Abstract: The present disclosure provides a flexible thin multi-layered thermoelectric energy generating module in which a unit thermoelectric sheet having an optimized number of contacts and p/n junctions is formed on a single plane, a voltage boosting module using a super capacitor, and a portable thermoelectric charging apparatus using the same. Herein, the unit thermoelectric sheet having an optimized number of contacts has a shape, a thickness, and a width which exhibits best performance at a given temperature difference. To this end, an aspect of the present disclosure includes a thermoelectric energy generating module which converts thermal energy into electric energy; a voltage boosting module which is electrically connected to the thermoelectric energy generating module to boost a voltage of the electric energy; an output unit which is electrically connected to the voltage boosting module to output the electric energy whose voltage is boosted by the voltage boosting module; and a control unit.
