That's a clever trick! Many newer laptop power supplies output 15v or
more, and a solar controller can knock this down and control it to
become a proper battery charger. The laptop supplies are pretty well
sealed, which solves the dirt/moisture problems. They are universal
input (90-250vac), which means no voltage doubler so they work on DC.

The only drawback is a fairly low power level, so a bigger accessory
battery is needed to cover those long drives on a dark and rainy night.
