Review: Bought this about a month ago as a back-up adaptor. When used on my Powerbook G4 and my wife's iBook G4, it does not charge them when in operation. It supplies power so that the units are functional when plugged in, but it will only charge the units when they are closed or turned off. I'd give this a one star, but at least it powers them when they're on, even without the charging. 
 Polarity: Positive
