I thought I had a problem with the Lightning port on my phone. It charged intermittently and not at all after I cleaned it. It turns out it was the cheap brand X (for that infamous big internet sales company) cable. The new Anker cable makes my phone charge again. No need for a repair or a new phone, just a new cable.
I am very satisfied with this cable and I have bought multiple and use them to charge my phones everywhere. These last ALOT longer than the stock apple cable and are worth the money.
