I have Ti/Al Powerbook purchased in NY, USA. It has the regular two-unequal-prong power outlet. Can I use my PBs in Japan. I know Japan and USA are similar in frequency (50hz/60hz) and voltage (100 for Japan and 120 V for USA). Almost all of Japanese electricnics are tuned for 50hz/60hz and 100 to 120 V. But, I am not sure about the shape of the power outlet. I heard some countries use equal prong outlet while some use unequal prong like USA. I should not be asking this question as I am originally from Japan (but I've been in states more than 10 years and my memory about it has been very hazy (or almost wiped out) at best.
