Connecting iOS devices and numerous standard USB accessories to your Mac, iPad, or iPhone that has a USB-C or Thunderbolt 3 (USB-C) port is made possible by the USB-C to USB Adapter. Connect a flash drive, camera, or other common USB device after inserting the USB-C end of the adapter into the Thunderbolt 3 (USB-C) or USB-C port on your Mac, iPad, or iPhone. To sync and charge your iPhone, iPad, or iPod, you can also use a Lightning to USB cable.
