Hi:
I am going on an overseas assignment. I hope to bring labtop with me. Since A/C power is 110V/50Hz in US and Canada, and it is 220V/60Hz in most part of the world, so something needs to be done. I learned there is a thing called 'universal adapter', made for this purpose. But I have one question regarding it,
A transformer can easily transform 220V to 110V, but what about frenquency? I doubt this 'universal adapter' can do that.
But I guess it is ok with me, if it is ok with other people.
Besides this, is there anything else I need to be aware of?
Thanks in advance!
Don

I made a mistake in my first try. So, I will give it a try again.
I don't think the frequency is a major factor for any electical system. When you buy electrical instruments, the electricity usage will be specified in Watts(Power). That is the key.
Say, you have a computer which takes 110V - 4Amps Current, the power consumption is Power (P) = Voltage (V) * Current (Amps).
P = V * I = 110 * 4 = 440watts. Your computer expects 440Watts power. So, when you go to oversees, and if they use 220V, ask any electroics shop keeps to give you a 110V - 440 watts "step down" adapter/transformer.
This is what I was told. I am also curious to know whether what I was told is right or not.
Did you check your laptop? I have seen switchable (110-220V) power supplies for Desktops. See whether you can find such a switch in your laptop.

I had one as standard when I was travelling a lot.
Australia is 240V, 50Hz and I just changed the plug when I went to the USA. Very useful.
The rating on my current converter reads:
Input: 100-240V, 1.5A, 50-60Hz, 98-147VA
I'm guessing it will manage anything in that range (this one is untested)

Thanks a lot! Guys.
It looks like frequency is not a big issue here. Thanks again. I really appreciate it!

As most laptops have external power adapters you probably just need a standard adapter for the part of the world you are going to. The main differences around the world are the 110V abd 240v.
You will benefit from an international plug adapter, thus if you came to the UK you need some wierdly overengineered agricultural plug that could take the weight of a lady elephant heavy with child, but if you go to Australia (which has the same power), you need an adapter for a little sisssy plug that looks like it could be melted by a pen cel battery.
