The lightning cable by Apple is used to charge the iPhone 5, 5s, 6, 6s, 6Plus, 7, etc. This cable comes as the charger in the box with the iPhones. This charger is very small, but very sturdy. I have never had an issue with it not working. The cord is 3 feet long, and very durable - especially compared to the iPhone 4s cable. I purchased my extra cable from Walmart for $24
