Help! What replacement adapter can I use for iBook G4?

Hello,

I know what you mean. I'm always looking for a good quality iBook charger that doesn't cost a fortune. I'm sure that the Apple Store item is of high quality, but this is that last one that I purchased

And it has been working great. It looks like an original Apple charger has good, thick but supple quality cords. It's very nice to have the charge light, too, as this one does. That visual clue to know your Book is charged without having to wake it. I use this with both my G3 and G4 iBooks.

You giveth me too much credit. I'm just a just another student in the world of Macs.

I'm open for correction here, but from what I understand, the 45W and the 65W chargers are both approved for the iBook G3s and G4s and are plug compatible. Someone recently posted information about the 45W chargers, saying they are a bit underpowered for the 14" iBooks. I haven't noticed a problem with using the 45W charger on my 14" books.

I did read somewhere that there have been incompatibility issues with some of the many third party chargers that are available out there. I do have one of the cheap ones like the one you asked about and it seems to charge just fine, although I noticed that it runs at a higher temperature (feels hot!) than the Apple charges I own. The Apple chargers may have higher refined charging electronics that could lend itself to better battery life, but that's just a guess.

I'm sure there is someone on Apple Discussions that knows more than I about these subjects. Can anyone provide some additional insight?

Hi all,
I generally use the 45W and the 65W interchangeably and since I always have a working battery in I can't see where it makes much difference. Iactually prefer using the type that look like this:

Mostly to get the LED charge light, which I find very helpful diagnostically.

I noticed that it runs at a higher temperature (feels hot!) than the Apple charges I own.

Which is hard to do since those chargers run very hot. In fact it's a bad idea to ever cover them with anything when they're running. (Done that! "Is something burning?")
I used to buy them from China on eBay but recently it seems like the same items ship from the US. I also only deal with sellers with a 99%+ positive feedback rating.

I'm almost certain you want to go with a minimum requirement at the least.

In other words, find out what adapter wattage is included in the spec's.
Find an equivalent or higher... i.e. A 65w adapter will not damage a device with a 45w spec while a 45w adapter may damage a device with a 65w spec (the device won't have enough power).
