Beware of high voltage!
Talk about hot, try running in 240v like Australia. You could fry an egg on my adapter.
In fact, I had to switch to a Targus (universal) adapter, purchased in Australia, because I burned out three, yes three, Kensington (universal) adapters down there. Kensington did replace them under warranty, but obviously they were not designed for that voltage, even though it said so.
Voltage is always stated with a variance, because due to power distribution requirements, it will vary during the day. For instance, in Austrailia it is 240v plus or minus 9%, which means it can rise as high as 261. If you happen to be using it at the time, boom! (off to the Targus store)
Even in Europe, it is 230 plus 6%, or minus 10%, making it between 207 and 244, which is higher than the usual rating.
