Abstract

Systems, methods, and articles for a portable power case are disclosed. The portable power case is comprised of at least one battery and at least one PCB. The portable power case has at least two access ports, at least two leads, or at least one access port and at least one lead and at least one USB port. The portable power case is operable to supply power to an amplifier, a radio, a wearable battery, a mobile phone, and a tablet. The portable power case is operable to be charged using solar panels, vehicle batteries, AC adapters, non-rechargeable batteries, and generators. The portable power case provides for modularity that allows the user to disassemble and selectively remove the batteries installed within the portable power case housing.

First claim

The invention claimed is:

1. A portable power device comprising:
a case;
a printed circuit board (PCB);
at least two leads or at least one access port and at least one lead connected to the PCB; and
at least one battery connected to the PCB;
wherein the at least two leads or the at least one access port and the at least one lead are operable to supply power to at least one electronic device;
wherein the at least two leads or the at least one access port and the at least one lead are operable to charge the portable power device using at least one charging device;
wherein the portable power device is connected to the at least one charging device through a cable with a battery protector;
wherein a spring is provided around a cable portion of the at least two leads or the at least one lead; and
wherein a portion of the spring is positioned outside the portable power device and another portion of the spring is positioned inside the portable power device.

2. The portable power device of claim 1 , wherein the case comprises a lid and a base.

3. The portable power device of claim 1 , wherein the at least two leads or the at least one lead are operable to be flexed in a multiplicity of directions.

4. The portable power device of claim 1 , wherein the battery protector prevents the portable power device from draining the at least one charging device.

5. The portable power device of claim 1 , wherein the battery protector is connected to the vehicle battery using ring terminals, alligator clips, or a North Atlantic Treaty Organization (NATO) slave adapter.

6. A portable power device comprising:
a case;
a printed circuit board (PCB);
at least two leads or at least one access port and at least one lead connected to the PCB; and
at least one battery connected to the PCB;
wherein the at least two leads or the at least one access port and the at least one lead are operable to supply power to at least one electronic device;
wherein the at least two leads or the at least one access port and the at least one lead are operable to charge the portable power device using at least one charging device;
wherein the PCB includes control electronics configured to determine a state of charge of the portable power device and/or the at least one electronic device; and
wherein the at least two leads or the at least one lead includes a connector portion and a cable portion, and
wherein a spring is provided around the cable portion of the at least two leads or the at least one lead, wherein a portion of the spring is positioned outside the portable power device and another portion of the spring is positioned inside the portable power device.

7. The portable power device of claim 6 , wherein the at least two leads or the at least one lead are operable to be flexed in a multiplicity of directions.

8. The portable power device of claim 6 , wherein an exterior surface of the case includes at least an indicator.

9. The portable power device of claim 6 , wherein the control electronics include at least one processor, and wherein one or more of the at least one processor is programmed to periodically measure the state of charge and send state of charge information to at least one remote device.

10. A portable power device comprising:
a case;
a printed circuit board (PCB);
at least two leads or at least one access port and at least one lead connected to the PCB;
at least one universal serial bus (USB) port connected to the PCB; and
at least one battery connected to the PCB;
wherein the at least two leads or the at least one access port and the at least one lead and the at least one USB port are on the case;
wherein the at least one USB port, the at least two leads, or the at least one access port and the at least one lead are operable to supply power to at least one electronic device;
wherein the at least two leads or the at least one access port and the at least one lead are operable to charge the portable power device using at least one charging device;
wherein a spring is provided around a cable portion of the at least two leads or the at least one lead; and
wherein a portion of the spring is positioned outside the portable power device and another portion of the spring is positioned inside the portable power device.

11. The portable power device of claim 10 , wherein the case comprises a lid and a base that form a housing having an interior surface, an exterior surface, and an open interior space.

12. The portable power device of claim 11 , wherein the interior surface is lined with foam, a material that is resistant to electromagnetic interference, and/or a material that is resistant to radio frequency interference.

13. The portable power device of claim 10 , wherein the case is waterproof or water resistant.

14. The portable power device of claim 10 , wherein the at least two leads or the at least one lead are operable to be flexed in a multiplicity of directions.

15. The portable power device of claim 10 , wherein the connector portion has an ingress protection (IP) rating of IPX6, IPX7, or IPX8.

16. The portable power device of claim 10 , wherein a layer of heat shrink tubing is placed around the cable portion before the spring is provided around the cable portion.

17. The portable power device of claim 10 , wherein the at least one battery is rechargeable.

18. The portable power device of claim 10 , wherein the at least one access port is a circular connector.

19. The portable power device of claim 10 , wherein the at least two leads include a first lead and a second lead, and wherein the first lead and second lead are staggered vertically and horizontally.
