Title: output is much higher than what should be
Review: I got one from Amazon yesterday. I heard people saying inaccurate voltage output, so I tested it in my lab. I need 4.5v for my CD player, and I got 7.3 volts when I switched to 4.5v. Even 3v position gave me 5.4v output. I am not sure whether I can plug this in my CD player. Good thing is that the screws are special type such that people like me (with some knowledge) cannot not do anything to it. It will be a waste for me.
