The JCC154G enables you to output high-definition HDMI 4K video through a USB-C port that supports DisplayPort Alternate Mode. The USB-C display cable gives you the ability to quickly and easily connect your USB-C device to an HDMI TV or display. The additional USB Type-A 5V 1.5A cable allows you to charge a smartphone or tablet when connected to a USB Type-A charger. Due to the 5V power rating, charging for laptops is not supported.
