can I use THIS power adapter with THIS iBook?
Hi there, wondering if someone can help me out.
I've got a G4 iBook, dual USB with a broken power adapter. I'm wondering if this other power adapter I have will work with it, or if i risk frying stuff.
The original is a 45W, 24.5V, 1.875 Amp (see picture, white adapter)
The "replacement", which is one year older is: 24V, 1.874 Amp, and I believe 45 Watt. It doesn't say 45 watt but I think all of these "UFO" adapters were... The plug fits well in the computer.
I don't see why it wouldn't work, but I just wanted to check before trying.
Thanks!
Niels

edit: OK, I was wrong. The power adapter in the second picture seems to be the right one. There were two versions of the UFO power adapter: one with a big plug for the G3 PowerBooks and one with a smaller plug for the iBooks. So It should work!
It will probably ruin your battery life over time.
Why do you think this will happen?
The 24 V (or 24.5 V, the difference is negligible) volts from the power adapter are transformed to 12 V inside the iBook by the charging circuitry, and the battery itself has about 10.5 volts (more volts are needed to charge a battery). Important is the max current the power adapter can deliver, which is 1.874 (or 1.875) amps. Electrically, both power adapters are the same (1.874 A * 24 V = 45 W).
