Abstract: The invention relates to a portable device (100; 200; 400) for regulating the temperature of an element (1), comprising: an engagement part (2) adapted to be placed in contact with the element (1), a temperature regulation unit (3) comprising a thermoelectric module (4) having two sides (41, 42), a first side (41) of the thermoelectric module being thermally coupled with the engagement part (2). The device (100; 200; 400) further comprises: a reception part (5) adapted to removably receive a phase change material (PCM) (6), a second side (42) of the thermoelectric module being thermally coupled with the reception part (5), such that a phase change material (PCM) (6) provided in the reception part will also be thermally coupled with the second side (42) of the thermoelectric module.
