3. The portable charging system of claim 1, wherein the portable apparatus comprises one of a purse, a backpack, a piece of luggage, and a briefcase.

4. The portable charging system of claim 1, wherein the power source comprises at least one of a battery, a power outlet, and a wireless transmit antenna.

5. The portable charging system of claim 4, wherein the battery is integrated within the portable enclosure.

6. The portable charging system of claim 4, further comprising a power connector configured to couple the power outlet to at least one of the transmit antenna and the battery.

7. The portable charging system of claim 6, wherein the power connector comprises a removable cord configured to couple to an electrical connector on the portable enclosure.

8. The portable charging system of claim 6, wherein the power connector comprises a retractable cord configured to retract into the portable enclosure and extend out from the portable enclosure.

9. The portable charging system of claim 1, further comprising at least one coil, wherein each coil is positioned proximate a storage area within the portable enclosure and configured to receive power from the power source and transmit power via inductive coupling to a receiver positioned within the storage area.

10. The portable charging system of claim 1, further comprising a plurality of antennas positioned within the portable apparatus, wherein at least one antenna is oriented in a different plane than at least one other antenna.

11. The portable charging system of claim 1, wherein the at least one antenna comprises two concurrently operable and spatially separated antennas.

12. The portable charging system of claim 1, further comprising at least one wireless receive antenna, wherein each wireless receive antenna is configured to receive power from an associated transmit antenna and charge an electronic device operably coupled thereto.

13. The portable charging system of claim 12, wherein the electronic device comprises at least one of a cellular telephone, a camera, a media player, a gaming device, a tool, navigation device, a headset, and a toy.

14. The portable charging system of claim 12, wherein the power source comprises at least one of a battery and a power outlet.

15. The portable charging system of claim 14, wherein the battery comprises at least one of chargeable battery and a replaceable battery.

16. A portable charging system, comprising:

an antenna configured to receive power from a power source and transmit power within a near-field; and

a portable apparatus having at least one receive antenna coupled thereto and positioned within the near-field, wherein each receive antenna is operably coupled to at least one connection port positioned within the portable apparatus and each connection port is configured to physically couple to a charging port of a chargeable device.

17. The portable charging system of claim 16, wherein each connection port comprises one or more connectors configured to physically couple to a charging port of a chargeable device.

18. A method of charging a chargeable device within a portable apparatus, comprising:

receiving power in at least one antenna integrated within a portable apparatus; and

wirelessly transmitting power from the at least one antenna to at least one other antenna positioned within a near-field of the at least one antenna and coupled to a chargeable device.

19. The method of claim 18, wherein receiving power in at least one antenna integrated within a portable apparatus comprises receiving power in at least one transmit antenna integrated within the portable apparatus.

20. The method of claim 18, wherein receiving power in at least one antenna integrated within a portable apparatus comprises receiving power in at least one repeater antenna integrated within the portable apparatus.

21. The method of claim 18, wherein wirelessly transmitting power from the at least one antenna to at least one other antenna comprises wirelessly transmitting power from the at least one antenna to at least one receive antenna coupled to a chargeable device.

22. The method of claim 18, wherein wirelessly transmitting power from the at least one antenna to at least one other antenna comprises wirelessly transmitting power from the at least one antenna to at least one receive antenna coupled to a chargeable device if the chargeable device is in need of power.

23. The method of claim 18, wherein receiving power in at least one antenna integrated within a portable apparatus comprises receiving power from at least one of a battery, a power outlet, and a transmit antenna.
