Update 05/21/18: Apple has reduced the price of it's 1-meter USB-C lightning cables by $6. We've updated pricing through this article accordingly.
New to this years’ iPhones is fast-charging capability. According to Apple, you can juice up your phone to 50 percent in just 30 minutes! There’s just one catch: You have to buy a new power adapter. Oh, and a new USB-C to Lightning cable, too. That’s two catches, and it's starting to sound expensive.
Is it even worth it? We grabbed five power adapters and three iPhones, ran a bunch of tests, and got to the bottom of the iPhone charging mystery. The truth is, while USB-C fast charging certainly works, you’re much better off buying Apple’s 12W USB-A Power Adapter—the one that comes with most iPads. It’s a lot less expensive ($19) and nearly as fast.
