11. The case of claim 10 further comprising an external electrical outlet carried by the housing and electrically coupled with the electrical connector to provide power to outside the case;
wherein the external electrical outlet is available to power an external device when the electrical connector is coupled with the electrical power source.
12. The case for storing tools of claim 10 further comprising a light for indicating a characteristic state of the battery charger.
13. The case for storing tools of claim 10 further comprising a translucent portion carried by the housing for providing visibility inside the case to view a charge indicator located on the battery charger.
14. The case for storing tools of claim 11 wherein the connector is a plug mounted on the housing.
15. The case for storing tools of claim 11 wherein the connector is a plug mounted on an end of an electrical power cord electrically coupled with the internal electrical outlet.
16. The case for storing tools of claim 10 wherein the compartment for storing the electrical power cord further includes projections to wrap the electrical power cord around.
17. The case for storing tools of claim 10 wherein the compartment for storing the electrical power cord further includes a retracting device to retract the power cord into the compartment.
18. The case for storing tools of claim 10 further including a vent for preventing heat from building up within the case.
19. The case for storing tools of claim 10 further including a circuit protection device electrically coupled with the electrical connector.
20. A method of charging a power tool battery comprising the steps of:
(a) disposing a battery charger having an electrical plug inside a case;
(b) engaging the power tool battery with the battery charger;
(c) plugging the electrical plug into an AC electrical outlet carried within the case and coupled with electrical circuitry inside the case;
(d) closing the case; and
(e) electrically coupling the electrical circuitry with an AC electrical power source, wherein the AC electrical power flows through the electrical outlet and powers the battery charger inside the case to charge the power tool battery without needing to open the case and remove the power tool battery and battery charger.
