Read all instructions before using.

Please take off lid before drinking from the Cosori mug. The opening in the lid is not for drinking from, but for placing a stirring spoon. Do not drink from the lid.

  • Be cautious when drinking. If left on the warmer for too long, the mug may be too hot to drink from immediately (varies based on warmer temperature).
  • Be extremely cautious when moving cups containing hot liquids, to avoid being burned.
  • Do not place stainless steel mug in microwave.
  • Be cautious when heating plate is hot.
  • To prevent electric shock, do not immerse the warmer or AC/DC adapter in water or any other liquid.
  • Do not allow children to play with the warmer. Closely supervise children who are near the warmer.
  • The warmer is not intended for use by persons (including children) with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge, unless they are supervised or given instruction by a person responsible for their safety.
  • Unplug the warmer when not in use.
  • Allow the warmer to completely cool down before cleaning or storing.
  • Do not use the warmer or adapter if they are damaged. Contact Customer Support .
  • Do not cook foods on the warmer. The warmer cannot reach safe cooking temperatures.
  • Do not use the warmer outdoors.
  • Do not place the warmer near gas or electric burners, or in a heated oven.
  • Do not let the cord hang over the edge of a table or counter, or near hot surfaces.

Because the display temperature shows the temperature of the heating plate (not the temperature of the liquid in your cup), set the display temperature higher than the temperature you want for your drink.

  • Example 1: If you set the warmer’s temperature to 230°F, and pour room temperature water (about 89°F) into the stainless steel
    mug, after about 2 hours the temperature of the water will reach up to 156°F (actual time will depend on area temperature and amount of liquid).
  • Example 2: If you set the warmer’s temperature to 230°F, and pour hot coffee into the stainless steel mug, the warmer will keep the coffee’s temperature at 156°F or higher.
