I bought a iBook 700MHz iBook last year. It came with what says a 45W Power Adapter. It is the square white unit with both 2 prong clip and a 3 prong power cord. However, looking on both eBay and the Apple site, the only power adapter being sold are the 65W units. Have I been given an incorrect adapter or does it matter?

Thanks,

X

How do you know your adapter is only 45W? couldn't find anything on mine saying this... anyway the 65W is definitely the one you need for your iBook.

My iBook 700 came with a 45W one.

The newer iBooks, Powerbooks come with a 65W.

If you buy them off the shelves, they'd probably be a 65W one too.

Doesn't really matter much, me thinks.

The 12˝ Powerbook uses a 45W power adapter, the 15˝ and 17˝ use the 65W power adapter. It might be tied to battery size. 12˝ iBooks have a 50-watt-hour battery and the 14˝ iBooks have a 61-watt-hour battery. Do the 14˝ iBooks use the 65W power adapter while the 12˝ iBooks would use a 45W? That would be a guess, but according to this I'm guessing they're standardizing on the 65W power adapter, which they explicitly specify is for all Dual USB generation iBooks and Titanium G4 Powerbooks.

I have both a 1.25GHz 15" PowerBook and a 600Mhz G3 iBook. The iBook shipped with a 45w adapter, while the PowerBook shipped with at 65w adaptor (as others have stated).

I have used the 65w adapter with the older iBook with no problems at all - everything seems to work ok (as suggested).

i haven't used the 45w adapter with the G4 Powerbook though . I'd think that the Powerbook with its 1.25GHz G4 would have significantly higher power demands compared to the iBook with its cooler running 600 G3, smaller 12" screen and slower HD.

Replacement white-brick styled Apple Power adaptors off the shelf are 65w (provided that they are not very old stock)- I purchased another so I can leave one at work.

How to tell: looking at my 65w version now, on the top of the adapter where the AC in is, it says:
"Apple 65w Portable Power Adaptor", then has 65W in a small square icon. The output is rated 24.5v @2.65A.

45w - In the same position as above, it simply reads "Apple Portable Power Adaptor". The output is rated 24v @ 1.75A.
