Apple MFi means that this cable is 100 percent compatible with your Apple iOS devices with Lightning connector. This USB-C to Lightning cable allows you to rapidly charge with up to 18 watts of Power Delivery (PD) using a compatible USB-C PD charger. The flat cable design resists tangling, saving you the time and frustration. Superior internal structural design is capped by aluminum connector heads, resulting in a cable that is much more durable.
