Abstract

A portable power charger is provided for wirelessly charging an electronic device from a rechargeable battery internally disposed within the charger. An attachment system is also provided for connecting the electronic device to the portable charger so that the respective wireless transmission components therein are properly aligned for optimal and efficient wireless charging. The alignment system can comprise an arrangement of magnets on each of the portable charger and the electronic device, whereby said magnets are geometrically arrangement is spaced apart relationship to one another. The magnetic arrays on each of the portable charger and the electronic device are complementary to ensure the proper positioning of one relative to the other. The electronic device may alternatively use an attachment ship secured thereto with a magnet array complementing the arrangement on the portable charger, or a protective case with a built in magnetic arrangement at a predetermined location and orientation.

First claim

What is claimed is:

1. A wireless charging kit for connecting and aligning an electronic device having a rechargeable internal battery and a wireless receiver defining a wireless reception area to a power source for wireless charging of the internal battery of said electronic device, said kit comprising:
a portable power charger comprising:
a charger housing internally storing a rechargeable battery;
a wireless transmitter disposed within the charger housing and operatively connected to the rechargeable battery capable of wirelessly transmitting power to an electronic device, said wireless transmitter defining a wireless transmission area; and
at least one magnet positioned on or near an outer surface of the charger housing at a predetermined location relative to the wireless transmission area; and

an attachment chip adapted for attachment to the electronic device, said attachment chip including a number of magnets complementing the number of magnets on the charger housing, whereas when the attachment chip is attached to the electronic device, the magnets are positioned at respective locations relative to the wireless reception area for said electronic device such that when the electronic device is connected to the portable charger via interaction of the respective magnets, the wireless receiver of the electronic device is aligned with the transmitter of the portable charger for wireless exchange of a power from the transmitter to the receiver, and
wherein said portable charger maintains physical and wireless connection with the electronic device during collective transport of the portable charger and the electronic device.

2. The wireless charging kit according to claim 1 , wherein the at least one magnet on the charger housing comprises a plurality of magnets geometrically arranged on or near the outer surface of the charger housing in spaced apart relationship to one another; and
wherein the attachment chip includes a complementary number of magnets arranged in the same geometrical arrangement and space apart relationship as for the plurality of magnets on the portable charger.

3. The wireless charging kit according to claim 2 , wherein the geometrical arrangement of magnets on the portable charger defines a central space generally aligned with the wireless transmission area so that the magnets do not interfere with transmission from the wireless transmitter.

4. The wireless charging kit according to claim 2 , wherein the plurality of magnets comprises four magnets generally arranged to define a square.

5. The wireless charging kit according to claim 1 , wherein the attachment chip comprises a generally flat disc having an attachment surface adapted for attachment to a surface of the electronic device.

6. The wireless charging kit according to claim 5 , wherein the attachment chip has an adhesive material on the attachment surface for attaching the chip to the electronic device.

7. The wireless charging kit according to claim 5 , wherein the disc defines an opening with the number of magnets spaced therearound, said opening generally being aligned with the wireless reception area associated with the wireless receiver of the electronic device when the attachment chip if attached to said electronic device so that the magnets on the attachment chip do not interfere with reception of wireless signals by the wireless receiver.

8. The wireless charging kit according to claim 7 , wherein the disc is shaped as a square with a circular opening.

9. The wireless charging kit according to claim 7 , wherein the disc is shaped as a circle with a circular opening.

10. The wireless charging kit according to claim 7 , wherein the disc is shaped as a triangle with a circular opening.

11. The wireless charging kit according to claim 1 , wherein the attachment chip is adapted for mounting within a case designed to be fitted onto the electronic device, the magnets of the attachment chip being positioned relative to the wireless reception area of the electronic device in a predetermined location so that when the electronic device is connected to the portable charger via interaction of the respective magnets, the wireless receiver of the electronic device is aligned with the transmitter of the portable charger for wireless exchange of a power from the transmitter to the receiver.

12. A wireless charging kit for connecting and aligning electronic devices for wireless transmission of battery power, including during collective transport of said electronic devices, said kit comprising:
a portable power charger comprising:
a charger housing internally storing a rechargeable battery;
a wireless transmitter disposed within the charger housing and operatively connected to the rechargeable battery capable of wirelessly transmitting a power to an electronic device, said wireless transmitter defining a wireless transmission area; and
at least one magnet positioned on or near an outer surface of the charger housing at a predetermined location relative to the wireless transmission area; and

an electronic device comprising:
an electronic device housing internally storing a rechargeable battery;
a wireless receiver disposed within the electronic device housing and operatively connected to the rechargeable battery capable of receiving the power and directing it to the rechargeable battery, said wireless receiver defining a wireless reception area; and
a number of magnets complementing the number of magnets on the charger housing, said magnets being positioned on or near an outer surface of the electronic device at a predetermined location relative to the wireless reception area,

whereas when the electronic device is connected to the portable charger via interaction of the respective magnets, the wireless receiver of the electronic device is aligned with the transmitter of the portable charger for wireless exchange of the power from the transmitter to the receiver and said portable charger maintains magnetic and wireless connection with the electronic device during collective transport of the portable charger and the electronic device.

13. The wireless charging kit according to claim 12 , wherein the at least one magnet on the charger housing comprises a plurality of magnets geometrically arranged on or near the outer surface of the charger housing in spaced apart relationship to one another; and
wherein the electronic device includes a complementary number of magnets arranged in the same geometrical arrangement and space apart relationship as for the plurality of magnets on the portable charger.

14. A portable power charger for recharging an electronic device having a rechargeable internal battery and a wireless receiver, including during collective transport of the portable power charger and said electronic device, said portable power charger unit comprising:
a charger housing internally storing a rechargeable battery;
a wireless transmitter operatively connected to the rechargeable battery capable of wireless transmitting a power to an electronic device attached thereto, said wireless transmitter defining a wireless transmission area; and
a magnet positioned on or near an outer surface of the charger housing at a predetermined location relative to the wireless transmission area and being adapted for interaction with an electronic device having at least one of a magnet and a metallic piece so positioned on the electronic device such that when said electronic device is attached to the portable charger via the magnet in the portable charger and the magnet or metallic piece in the electronic device, the wireless receiver in said electronic device is aligned wit
