Hi !
My friend just sent me from Japan a C3000. Problem, I am in a 220V country, so I use a universal adaptor to charge my Zaurus.
I used the same I used for my C700: 5V out, 1A 12 VA max, quite the same than the sharp one, except it tooks a 220V input.
Problem: when I connect the adaptor, the charge led don't blink. Why ? Should I wait a moment because it is the first charge of the batery ? Or is it a problem ? The polarity is OK, and the adaptor works well for my C700.
