Don't ask me to explain any of this I just got it from my son-inlaw - I asked him as we go to Florida quite often...he said with regard to your question it all depends on whether you have :
a. Compatible reference levels
b. A switch mode power supply
c. Compatible pin selection
d. A warranty for that country
Hope this helps...
I bought a new camcorder for our Disney trip last year.
All you need to do is get a normal USA travel plug adaptor from Boots or the airport etc for �5 and plug in your camcorder charger as normal.
The only problem you might have is that the current is lower, and your camcorder battery will take longer than normal to re-charge.
I plugged mine in for an hour or two each night when I got back to the room, and it was fine for the next day.
Have fun.
