Basically, if you double the voltage you halve the amperage.
in other words 6 volts at 10 amp current draw, gives you a 5 amp at 12 volt capability. The old style was just like a transformer. the "in" circuit is separate from the "out" circuit and the ratio between "in" and "out" depends on the number of windings in each. Just like your ignition coil.

In this case, twice as many windings on the "out" as the "in" gives you double the voltage. How ever nothing is free, so as said, the amperage able to be delivered is halved. I hope that helps.
