I should mention at this point that I know nothing about >currents and what is potentially damaging to the computer, so I would be >glad of any advice to make sure :) Amperage indicates maximum current draw. You can't burn something out with too much current. Voltage is different :) Yeah, the Duos, the 190/5300, the 1x00 series (including Kanga G3) all can take the same. Pretty much so do the G3 laptops (up to Pismo) and the first iBooks. The later ones ned 45W, the 2400 takes 36W iirc and the Duo's need something under 30W I think. So back-compatible, not really forwards-compatible I think, that is Andrew
