Abstract: Provided is a charging system having a circuit for delaying power supply, and more particularly, a charging system having a circuit for delaying power supply installed on a side of a power supply apparatus, wherein the circuit for delaying power supply prevents a spark from being generated when an electronic device and the power supply apparatus are connected to each other. The circuit for delaying power supply blocks the power supply to the Vcc power terminal in the case in which the GND ground power terminal and the D signal terminal are not in an electrically shorted state and releases the blocking of the power supply to the Vcc power terminal because an operation of the transistor is changed and a charging state of the capacitor is changed in the case in which the GND ground power terminal and the D signal terminal become the electrically shorted state.
