I'm wondering what's in these things. I see them for something like $30 and rated for more than a kW. I don't think a 1kW 50Hz 240VAC to 120VAC transformer would meet airline baggage weight limits. So, anyone have a schematic of one of these? Thanks! Harold --=20 FCC Rules Updated Daily at http://www.hallikainen.com - Advertising opportunities available!
