I just purchased a piece of equipment for my aquarium. The pump for this runs on DC 24v 1 amp 13W. I ordered this piece from overseas (I am in the US) and it is coming with a 220v 50hz power brick. I realize I can just get a 110v 60hz power brick with the specs I need, but I guess my question is what would happen if I tried to use the supplied one and just changed the plug to fit the socket. I know most power bricks these days are actually capable of converting 110 up to 220 but could this one be specific? Could I easily tell by pulling it open? Its not here yet or I would post pics.
