I just received an iBook I bought used on eBay (got a great deal, and so far it looks good!). Only problem is- the adapter that came with it is like only 3-4 feet long (the adapter piece JUST reaches the ground from my desk). I plugged in the 'extension' cord from my Macbook Pro's adapter and that seems to be working fine, but now I can only charge my MBP with the little plug thing. So my question is this: can I use any power 'extension' cable that fits (i.e. a random black one I just found) to plug the adapter into the wall? Like this:http://www.amazon.com/Universal-Power-Cord-Two-Prong-Misc/dp/B000J0AON4 It would be great if I could, since this would save me the trouble of switching cords or buying another cord to connect the adapter.
