Hello again.
I've already examined that page - thanks for the link anyway.
I was really desperate for a charger. And so though I wanted a USB cable (for data exchange), I decided to simply find an alternate transformer (adapter) and add it to the respective pinouts on this cord.

So - I've got something going.
Prob now is, after a while I get the error "charging error, stop charging now".

Voltage/current is too low I deduced.
My new question :D :
whats the correct voltage/current output of a SE ORIGINAL (not fast travel) charger?
