Hello Phiatchelt,

Thanks for posting in Apple Support Communities.

"You can charge your iPhone with a USB-C cable and power adapter compliant with the USB-C standard, including USB Power Delivery — such as the cable that comes with your iPhone. These cables and power adapters are widely available from Apple and other manufacturers.

Connect the cable to the USB-C connector on your iPhone and to a compatible USB-C power adapter. Then plug the power adapter into a wall outlet.

If you have a 20W USB-C power adapter or higher-wattage USB-C power adapter — like the one that came with your Mac laptop — you can use it with your iPhone for faster charging. You can also charge your iPhone by connecting it to the USB-C port on your computer."

Best wishes.
