CarPlay is handled by your vehicle, not the charger, so it depends on how your car connects.

For wired CarPlay: connect your iPhone directly to your vehicle's USB-A port with a USB-C to USB-A cable, and use the Magnetic Wireless Car Charger as a mount. Connecting the charger itself to the car's data port will not give you CarPlay.

For wireless or Bluetooth CarPlay: pair your phone with the car as usual, then connect the included USB-C to USB-C cable from the mount to a car charger to charge your phone wirelessly while you use CarPlay.
