System Requirements:

• Available USB-C™ port that supports DisplayPort™ Alt Mode and USB™ Power Delivery 2.0 or 3.0.
Please refer to the manufacturer of your hardware for more information on your device

Special Notes:
  • • If you are using high-powered USB™ devices, attach the USB-C® power adapter to the power delivery port to ensure maximum performance. When using your USB-C® power adapter, the multi-adapter powers both the adapter (with attached peripherals) and your laptop
  • • To ensure files copy completely, do not remove the USB-C® power adapter while copying files. For maximum performance, use a computer and USB-C® power adapter equipped with PD 3.0
  • • Your mobile device might require more power than your charger allows when using the adapter and charging your device simultaneously. To ensure the JCA379 powers and charges your mobile device while in use, a higher wattage power adapter may be required.
