Abstract

A multi-source power adapter includes multiple adapter interfaces for connecting the charger unit or another electronic device to a power source, such as a standard power outlet, a car charger port, an airplane charger port, or a USB interface. In a preferred embodiment, the multi-source adapter unit provides an all-in-one charger adapter in a compact, lightweight unit. The charger adapter includes a body enclosing electrical connections; a wall plug interface operatively connected in the body and configured for insertion into a wall socket; a car charger interface formed on the body and configured for connection into a car socket; and a power output port formed in the body, and connected with the wall plug interface and with the car charger interface via the electrical connections enclosed in the body.

Claims

1. A multi-source power adapter comprising:

a body enclosing electrical connections;

a wall plug interface operatively connected to the body and configured for insertion into a wall socket;

a car charger interface formed on the body and configured for connection into a car charger socket, wherein the car charger interface is removably attached to the body;

an airplane charger interface formed on the body extending outwardly from one end of the body and configured for connection into an airplane charger socket, wherein the airplane charger interface is disposed within the car charger interface when the car charger interface is attached to the body and such that removal of the car charger interface from the body exposes the airplane charger interface for use; and

a power output port formed in the body, and connected with the wall plug interface, the car charger interface and with the airplane charger interface via the electrical connections enclosed in the body.

2. The multi-source power adapter as claimed in claim 1, wherein the wall plug interface is pivotally connected to the body and is movable between a storage position and a use position.

3. The multi-source power adapter as claimed in claim 1, further comprising at least one connector cable having a first end configured for engagement with the power output port and having a second end configured for engagement with an electronic device for supplying power to said electronic device when one of the wall plug interface the car charger interface and the airplane charger interface is connected with an external power source.

4. The multi-source power adapter as claimed in claim 1, further comprising at least one indicator light provided on the body, said indicator light being operatively connected with the electrical connections housed in the body for indicating when power is applied to one of the wall plug interface the car charger interface or the airplane charger interface from an external power source.

5. The multi-source power adapter as claimed in claim 1, further comprising a battery associated with the electrical connections for supplying electrical current to the power output port and for receiving electrical current from the wall plug interface from the car charger interface or from the airplane charger interface.

6. The multi-source power adapter as claimed in claim 5, further comprising a switch associated with the battery for causing the battery to supply electrical current to the power output port in response to an actuating motion of the body.

7. A multi-source power adapter comprising:

a body enclosing electrical connections;

a wall plug interface operatively connected to the body and configured for insertion into a wall socket;

a car charger interface formed on the body and configured for connection into a car charger socket;

an airplane charger interface formed on the body extending outwardly from one end of the body and configured for connection into an airplane charger socket;

a power output port formed in the body and connected with the wall plug interface, the car charger interface and the airplane charger interface via the electrical connections enclosed in the body; and

at least one connector cable having a first end connecting interface configured for engagement with the power output port and having a second end comprising additional connection interface electrically connected with the connection interface of the first end and configured for engagement with an electronic device for supplying power to said electronic device when one of the wall plug interface, the car charger interface and the airplane charger interface is connected with an external power source.

8. A multi-source power adapter comprising:

a body enclosing electrical connections;

a wall plug interface operatively connected to the body;

a car charger interface formed on the body;

an airplane charger interface formed on the body extending outwardly from one end of the body; and

a power output port formed in the body, and connected with the wall plug interface, the car charger interface and the airplane charger interface via the electrical connections enclosed in the body;

wherein the car charger interface is removably attached to the body, and wherein the airplane charger interface is disposed within the car charger interface when the car charger interface is attached to the body and such that removal of the car charger interface from the body exposes the airplane charger interface for use.

9. The multi-source power adapter as claimed in claim 8, wherein the wall plug interface is pivotally connected to the body and is movable between a storage position and a use position.

10. The multi-source power adapter as claimed in claim 8, further comprising at least one connector cable having a first end configured for engagement with the power output port and having a second end configured for engagement with an electronic device for supplying power to said electronic device when one of the wall plug interface, the car charger interface and the airplane charger interface is connected with an external power source.

11. A multi-source power adapter comprising:

a body enclosing electrical connections;

a wall plug interface operatively connected to the body;

a car charger interface formed on the body;

an airplane charger interface formed on the body extending outwardly from one end of the body wherein power is supplied to the power output port when the airplane charger interface is connected with an airplane charger socket;

a power output port formed in the body, and connected with the wall plug interface and with the car charger interface via the electrical connections enclosed in the body; and

a squid connector cable having a first end comprising a connection interface configured for engagement with the power output port of the body, and having a second end comprising additional connection interfaces electrically connected with the connection interface of the first end and configured for engagement with respective electronic devices to supply power to said electronic devices when one of the wall plug interface and the car charger interface is connected with an external power source;

wherein the car charger interface is removably attached to the body, and wherein the airplane charger interface is disposed within the car charger interface when the car charger interface is attached to the body and such that removal of the car charger interface from the body exposes the airplane charger interface for use.

12. The multi-source power adapter as claimed in claim 11, wherein the wall plug interface is pivotally connected to the body and is movable between a storage position and a use position.

13. The multi-source power adapter as claimed in claim 11, wherein the squid connector cable further comprises a retractor connected between the first end and the second end for adjusting the length of the cable.

14. The multi-source power adapter as claimed in claim 11, further comprising a power indicator means in the squid connector cable to indicate the flow of an electrical current to the additional connection interfaces.
