When people travel or explore in the wild, seldom could drink warm water, and it is difficult to heat foods as well. Especially at high altitudes, it is hard to travelers to drink hot boiled water. This design of the travel cup solves the problem effectively. In order to make it easier to boil water, there is a heating system in the travel cup.
