Users are reporting that iPhone 5 lightning cables are sticking into USB ports.
One Apple customer, posting as ‘gvilledh‘, explained his experience:
I went to unplug the USB cable from the wall wart and it was extremely tight. The white sleeve over the connection started to slide off, but I was able to get it out.
gvilledh got his cable replaced by Apple, but says, “My new one is still tight, but not as bad as the first one.”
iGixer explains his negative experience as well:
So I tried to unplug my brand new Lightning connector from the white power block and the white plastic surrounding the USB end slides right of revealing the medal connectors.
“The source of the problem seems to be the two small rectangles cut into one side of the USB A plug, with posters reporting they are a little deeper than those in other connectors. That extra depth seems to result in the tines of a USB socket digging in to a depth at which they won’t easily slide out,” The Register notes.
