Yes, he used some sort of transformer for house current. The lights work great. He used a B737-200 gasper fan for the fresh air vents, but he doesn't use them. They are way too loud for practical use, it's a cool conversation piece though! If you flick a switch, the O2 masks drop, but it's a pain to get them packed again.
Anyway, good to hear you found a place for the bev cart!
