Gradient is an ultra-portable electrically powered concept device that will maintain a steady temperature of a cup of tea or coffee. This lightweight device offers easy operating with the buttons placed on the case and you can monitor the temperature on the highlighted LED display. The lower surface of this device is actually a heating shell that can keep the cup warm and when it comes about keeping your beverages chill, the upper impeller acts. When the gadget is set to warm a cup, the LED light turns red and when it is in chilling mode, the LED light turns blue.
