Mark, I use a Sherpa100. Good pack, but the output voltage goes under 12V way before the pack is empty, so the KX3 will not let you use full power after a while. The KXPA100 is not as picky, so you can easily run a KXPA100 at 50W on the Sherpa100 until the end of the pack's power. It's a pretty good solution imho!
I have not tried to use the Laptop 19V output with a regulator, that would be another approach. But on a portable power pack, you probably don't want a linear convertor, and a switched buck convertor will introduce noise unless you're not very careful when you design it... In my experience, the Sherpa100 is a fine solution. If you already have one, just get a cigarette lighter to anderson adapter and try it out!
