Recently I had an iPad air die and wouldn't turn on which we replaced at Apple.
The next day my iPhone 6S same happens I'm going crazy how must be the charger I check and its one of many AICase cables I've bought from eBay. I stop using it take my iPhone to apple they replace it for me.
I've put it aside to do a bit of research in my office. Busy week ensues.
Fast forward 3 days later my wife's phone is dead and doing the same thing dies wont turn on , she found the cable and used it. lucky under warranty replaced at Apple.
After a bit of research turns out the U2 IC on each was blown caused by the cable. I'm furious i contact the seller and they do nothing and insist it is something else. I throw the cable.
Fast forward another 3 months on my last trip to china I bought a little machine to test cables. My results found that these cables are not MFI certifed at all and in fact use a ridiculously cheap IC inside. The IC inside a 50c cable is what is being used. I've seen a lot of people say they are happy but they charge a bit slow etc etc this is all because it is not certified and is using a really cheap IC inside.
Please see the Imgur album below for whole bunch of different cables. The score is a rating out of 100 for power/data cheap IC will hit under 50 and a high end copy would be 80+
Thanks for posting i actually bought some the other day.
Which seems to charger a little slower than my Belkin cable which is longer.
