Rokid Air with Wi-Fi adapter and DisplayPort for maximum connectivity. The Rokid Air Pro utilizes the computing power of the smartphone and is simply connected via a DisplayPort cable to the USB-C port. Alternatively, the device can be used through the integrated Rokid Air Wireless Adapter and the screen-cast function of the smartphone. The Rokid Air Pro also draws power from the connected device, so no additional batteries are needed, and the glasses can be used with another smartphone without an extra charging cycle if necessary.
