This 16-ounce computerized thermal cup ensures that regardless of long commutes, you will always have a warm cup of coffee, soup, or even be able to warm water for tea or heat baby formula while on the road. The mug plugs into your car cigarette lighter and heats your beverage to one of four preset temperatures, (selectable in Centigrade or Fahrenheit), ranging from room temperature (85° F) to very hot (160° F). When the unit is on, the clear digital LCD display shows the content's temperature. A coffee icon will flash on the display to indicate when the beverage is below the preset temperature. When the drink temperature drops 2° F below the set temperature, the heater will turn on to re-warm the beverage. A ready indicator beeps when the desired temperature is again reached, and a warning signal sounds when the temperature reaches above 170° F to protect you from scalding. An easy-grip handle, nonskid rubber base, and safety cap makes the mug safe for travel. The removable inner liner is dishwasher safe. Includes a 12-volt plug and cord. Plastic. Blue. 9" H x 2 1/2" Diam. (1 lb.)
