Admittedly, $19 for a charging cable ain't bargain basement but for those like me that were issued a new MacBook and iPhone 8 at work, $19 is worth the convenience of not having to deal with plugging a cable, into a dongle, into your MacBook while traveling.
Apple recently cut the price of the USB-C to Lightning cable from $25 to $19.
What's notable about this cord is that Apple hasn't let any third-party cable makers create authorized versions yet. If you need one, the only manufacturer that sells one that's guaranteed to work is Apple.
This is the cord you need if you want to plug the latest iPhone directly into the latest MacBook without a dongle.
There's one powerful reason to buy this cord, too: It can charge your iPhone X or 8 super-fast — as much as 50% battery in 30 minutes.
If you have a MacBook or similar wattage charger, you can swap the USB-C cord for this Lightning cord, essentially allowing you to charge your phone with your laptop charger.
