Universal power supply system

A universal power supply system comprising:

• a housing containing a power supply configured to generate a predetermined direct current output sufficient to simultaneously power a plurality of direct current powered devices coupled thereto;
• a plurality of uniformly dimensioned sockets disposed in a wall of the housing and electrically coupled in parallel with the direct current output of the power supply;
• a plurality of power cables, each power cable having a first plug and a second plug connected at opposing ends;
• the first plug adapted to couple with any of the plurality of sockets;
• the second plug adapted to be received by a socket specific to at least one of the plurality of direct current powered devices;
• a voltage regulating circuit disposed in either the first or second plug, the voltage regulating circuit adapted to provide an output voltage compatible with the at least one direct current powered device.
