I'm a bit new to this stuff so please excuse my elementary question. A gas generator rated at 700 watts and 120V puts out about 5.8 amps. Is it possible to step down the voltage to 12V with a power supply and make available 58 (DC) amps to draw?? Or is the excess voltage simply lost? Thanks.
Added:
The Generator has an AC output of 120V 1000W max (rated @ 8.3A).
Usage will be charging high capacity lithium Polymer batteries.
Basically I would like to have 20A available to charge.
