Abstract

Claims (44)

1 . A portable power case comprising:

a housing;

a printed circuit board (PCB);

at least two battery packs connected to the PCB; and

at least one separating barrier between the at least two battery packs and the PCB;

wherein the portable power case is operable to provide power to at least one power consuming device;

wherein the portable power case includes at least one connector for at least one lead;

wherein the at least one lead includes a cable portion, wherein a flexible spring is provided around the cable portion, and wherein the cable portion and the flexible spring are held in a lid of the portable power case; and

wherein the flexible spring is configured to allow the at least one lead to bend omnidirectionally without breaking.

2 . The portable power case of claim 1 , wherein the portable power case weighs approximately 6 pounds.

3 . The portable power case of claim 1 , wherein the portable power case is approximately 13 inches long or less than approximately 13 inches long, wherein the portable power case is approximately 3.6 inches in diameter or less than approximately 3.6 inches in diameter.

4 . The portable power case of claim 1 , further comprising at least one bumper, protrusion, and/or other internal stability member between each battery pack of the at least two battery packs and the PCB.

5 . The portable power case of claim 1 , wherein the at least two battery packs are encased in at least one layer of heat barrier material.

6 . The portable power case of claim 1 , wherein the housing includes at least one flat side.

7 . The portable power case of claim 1 , wherein the portable power case is formed by at least two chemically welded corresponding sides.

8 . The portable power case of claim 1 , wherein the portable power case is configured to fit within a bag, wherein the bag is formed from a heat-barrier material.

9 . A system for providing power to at least one power consuming device, comprising:

a portable power case;

a bag; and

the at least one power consuming device;

wherein the portable power case includes a housing, a printed circuit board (PCB), at least two battery packs connected to the PCB, and at least one separating barrier between the at least two battery packs and the PCB;

wherein the portable power case includes at least one connector for at least one lead;

wherein the at least one lead includes a cable portion, wherein a flexible spring is provided around the cable portion, and wherein the cable portion and the flexible spring are held in a lid of the portable power case;

wherein the flexible spring is configured to allow the at least one lead to bend omnidirectionally without breaking;

wherein the bag is operable to close, wherein the at least one power consuming device is outside of the bag, wherein the at least one lead is operable to charge the at least one power consuming device when the bag is closed; and

wherein the portable power case is operable to provide power to the at least one power consuming device.

10 . The system of claim 9 , wherein the portable power case weighs approximately 6 pounds.

11 . The system of claim 9 , wherein the portable power case is approximately 13 inches long or less than approximately 13 inches long, wherein the portable power case is approximately 3.6 inches in diameter or less than approximately 3.6 inches in diameter.

12 . The system of claim 9 , further comprising at least one bumper, protrusion, and/or other internal stability member between each battery pack of the at least two battery packs and the PCB.

13 . The system of claim 9 , wherein the housing of the portable power case includes at least one flat side.

14 . The system of claim 9 , wherein the portable power case is formed by at least two chemically welded corresponding sides.

15 . A portable power case comprising:

a housing;

a printed circuit board (PCB); and

at least two battery packs connected to the PCB;

wherein the portable power case is operable to provide power to at least one power consuming device;

wherein the portable power case includes at least one connector for at least one lead;

wherein the at least one lead includes a cable portion, wherein a flexible spring is provided around the cable portion, and wherein the cable portion and the flexible spring are held in a lid of the portable power case; and

wherein the flexible spring is configured to allow the at least one lead to bend omnidirectionally without breaking.

16 . The portable power case of claim 15 , wherein the portable power case weighs approximately 6 pounds.

17 . The portable power case of claim 15 , wherein the portable power case is approximately 13 inches long or less than approximately 13 inches long, wherein the portable power case is approximately 3.6 inches in diameter or less than approximately 3.6 inches in diameter.

18 . The portable power case of claim 15 , further comprising at least one bumper, protrusion, or other internal stability member between each battery pack of the at least two battery packs and the PCB.

19 . The portable power case of claim 15 , wherein the housing includes at least one flat side.

20 . The portable power case of claim 15 , wherein the portable power case is configured to fit within a bag, wherein the bag is formed from a heat-barrier material.
