(All Lightning cables regardless of brand, length, or color are relevant to this article.)
Note that if you are using an iPhone 6 or 6s with the Apple Smart Battery Case, the only way to properly charge both the phone and the battery case at the same time is to use a Lightning to USB cable with an Apple Power Adapter. Connecting a Lightning to USB cable via computer or other peripheral will not charge both devices. Specifically, Apple recommends the following:
1. With the iPhone 6 or 6s in the battery case, plug the Lightning to USB cable that came with your iPhone into the Lightning connector on the case.
2. Plug the other end of the cable into an Apple USB power adapter *, then plug that into a power outlet.
* For the fastest charging, use an Apple 10W or 12W USB power adapter. To charge your iPhone or case as quickly as possible, avoid using processor-intensive apps like games or video editors.
