This charges my iPhone 5S as well as the one that came with my phone, and it costs a lot less than the Apple version. The low price makes it affordable enough to leave a back up charger at work, or just to have one available should the original charger malfunction.
The lightning cables appear to work well and seem well built. I haven't had any issues with any of them. Others I have purchased in the past from other sellers have been cheap and not worked well. These seem to be great so far.
