The USB-C to USB Adapter lets you connect your iOS devices and many of your standard USB accessories to a Mac with a USB-C or Thunderbolt 3 (USB-C) port.
Plug the USB-C end of the adapter into the USB-C or Thunderbolt 3 (USB-C) port on your Mac, then connect your USB flash drive, camera, or any other standard USB device. You can also connect a Lightning to USB cable to sync and charge your iPhone, iPad, or iPod.
