A fishing lure power charging device includes a body. A circuit board is assembled in the body. The circuit board has a power switching circuit and a charging circuit. A light emitter is assembled in the body and electrically connected to the power switching circuit, so that the light emitter emits light when the light emitter is electrically conducted. A battery is assembled in the body and electrically connected to the charging circuit, so that the battery is chargeable. Two conductive members are electrically connected to the circuit board, separately assembled to the body, and exposed from the body. A light sensing switch is assembled to the body and electrically connected to the circuit board, so that the light sensing switch switches the two conductive members to conduct with the power switching circuit or the charging circuit based on the light illuminating on the light sensing switch.
