We ended up buying a 12V to 19V converter:

I haven't dug into the rules closely enough to find anything that rules those out, but I suppose I'll do that while I'm studying up for robot inspecting.
We might end up using our mentor's TK1 instead. It's smaller, lighter, runs on 12V, and it talks to the cameras we bought unlike the TX1.
