[Shop-talk] Dewalt 12v power supply

[Jimmie Mayfield]

If you're willing to solder your own cigarette plug or socket, you can 
find DC-to-DC converters for Dewalt batteries.  This one looks like 
it'll do the trick:

As a buck converter, it ought to be reasonably efficient (and indeed it 
claims 97% eff at half-load). Still, if you're going to drive this thing 
at 100+ watts, you might want to make sure it has adequate ventilation 
(or mount a small 12V fan).
