Use of Peltier effect for cooling is not new. Various attempts have been made to generate cooling using Peltier effect. Occasionally use of this effect for heating applications is also reported. This paper reports the development and testing of a hot cold tumbler that is capable of heating as well as cooling of a 300cc can of water/tea/coffee or any other liquid. The compact design makes this tumbler portable and can be carried out without any inconvenience. Use of battery makes it possible to use this at remote places or where electric supply is not readily available. The testing showed positive results and tumbler was capable of heating drink can up to 60oC and cooling was achieved up to 20oC within a span of 30 minutes. To reduce this time it was suggested to increase the Peltier chip capacity and solar power to recharge the battery.
