How to Fast Charge the iPhone XR and XS (And What You'll Need)
The good news is you don’t need a wireless charger to take advantage of the new feature. The bad news: You will have to shell out some cash for a cable and power adapter. The accessories that come included with all iPhones are only capable of regular old slow charging. You deserve better.
Why Apple doesn’t supply the Lightning to USB-C cable and USB-C power adapter you need is a question for another day (but really, why?!). All you need to know is that Apple sells both of these products for an additional cost.
A short Lightning to USB-C cable (opens in new tab) starts at $25. Apple also makes the 29W USB-C power adapter (opens in new tab) you can use to fast charge your iPhone for $49. If you own a new MacBook Pro, you might already have one of these on hand. You can also use a third-party version, as long as it supports USB Power Delivery.
When the iPhone 8 came out last year, we tested third-party fast chargers and found that the ZMLM USB Type-C Wall Charger (opens in new tab) charged that phone about as fast as Apple’s own power adapter, but for half the cost. Unfortunately, as of this writing, that charger no longer appears to be in stock at Amazon, though other options remain available.
You don’t need to do anything special to set up fast charging. Once you have the necessary cable and charger, your new iPhone will automatically charge more quickly.
