Travel lighter with Apple's power adapter
Authored by: donaciano on Jul 06, '06 10:43:51AM

I would warn people to watch out for adaptors that require being plugged in a certain way.

My Camcorder plug is ALMOST the same as the Apple one, except that one part of the 8 on the plug is a bit more square. Looks like DO, following the wire to the plug, the D side has a larger connector than the O side. So at the wall you'll see |I ... which means if I plug the Apple adaptor into my Camcorder brick I could plug it in backwards and fry something. So watch out for that, some devices care about polarity. Maybe some of you are old enough to remember blenders running backwards if you plugged them in the wrong way... and of course toasters that froze your bread when plugged in backwards.

Actually, you can't fry something by reversing the polarity as long as it's AC. The live and neutral terminals constantly switch at 50 or 60hz, reversing the polarity. Reversing the polarity on DC stuff will usually damage it!
