There's a new one at Costco for $35 that's made for the home, so it should be a welcomed overkill in a small, van space.
No plug, it's powered by a sealed, 5-yr battery. The box says that 5yr is about the life of the detector's ability to detect CO safely, or something like that and it should be replaced. Nice and compact unit.
I have the one that plugs into the outlet from last year ($27 on sale), also at Costco and by the same company. Weird, but Kill-A-Watt registered 0.00 watt. The new/battery unit is 70% the size of the old one.
