Abstract

A portable wireless charging system is incorporated inside a carrying device that has a plurality of walls and an interior. The portable wireless charging system has a transmitter positioned at a first fixed location at an inner surface of one of the walls, a mobile power supply positioned adjacent the transmitter and electrically coupled to the transmitter, and a receiver positioned at a second fixed location at an outer surface of the one of walls, with the second fixed location aligned with the first fixed location. A barrier is positioned between the transmitter and the receiver, and a first pocket positioned at the outer surface about the second fixed location. A portable device that includes a battery to be charged can be retained inside the first pocket to be charged.

Claims

1. A portable wireless charging system, comprising:

a carrying device having a plurality of walls and an interior;

a transmitter positioned at a first fixed location at an inner surface of one of the plurality of walls inside the carrying device;

a mobile power supply positioned adjacent the transmitter inside the carrying device and electrically coupled to the transmitter;

a receiver positioned at a second fixed location at an outer surface of the one of the plurality of walls outside the carrying device, with the second fixed location aligned with and directly opposite to the first fixed location;

a barrier positioned between the transmitter and the receiver; and

a first pocket positioned at the outer surface of the carrying device about the second fixed location.

2. The system of claim 1, further including a power supply pocket positioned at the inner surface about the location of the mobile power supply, with the mobile power supply retained inside the power supply pocket.

3. The system of claim 1, further including another transmitter positioned at a third fixed location at the inner surface, another receiver positioned at a fourth fixed location at the outer surface, and a second pocket positioned at the outer surface about the fourth fixed location, with the first and third pockets having different sizes.

4. The system of claim 1, wherein the transmitter includes a magnetic coil.

5. The system of claim 4, wherein the receiver includes a magnetic coil.

6. The system of claim 1, further including a portable device that includes a battery to be charged, the portable device retained inside the first pocket.

7. The system of claim 1, wherein the carrying case is a piece of luggage.

8. The system of claim 1, wherein the carrying case is a box.
