5 to the 5S or 6 or 6+. I don't know why Apple had to make two types of lightning cables that look identical yet older ones don't charge the new devices. Too many times I have been traveling and discovered I had the older cable and it would not charge my phone or ipad air 2. Finally I went through and tested all I had and threw them all away that were older. Now the only ones left are those that work on everything.
