Here's one for the Alpha techies.
In the course of sorting out my I-Book to use on board I purchased a car adaptor from the Apple store.
If I left the battery in the I-Book it would continue to power the computer and not charge. If I removed the battery I could run the I-Book using the adaptor. When I added my extension lead the I-Book would not run at all.
On checking the adaptor closely I noticed that the input voltage was quoted as 13.5 volts. This seems high to me. On my boat with two brand new fully charged batteries I reckon about 12.7-12.8 volts maximum is the best I am going to get.
Any thoughts on this? Is 13.5 volts standard for car adaptors? I'm also going to get a car charger for my Pod with a view to using it on the boat and don't want the same problem.
My Nokia mobile phone charger works fine onboard using the same socket.
I tested adaptor in my car and it works as expected.
