Having toasted the original charger of a Powerbook G4, I substituted charger "no name" that looks much like the original (same square format, even small tabs to manage the cable). The only drawback is that it found no LEDs indicating the activity, be it on the charger itself or on the plug that connects to the PC, it is very unfortunate. However, given the price, I think we can say that this is nitpicking.
