A DC power spraying tool includes a housing (10) having an inlet opening (11), a discharging opening (12), and a motor cavity (13), a liquid container (20) for containing a liquid colorant therein communicatively connected to the inlet opening of the housing, a spray nozzle (30) extended from the discharging opening (12) of the housing to communicate with the liquid container, and an electric motor supported within the motor cavity of the housing for applying a vacuum pressure on the liquid container to pump the colorant towards the spray nozzle. A DC power source (50) includes a rechargeable battery (51) supported by the housing (10) for applying a DC current and a control circuitry (52) electrically connected the rechargeable battery (51) with the electric motor (40) for transforming the DC current to an impulse current so as to drive the electric motor to operate. <IMAGE>
