The invention discloses a portable computer emergency charging device and a use method. The device comprises an emergency charging module and a locking module. The emergency charging module is arranged in a portable computer through a locking module. The device also comprises an emergency charging module charging device housing and a hand-cranking charging device. The locking module comprises twoguide rails. Guide plates are arranged on the two faces of the charging device shell respectively. A locking shaft penetrates through two fixed blocks, and a moving block and the fixed blocks get close to each other and separate from each other to lift a lifting block. The lower surface of the lifting block make downward contact with the lower surfaces of the guide rails, and the upper surface ofthe guide plates make contact with the upper surface of the guide rails. The hand-cranking charging device is electrically connected with a voltage stabilizing circuit board, and the voltage stabilizing circuit board is electr
