• Your host USB-C port (USB 3.1 is recommended) must support USB™ Power Delivery to ensure full functionality.

  • Your mobile device might require more power than your charger can allow to use the adapter and charge your device simultaneously. To ensure the JCH346 powers and charges your mobile device while in use, a higher wattage power adapter may be required.
