Abstract

A portable charger is provided for charging electronic devices from a rechargeable internal battery. To accommodate multiple electronic devices, a portable charger unit is combined with multiple power output connection interfaces for connecting to more than one electronic device, as necessary, including connector cables attached to the charger housing or power connection ports. The charger also includes at least one power input connection interface for recharging the internal battery from an external power source, including an AC wall plug interface and a DC car charger interface, each connected to the charger housing and movable between a retracted, storage position and an extended use position. The power output connector cables can also be stored within storage cavities formed in the charger housing when not in use and extended therefrom for connection with electronic devices in need of recharging. The power connection ports can act as power inputs, power outputs, or both.

First claim

What is claimed is:

1. A portable charger unit for recharging at least one electronic device having a rechargeable internal battery, said portable charger unit comprising:
a charger housing internally storing a rechargeable battery;
a wall plug input connection interface connected to the charger housing for movement between an extended position where said wall plug input connection interface extends away from the charger housing for use and a retracted position for storage of said wall plug input connection interface within the charger housing, said wall plug input connection interface being operatively connected to the internal battery for providing an electrical charge from an external wall socket power source to the charger unit when said wall plug input connection interface is operatively engaged with said power source and for recharging the internal battery when the charger unit is connected to said power source in said manner;
a car charger input connection interface connected to the charger housing for movement between an extended position where said car charger input connection interface extends away from the charger housing for use and a retracted position for storage within the charger housing, said car charger input connection interface being operatively connected to the internal battery for providing an electrical charge from an external car charger socket to the charger unit when said car charger input connection interface is operatively engaged with said external car charger socket and for recharging the internal battery when the charger unit is connected to said car charger socket in said manner,
wherein both the wall plug interface and the car charger interface are pivotable to respective retracted positions and disposed within the general footprint of the charger housing when in said retracted positions, and
at least one power connection output connector cable operatively connected to the internal battery for providing an electrical charge from the internal battery to an electronic device when said device is connected to the charger unit via the power connection output connector cable, said connector cable comprising:
a proximal end attached to the charger housing,
a distal end having an output connection interface adapted for engagement with an electronic device; and
an intermediate portion extending between said proximal and distal ends of said connector cable,

wherein at least the output connection interface of said power connection output connector cable is storable within a storage cavity formed in the charger housing so that said output connection interface is contained within the general footprint of the charger housing when not in use and is removable from said cavity to an extended position for use to connect with an electronic device.

2. The portable charger unit according to claim 1 , wherein the car charger interface comprises:
a proximal end attached to the charger housing;
a distal end having a head portion including the interface adaptable for engagement with the car charger socket; and
an intermediate cord portion extending between said proximal and distal ends, wherein the charger housing includes a cavity for storage of the head portion when the car charger interface is in its retracted position.

3. The portable charger unit according to claim 1 , further comprising at least one power connection output port operatively connected to the internal battery.

4. The portable charger unit according to claim 1 , further comprising a flashlight feature powered from the internal battery.

5. A portable charger unit for recharging at least one electronic device having a rechargeable internal battery, said portable charger unit comprising:
a charger housing internally storing a rechargeable battery;
a wall plug interface configured for engagement with a wall socket and being operatively connected to the internal battery for providing an electrical charge from said wall socket to the charger unit when said wall plug interface is operatively engaged with said wall socket and for recharging the internal battery when the charger unit is connected to said wall socket in said manner, said wall plug interface being pivotably connected to the charger housing for movement between an extended position where said wall plug interface projects outwardly away from the charger housing for use and a retracted position for storage of said wall plug interface within the charger housing;
a car charger interface configured for engagement with a car charger socket and being operatively connected to the internal battery for providing an electrical charge from said car charger socket to the charger unit when said car charger interface is operatively engaged with said car charger socket and for recharging the internal battery when the charger unit is connected to said car charger socket in said manner, said car charger interface being removably connected to the charger housing for movement between an extended position where said car charger interface extends away from the charger housing for use and a retracted position for storage of said car charger interface within the charger housing; and
at least one power connection output connector cable operatively connected to the internal battery for providing an electrical charge from the internal battery to an electronic device when said device is connected to the charger unit via the power connection output connector cable,
wherein the wall plug interface and the car charger interface, in their respective retracted positions, are each disposed within a storage cavity formed in the charger housing so that said interfaces are each contained within the general footprint of the charger housing when not in use, and the car charger interface is connected to the charger housing by a cable connected between the car charger interface and the charger housing permitting movement of the car charger interface between its retracted position where it is stored within a storage cavity in the charger housing and its extended position where it extends away from the charger housing for engagement with a car charger socket while remaining connected to the charger unit via said cable.

6. The portable charger unit according to claim 5 , wherein the at least one power connection output connector cable comprises:
a proximal end attached to the charger housing,
a distal end having an output connection interface adapted for engagement with an electronic device; and
an intermediate portion extending between said proximal and distal ends of said connector cable.

7. The portable charger unit according to claim 6 , wherein at least the output connection interface of said connector cable is storable within a storage cavity formed in the charger housing so that said output connection interface is contained within the general footprint of the charger housing when not in use.

8. The portable charger unit according to claim 5 , further comprising at least one power connection output port operatively connected to the internal battery.

9. The portable charger unit according to claim 5 , further comprising a flashlight feature powered from the internal battery.

10. A portable charger unit for recharging at least one electronic device having a rechargeable internal battery, said portable charger unit comprising:
a charger housing internally storing a rechargeable battery;
a wall plug interface connected to the charger housing for movement between an extended position where said wall plug interface extends away from the charger housing for use and a retracted position for storage of said wall plug interface within the charger housing, said wall plug interface being operatively connected to the inter
