Abstract

A power adapter includes a housing, a power input portion and a connecting wire. The housing has a reel device mounted therein, and a wire outlet and more than one output portions formed in one side wall. The power input portion is mounted on the housing. A first end of the connecting wire is extended into the housing through the wire outlet and connected with the reel device thereby the connecting wire can be retracted via the reel device, and a second end thereof is connected with an electrical connector which extends out of the wire outlet. Basing on the structure, the connecting wire can be pulled out of the power adapter for use or retracted in the power adapter for collection via the reel device.

Claims

1. A power adapter, comprising:

a housing, having a reel device mounted therein, a wire outlet formed within a receiving groove formed in an opening in the housing, and a plurality of output portions formed in one side wall thereof, wherein at least one of the plurality of output portions is a cigarette lighter socket;

a power input portion mounted on the housing, wherein the power input portion is an independently detachable power cord, a first end of the power cord having a joint mounted thereon and a second end thereof connectable to one side wall of the housing;

wherein the housing has a stationary first power connector, distinct from, and mounted on one side wall thereof and the power cord has a second power connector mounted on the second end thereof, the second power connector removably engaging with the first power connector; and

a connecting wire, a first end of the connecting wire extended into the housing through the wire outlet and connected with the reel device, wherein the connecting wire is retractably engaged with the reel device, and a second end thereof connected with an exchangeable connector for connection with an electrical connector, the exchangeable connector being received within the receiving groove and being extendable from within the housing.

2. The power adapter as claimed in claim 1, wherein the reel device is a reel.

3. The power adapter as claimed in claim 1, wherein the output portions are USB ports.

4. The power adapter as claimed in claim 1, wherein the output portions are AC output sockets.

5. The power adapter as claimed in claim 1, wherein the joint is a cigarette lighter plug.

6. The power adapter as claimed in claim 1, wherein the joint is a power plug and a transformer is disposed on a middle portion of the power cord.

7. The power adapter as claimed in claim 1, wherein the connecting wire is a flat ribbon cable.

8. The power adapter as claimed in claim 1, wherein the exchangeable connector has a first connecting portion and the electrical connector has a second connecting portion engaging with the first connecting portion.

9. The power adapter as claimed in claim 1, wherein the electrical connector is a Mini-USB connector.

10. The power adapter as claimed in claim 1, wherein the electrical connector is a USB connector.

11. The power adapter as claimed in claim 1, wherein the electrical connector is a power connector.

12. The power adapter as claimed in claim 1, wherein the electrical connector is a FireWire connector.
