Abstract

A power supply apparatus mainly includes a main body which holds all related elements. The main body has a power supply input end, at least two power supply output ends, a regulation means corresponding to each of the power supply output ends and a power conversion circuit located in the main body. The power supply input end is connected to city power to receive AC power which is transformed by the power conversion circuit to a power supply mode preset by the regulation means. The transformed power supply is transmitted to each of the power supply output ends to be delivered to an electronic device connecting to each of the power supply output ends.

Claims

1. A power supply apparatus, comprising at least:

a main body for holding all related elements;

at least one power supply input end to receive input of a power supply and transmit the power supply to a power conversion circuit;

the power conversion circuit located in the main body to transform the input power supply to a required power supply mode and deliver to power supply output ends;

at least two power supply output ends connectable to selected electronic devices to output the power supply to the corresponding electronic devices; and

a regulation means corresponding to each of the power supply output ends to adjust output power supply mode of the power supply output ends.

2. The power supply apparatus of claim 1, wherein the power supply input end is connected to a city power to receive AC power to the power conversion circuit.

3. The power supply apparatus of claim 1, wherein the power conversion circuit transforms AC power to DC power.

4. The power supply apparatus of claim 1, wherein each of the power supply output ends includes a second power cord and a DC connector.

5. The power supply apparatus of claim 1, wherein the power supply input end includes a first power cord, a socket and a plug.

6. The power supply apparatus of claim 5, wherein the socket includes an insulation case which has a circular assembly trough, at least one notch on one side of the assembly trough, and an arched slot between the notch, the assembly trough further having a contact reed to be coupled with the plug and a push element close to the assembly trough that is extended outside the surface of the notch in normal conditions, the plug including an insulation coupling portion, pins located on the coupling portion and a pad beneath the coupling portion, the coupling portion further having a flange on the bottom insertable into the notch and another notch on one side to receive the push element, the pad having an aperture corresponding to the plug to receive the contact reed.

7. The power supply apparatus of claim 4, wherein the second power cord is stored in the main body through a wire collector, the main body having an opening to allow the second power cord to be pulled out.

8. The power supply apparatus of claim 1, wherein the regulation means is a rotary knob.

9. The power supply apparatus of claim 1, wherein the regulation means regulates voltage values of the power supply output from the power supply output ends.
