Drinkware container with active temperature control
An actively heated or cooled mug has a body with a chamber that can receive and hold a beverage and a heating or cooling system disposed at least partially in a cavity below the chamber. The heating or cooling system has a heating or cooling element to actively heat or cool the chamber, power storage devices, and circuitry that controls the operation of the heating or cooling elements. A user interface is electrically connected to the circuitry and has one or more selection members actuatable a) to turn off the one or more heating or cooling element or b) to adjust a temperature setting to one of multiple temperature settings configured to control the one or more heating or cooling elements to heat or maintain the liquid at a user selected temperature.
