From Apple's Press Release: "...while a new Lightning to USB-C Cable and Apple’s 29W USB-C Power Adapter enable faster charging." Looks like the USB-C charger that's previously been sold as the Macbook charger. Do we know how much faster it will charge? Any third-party USB-C charger that can accomplish the same fast charge if paired with a USB-C to Lightning cable? And could any old USB-A charger accomplish the fast charge if it's high enough wattage?
