I bought one of those power cords from Amazon.....really, really good buy, especially for my external hard drives (they were dual voltage).
The problem with a US power strip is that it isn't rated for 220-240V - you could end up frying not only the strip, but damaging anything plugged into it (even if the items are dual voltage).
The adapters PickledSakura mentioned are fine, but you're more limited if you have a few things to plug in. For the money, go with the power strip you found.
That is exactly why I thought of going with this one, cause when I went to The Source, they informed me about the whole power strips here in Canada (I know I mentioned US power strip but we're all the same when it comes to electronics, region 1, 110-120V, etc.
Would still like other opinions if I'm honest just so I can get perspective. No offense Vadio, you've really helped, but jut want to see if anyone else agrees with you. I would hate to blow my PS3 or my Apple TV while there. Any suggestions too guys about the Nintendo Wii? I haven't decided if I'm going to bring it as well but I remember reading I think on this forum that because the Wii has one of those power bricks, you have to be more careful. Let me know. But my primary question is about the power strip.
Also not too concerned about region locks. I'm bringing TONS of movies and tv shows and will barely have time (doing a Master's) to watch them all. I don't plan on buying much more than food and laundry lol. I'll wait till I return to Canada to buy anything new.
