ABSTRACT:
An intelligent power-supplying device includes an alternating current (AC) input port, a direct current (DC) input port, a displayer, a reset key and a DC output port. The AC input port receives an AC power while the DC input port receives a DC power. The power-supplying device automatically detects the value of voltage or current required by an electronic device connected to the DC output port thereof. The display shows the value of the voltage or current supplied by the power-supplying device. The power-supplying device automatically starts the process of detecting the voltage or current required by the electronic device when the electronic device is connected to the DC output port thereof.
