1. A portable, rechargeable power supply, comprising:
- a frame member;
a plurality of ground engaging wheels attached to said frame member for transporting said frame member over the ground;
a housing attached to said frame;
a rechargeable DC battery located within said housing and having a positive and a negative output terminal;
a voltage inverter, attached to said frame member and electrically hardwired to said battery output terminals, for converting DC output from said battery to an AC output and for converting AC power from an external source to a DC output for charging the DC battery;
an AC power block mounted on said frame and electrically connected to said inverter and having a plurality of AC input/output sockets;
a DC input/output female-type socket mounted on said housing and switchably connected electrically to said battery;
a plurality of photovoltaic panels attached to said frame for generating DC electrical output from solar energy; and
switching means mounted on said housing including a first switch for enabling the panels'"'"' DC output to be switched either to the battery for recharging or to a second switch, said second switch enabling the DC input/output socket to be electrically connected to either the battery or to said panels.
