[Shop-talk] Dewalt 12v power supply

[Hoerning, Timothy]

I think this will do what you need.   It’s kinda big and bulky, but I would figure that’s so the 20V-12V converter can be heat sinked.   It says it’s a buck inverter, so it should be efficient.  You would need to wire up the cigarette lighter jack.

This one is more compact, but looks like a home-made 3d-printed design.

You could also get something like this and pick the regulator you want.

LMK if you want to talk about it.
