Power interface, mobile terminal and power adapter

A mobile terminal, comprising a power interface, the power interface comprising:

• a body portion adapted to be connected with a circuit board;
• multiple data pins spaced from one another, the data pins being connected with the body portion;
• and
• multiple power pins spaced from one another,
• the power pins being connected with the body portion, the power pins being spaced from the data pins, each power pin comprising two first contact surfaces and at least one second contact surface adapted to be wrapped with an insulating coating portion and extending perpendicular to the first contact surfaces, the two first contact surfaces being positioned on two opposite sidewalls of the power pin, one of the two first contact surfaces being adapted to be electrically connected with one conductive member of a power adapter, the other one of the two first contact surfaces being adapted to be electrically connected with another one conductive member of the power adapter different from said one conductive member,
• at least one protrusion being arranged on the second contact surface to increase a current load capacity of the power pin.
