The Kanex USB-C to Lightning Durabraid Cable is Apple MFi Certified, which means that it is  specifically made for Apple products and that you can expect quality performance and reliability. It can deliver high capacity PD (Power Delivery) charging - which is much faster than the 12W that a standard USB to Lightning cable can deliver. This cable is made with DuraBraid™ which is a nylon fiber encasing designed to reduce tangles, increase durability and to offer a unique premium look and feel to your cable. The Kanex USB-C to Lightning Durabraid Cable can be used with a USB-C wall charger to take advantage of your iPhone’s Fast Charging feature which provides optimal voltage based on your battery percentage, improving on effeciency and safety.
