Using a Powerbook in Europe.

Message #1 - Posted 2006/03/08 - Dale Thompson

My husband was the happy recipient of a 12" Powerbook G-4, when our daughter upgraded to a larger screen, newer Powerbook. We are going to France in May and he is wondering what he needs in the way of equipment to be able to use his new favorite while there. 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.

To e-mail me remove the obvious before @ and change sinuswave to sinewave.

Which country are you in at the moment?

My computer runs at 3.5MHz and I'm proud of that "Most importantly, I'm now playing as a girl who skates around in her bra and knickers."

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.)
