The coffee machine in the cafe has been heating up, and the radiator in the home has been heating up... eventually leading to excess heat, unconsciously, heat loss. Why don't we make full use of this heat?
The heater in this design is to fully absorb the excess heat from the heat source, store it, and convert the heat into electrical energy. When we need it, we can release electricity to heat our drinks and provide a little warmth for our cold winter.

Turn on the charging mode, contact the heater with the heating source (coffee machine warm cup area, home radiator, etc.), the metal heat absorption disk at the bottom of the heater absorbs the excess heat energy of the heating source, stores the heat and converts it into electric energy

In winter, the heat stored by the heater can be released through the converter. During work and leisure, our coffee and health tea are heated and kept warm. The whole process is green and environmentally friendly, making full use of the excess heat in cafes and families to bring a little warmth to our lives.
