The Anker Powerline III Flow is one of our favorite third-party USB-C-to-Lightning cables out today. It is incredibly durable, thanks to a silica-gel exterior and an interior with graphene coating. You can order it in black, white, green, grey, and pink.
This version of the Powerline III Flow measures 6 feet in length — more than the bundled iPhone cable. A shorter 3-foot variant of the accessory is also available.
