The one I have, has a length of resistor wire and draws 100A from a 12V battery for as long as the switch is pressed. They say the aim it to not go below 10V in 5 seconds, or there-abouts

   Before you spend money on this thing, let
   me pick one up and do an autopsy on it.
   I didn't get a really close look at the
   last one I saw but I'm skeptical of
   its performance claims.

   I'll find out.
