Did you try Captain Cheapo's solution instead?
Authored by: bogdescu on Nov 14, '08 06:53:18PM

Standard, radioshack-available boombox powercords work on Apple laptop power bricks.

If I'm not mistaken, the third (ground) prong on the Apple power cords is superfluous - there are only two wires going into the brick anyway, the third one is "lost in translation".

I've been replacing the standard Apple powercords with these on my powerbooks for years. They are lighter, thinner, and they set you back a whopping buck when you loose them. Yes, you can also get them in white. If you forgot to get one, there's always a boombox around to use as a temporary organ donor.

The other sweet thing about these cables is that they are globaly available in "localized" versions (i.e. with the local variation of the power plug on the wall end), so you can get them them in - say - Ireland, or Poland and use them instead of an international adapter.

I think the ground is used. I have heard that using the grounded wire can help reduce static electricity on the aluminum casing of a MacBook Pro, and if you'll notice, the round metal knob thing that the cord attachment slides into on the brick contacts a metal part in the three pronged connector attachment that doesn't exist in the two pronged connector attachment.

With that being said, I'm not so sure if the ground will do much on an airplane. :-)

sure does. the earth ground keeps the body of the laptop from buzzing. boombox cords will not help this. it should also be the case on the plane, since the ground is probably wired to the plane chassis.
