Using a Powerbook in Europe.

I found statements that it automatically adjusts to the 220-240 voltage and assume all he needs is a plug adaptor.

I found statements that it automatically adjusts to the 220-240 voltage and assume all he needs is a plug adaptor. Our daughter also says this. Bur he finds ithard to believe, thinking there must be some need for a transformer of some sort. So I told him I would query you experienced guys and was sure
you could give us a definitive answer on this.

We are neither of us experts and would appreciate any help.

Which country are you in at the moment?

Sorry, should have been specific. We are in USA, so know we will need an adaptor plug.

The Apple power adapter is a switcher supply, It takes in the mains power, converts it to raw DC then feeds that to a switcher circuit to generate the required output voltage. As such the switcher circuit is designed to handle a wide range of DC input (i.e. aprox a 2 to 1 range of US and EU type voltages) with no problems. It's not hard support the wide range since the switcher part of the circuit just varies the duty cycle of it's waveform to handle differing voltages. (There are many ways of handling this but ultimately there is a little chip on in the adapter that has the smarts to control the system to produce the same DC voltage to the laptop.)
