Fast charging gives you a quick and convenient way to recharge your iPhone X, iPhone 8, or iPhone 8 Plus. Your iPhone fast charges up to 50 percent in 30 minutes when you use an Apple USB-C to Lightning cable and one of these adapters:
- Apple 29W, 61W, or 87W USB-C Power Adapter
- A comparable third-party USB-C power adapter that supports USB Power Delivery (USB-PD)
If you're not sure which Apple Power Adapter you have, check the wattage on the bottom of the adapter:
