Can anyone help me. I've been using a Kerio Auto/Air Adapter with my IBM and had no hassles. The new Compaq runs at 18.5V at 3.5Amp though. The Kerio offers 18V or 19V selection, but no 18.5V. Can anyone comment on using either the half volt lower or higher to run and recharge the laptop on the move? PS: No comments on using an inverter, I would really prefer to retain the adapter as it seems to be a neat set up for my needs. Thanks all.

Well, if the internal battery requires 18.5V to charge it then 18V won't do the trick.
If it was my Compaq I'd try 19V and see if things get too hot anywhere.
But, its your computer and your risk ;-)

I was thinking along them lines and then decided that since I will have access to 240V along the way, I may just try to run the computer on 18V without charging the battery. Don't suppose anyone has any idea what effect a lower voltage may have?

A lower voltage shouldn't harm anything.....
A higher voltage might- but then when you're only talking half a volt, I don' think it too much of a concern.
I'd try the low voltage first.

A couple of thoughts:

Measure the actual voltage put out by the adpter at both settings in case they're not exactly 18.0 and 19.0 - you may be lucky and one of them is close to 18.5.

Check the voltage being put out by the 240v adapter and match this (again it may not be 18.5) I have assumed in both cases that they are switch mode power supplies and will show the same voltage with and without load.

As a previous post said, it's unlikely that a lower voltage will do any harm but if too low either the computer won't run or the battery won't charge (or both)
