Abstract: The present invention discloses a charger for charging a mobile terminal, where the charger and the mobile terminal both have a Type-c port, the charger identifies the type of the mobile terminal, and is configured as Power Delivery charging mode or user-defined charging mode according to the identification result.

Abstract: The present disclosure provides a mobile terminal and a heat sink thereof. The heat sink includes a first heat-conducting medium filled in a gap between a processor and a processor shield, a second heat-conducting medium filled in a gap between an electronic component and an electronic component shield and a third heat-conducting medium filled in a gap between the electronic component shield and a middle frame; the processor is disposed on one side, facing towards a rear casing, of a printed circuit board; heat dissipated from the processor is dissipated by a first heat dissipating channel composed of the first heat-conducting medium, the processor shield and the rear casing; heat dissipated from the processor is dissipated by a second heat dissipating channel composed of the printed circuit board, the second heat-conducting medium, the electronic component shield, the third heat-conducting medium and the middle metal frame.
