Anyone know how to power their laptop from canada in UK?

I have an awesome laptop I am going to take to London. I would like it to stay awesome and not fizzle out from overpowering.
Need help, anyone have an Idea of what to do?
would suck to have bought the wrong power converter and lose an expensive laptop

thx

All you need is a plug adaptor so it will fit into the plug in the wall, a laptop like most things gadgety things (camera chargers, mobiles) these days can handle 110 to 220 volts. If you are worried about it and want to see it in writing look along the length of your power cord, if there is a box along the length read what it says on it, it will say the voltage it can handle.
