Lightning cord will not charge from one side but not in all devices
We bought 2 iPhone 5s about 20 days ago. Also we bought 2 extra genuine lightning cords so we can charge in our Mac as well. Suddenly today two of the cords can charge my phone only from one side, but my wife's iPhone is charging from both sides. The other 2 cords are ok. Also I hade a Mophie helium pack and will not charge.
Any ideas? Everything is bought from an apple store and never got the message that the device will not charge.
Thanks
iPhone 5s, iOS 7.0.4
