    I have recently noticed that I have both 65 and 45 watt chargers and they both work on the Powerbook G4 A1095.

    Which is the correct adapter and am I harming the computer by using them. Thanks for your time.

    They will both work. On Apple products you can use power adapters that are a higher voltage than intended, just not a lower voltage.

    So the one that came with it would be 45watts then?

    I think so. If the 45watt one works that sounds like the one that came with it.

    thanks I had lost the original one I got with it and found replacements and did not notice until recently they were all different watts.

    The Aluminum PowerBooks require the 65W charger. Titanium Powerbooks, except for the 1GHz DVI use the 45W charger, but will step down a 65W.

    Long term use of the 45W charger can damage the charging circuitry of the Aluminum PowerBooks.

    You'll notice that you maintain a charge with the 45W charger, but while using the Mac it will not actually charge. It WILL charge if the Mac is off or asleep but it will be very slow.

    Do yourself a favor and use the 65W. That's what the spec is for the Aluminum PowerBooks.

    My 12" powerbook came with a 45W brick. I bought a second one to keep at work and it was 65W. They both work fine for me.

    a little off topic but would it be the same for iBooks as well with the charger?

    iBook G3s are 45W and the G4s are 65W I believe.
