A mobile power supply and smart watch assembly. The mobile power supply comprises a body (2) having a charge input port, and a contact pin (3) matching with a contact (4) of a smart watch (1) and installed on the body, wherein an inner end of the contact pin (3) is connected to a step-up output discharge unit in the body. A matching portion is arranged between the smart watch and the body. The smart watch and the body are detachably fixed via the matching portion, and the contact is arranged to contact the contact pin. The mobile power supply is detachably fixed on the smart watch, and the smart watch is charged via a contact between the contact pin and the contact of the smart watch without including an additional micro-USB port on the smart watch or using a USB cable, thereby charging the smart watch by incorporating the mobile power supply and the smart watch. The mobile power supply addresses the problem in which a USB cable touches, entangles or disturbs an arm of a user when the smart watch is being charged. |
