If you stop to really think about it, it makes no sense at all to use a separate wall charger, portable charger and USB sync cable with your PC or Mac. All three of those functions are related, and they all involve something with a Lightning plug on one end and a USB plug on the other.
So naturally, Native Union mashed all three functions into a single smart device: Check out the Native Union JUMP Cable for Apple Lightning Devices, an Apple MFi Certified device that pulls triple duty.
