Abstract

A portable charger is provided. The portable charging includes a housing and a power source located in the housing so that that the power source can be inductively recharging through the housing. The portable charger also includes a first output connector coupled to the power source for charging a first electronic device, as well as a second output connector coupled to the power source that is different from the first output connector for charging a second electronic device. The first output connector and the second output connector are configured to be at least partially stored within the housing in order to minimize size of the charger.

Claims

1. A portable charger comprising:

a housing;

a power source disposed in the housing inductively recharging therethrough;

a first output connector coupled to the power source; and

a second output connector coupled to the power source that is different from the first output connector.

2. The charger according to claim 1 further comprising a tether connecting the second output connector to the power source, wherein the second output connector is deployable from a stored position.

3. The charger according to claim 2 wherein the housing further comprises a track formed along an outer peripheral surface, wherein in the stored position, the tether and the second output connector are stored in the track.

4. The charger according to claim 1 further comprising an actuator for moving the first output connector between a first retracted position and a second extended position, wherein in the retracted position, the first output connector is retracted at least partially with the housing.

5. The charger according to claim 4 wherein in the retracted position the first output connector is disposed at least partially within the housing and adjacent the power source in in order to minimize the size of the housing.

6. The charger according to claim 3 wherein the actuator further comprises a biasing member that moves the first output connector to an extended position when the actuator is actuated.

7. The charger according to claim 1 wherein the first output connector is adapted to connect to a thirty-pin connector.

8. The charger according to claim 1 wherein the second charging output is adapted to connect to a micro-universal serial bus (USB) connector.

9. The charger according to claim 1 further comprising a charge indicator display in electrical communication with the power source.

10. The charger according to claim 1 wherein the charge indicator further comprises a plurality of light emitting diodes (LEDs).

12. The charger according to claim 10 further comprising an inductive coil and a circuit board in the housing;

wherein at least a portion of the power source, the inductive coil and the circuit board are stacked upon each other thereby overlapping within the housing in order to minimize the size of the housing.

13. The charger according to claim 12 wherein the housing has a length and a width and a height, such that the power source, the inductive coil and the circuit board are stacked in the vertical direction, the first output connector located adjacent the power source, the inductive coil and the circuit board in at least one of the width or length direction in order to minimize the size of the housing.

15. The charger according to claim 10 further comprising a track formed along a peripheral surface of the housing, the second output connector further comprising a tether connecting the second output connector to the power source, wherein the second output connector is deployable with the tether from a stored position, such that in the stored position, the tether and the second output connector are stored in the track.

16. The charger according to claim 10 wherein the housing comprises a pair of shells which are joined to each other to define an opening and a track, wherein the first output connector is moveable through the opening between a retracted position and an extended position, the second output connector adapted to be stored within the track.

17. The charger according to claim 16 further comprising an inductive coil and a circuit board coupled to the power source, wherein the inductive coil is disposed in one of the shells proximate an outer surface through which the inductive coil recharges the power source, the circuit board and power source stacked upon the inductive coil and overlapping within the housing.

18. The charger according to claim 10 wherein the second output connector is different from the first output connector.

19. The charger according to claim 10 further comprising an input connector wherein the power source is rechargeable by an external power source through the input connector.

11. A portable charger comprising:

a housing;

a power source disposed in the housing, the power source being inductively rechargeable therethrough;

a first output connector coupled to the power source; and

a second output connector coupled to the power source,

wherein the first output connector and the second output connector are configured to be at least partially stored within the housing in order to minimize size of the charger.

14. The charger according to claim 11 further comprising an actuator for moving the first output connector between a first retracted position and a second extended position wherein the actuator further comprises a button operable to move the first connector to the extended position through an opening formed along a peripheral surface of the housing when the button is actuated.

20. The portable charger comprising:

a housing formed by a pair of shells joined to each other to define an opening and a track;

an inductive coil disposed in the housing;

a power source coupled to the inductive coil and stacked upon each other thereby overlapping within the housing in order to minimize the size of the housing, the power source being inductively rechargeable therethrough;

a first output connector coupled to the power source adapted for charging a first device, the first output being moveable through the opening between a retracted position and an extended position such that in the retracted position, the first output connector is retracted at least partially within the housing;

an actuator having a biasing member that moves the first output connector to the extended position when the biasing member is actuated; and

a second output connector different from the first output connector adapted for charging a second device, the second output coupled to the power source with a tether, wherein the second output connector is adapted to be stored within the track,

wherein the charger is adapted to charge the first device and the second device without being connected to an external power source.
