Abstract

Claims (45)

1. A portable power case comprising:

a case;

a printed circuit board (PCB) operable to connect to at least one visual indicator;

at least one port connected to the PCB; and

at least one battery removably connected to the PCB;

wherein the PCB includes at least two battery receptacles;

wherein the at least two battery receptacles are positioned parallel to one another within the case;

wherein the at least two battery receptacles are electrically connected in parallel;

wherein the PCB and the at least one battery are disposed within an open interior space of the case;

wherein the at least one battery is rechargeable;

wherein the at least one port is operable to supply power to at least one electronic device;

wherein the at least one port is operable to charge the case using at least one charging device;

wherein the PCB automatically determines a charge priority between all connected devices;

wherein the PCB modifies charge distribution based on the charge priority; and

wherein the at least one visual indicator indicates a state of charge for the at least one battery and/or the at least one charging device.

2. The portable power case of claim 1 , wherein the at least one visual indicator comprises a set of light-emitting diodes (LEDs) or at least one 5-bar liquid crystal display (LCD).

3. The portable power case of claim 1 , wherein the at least one visual indicator is operable to change color and/or flash to display the state of charge for the at least one battery and/or the at least one charging device.

4. The portable power case of claim 1 , wherein the PCB is operable to receive at least one alternating current (AC) adapter.

5. The portable power case of claim 1 , wherein the at least one port is operable to charge and discharge the at least one battery simultaneously.

6. The portable power case of claim 1 , wherein the at least one charging device is a battery producing direct current (DC) power.

7. The portable power case of claim 1 , wherein the PCB includes control electronics, wherein the control electronics include a battery management system.

8. The portable power case of claim 7 , wherein the battery management system includes a safety cutoff.

9. The portable power case of claim 1 , wherein the case is waterproof or water resistant.

10. The portable power case of claim 1 , further including a harness, wherein the battery is removably connected to the PCB via the harness.

11. A portable power case comprising:

a case;

a printed circuit board (PCB) operable to connect to at least one visual indicator;

at least one port connected to the PCB; and

at least one battery removably connected to the PCB;

wherein the PCB includes at least two battery receptacles;

wherein the at least two battery receptacles are positioned parallel to one another within the case;

wherein the at least two battery receptacles are electrically connected in parallel;

wherein the at least one port is accessibly positioned on an exterior surface of the PCB;

wherein the PCB and the at least one battery are disposed within the case;

wherein the at least one battery is rechargeable;

wherein the at least one port is operable to supply power to at least one electronic device;

wherein the at least one port is operable to charge the portable power case using at least one charging device;

wherein the PCB automatically determines a charge priority between all connected devices;

wherein the PCB modifies charge distribution based on the charge priority; and

wherein the PCB includes control electronics configured to determine a state of charge of the case and/or the at least one electronic device.

12. The portable power case of claim 11 , wherein the state of charge of the case and/or the at least one electronic device is displayed via the at least one visual indicator.

13. The portable power case of claim 11 , wherein the at least one visual indicator comprises a set of light-emitting diodes (LEDs) or at least one 5-bar liquid crystal display (LCD).

14. The portable power case of claim 11 , wherein the at least one charging device is a battery producing direct current (DC) power.

15. The portable power case of claim 11 , wherein the control electronics include a communications interface.

16. The portable power case of claim 11 , wherein the control electronics include a battery management system, wherein the battery management system includes at least one safety cutoff.
