1. A portable power case comprising:
a case;
a printed circuit board (PCB);
at least two access ports connected to the PCB; and
at least one battery connected to the PCB;
wherein the case comprises a lid and a base that form a housing;
wherein one or more of the at least one battery is in a battery housing;
wherein the battery housing includes a latch and a battery lid, wherein the battery lid includes a hole and a connector installed in the hole;
wherein the at least two access ports include a first female access port and a second female access port, wherein a first shape of a first opening of the first female access port is a first composite shape, wherein the first composite shape includes a first circular portion and a first flat portion, and a second shape of a second opening of the second female access port is a second composite shape, wherein the second composite shape includes a second circular portion and a second flat portion, and wherein the first flat portion angles a first corresponding cable connected to the first access port away from a second corresponding cable connected to the second access port; and
wherein the at least two access ports are operable to supply power to at least one access port electronic device and charge the portable power case using at least one charging device.
 
13. A portable power case comprising:
a case;
a printed circuit board (PCB);
at least two access ports connected to the PCB; and
at least one battery connected to the PCB;
