Ron,
Finding a 19.x power DC/DC converter won't be easy, but you can get
close looking for a power supply that as plus and minus 12v (or 24v) and
a 5v that is separate from the higher voltage output. Buck the 5v supply
against the 24v and you will have something close to 19v. I haven't
tried this with switching supplies, but it worked with analog supplies. \
Another way, though not as elegant, is to buy a 24v converter and add a
regulator to the output to get the voltage you need.
Either of these will cost more than an inverter to plug you power supply
into.
Peace,
Pat
