Expandable AC power supply device
First Claim
1. An interconnectable power supply module comprising:
- a battery;
a battery charger operating to charge said battery;
a power generator operating to convert an electrical charge stored in said battery to generate output power for an external load;
a power supply plug for receiving external power from an external power source;
a power supply socket configured to couple the external power received from the external power source to an adjacent power supply module;
an external load output socket on which output power is supplied to the external load from one of the external power source and said power generator; and
a connecting terminal selectively coupling the external load output power to the adjacent power supply module.

Abstract
An interconnectable power supply module includes a battery; a battery charger for charging the battery; a power generator capable of converting an electrical charge stored in the battery to generate output power for an external load; a control unit for controlling operation of the power supply module; a power supply plug for receiving external power from an external power source; a power supply socket capable of coupling the external power received from the external power source to an adjacent power supply module; an external load output socket, selectively coupled to one of the external power source and the power generator, for providing output power to the external load; and a connecting terminal capable of coupling the external load output power to the adjacent power supply module.
