My laptop uses 18 volts... Right now; i use an inverter to go to 110, then use
hte laptops power supply to return to 18.

Seems like if I could just go 12vdc to 18vdc it'd be more effecient.

Thoughts?

And if so; any clues on where I can find info on building something like this?

Don't bother, just stay as you are with the inverter, it really isn't worth
it. To get the amps you need to run a laptop, the circuitry is more costly
than what you are doing now. This post will result in howls of protest from
the electronics whizzkids, but I'm telling you, it's a jungle out there!

Check with Radio Shack. I bought a universal Laptop power supply from them that
workes fine.

From a 12-volt source?

If you are after a simpler alternative these may help, they are in
Australia, but I'm sure they will be available somewhere in the states:

what the hell? you already have the inverter. something else could be
more
efficient, but not THAT much more.

Cool; thanks. I've found a few others, "Radio shack" (a electronics chain) has
something,a nd iGo has a highly recommended unit.

However, I gotta think these units that do multiple voltages aren't as effecient
as going directly from 12vdc to 18vdc.

Anyone know for sure?

Sounds great, but at $75+ what is the point?

It doesn't generate RFI so you can use it at the same time as your HF
radio.

Check the wattage requirements of your notebook PC. The RS adapter didn't
have quite enough juice to power my H-P, and especially so when charging the
PC's battery.
