I have a lovely SmartDisk PowerBook G4 Auto Adaptor that I bought with my PowerBook G4 back in 2002. Now I have a MacBook Pro and of course the tip for the charger is different. I've searched the web for ideas or an adbaptor but with no luck so thought I'd try the experts. The output of the SmartDisk G4 Auto Adaptor charger is 24v, 2.0 Amp, while the MacBook Pro's charger's output is rated ad 16.5 - 18.5v, 4.5 A max. Could the auto-charger be used with those differences if I managed to wire a MacBookPro magnetic charging tip in it? or would I blow up my batteries!
