Thanks for the help. Unfortunately I live in Sweden and the adapter that you link doesn't ship here. Even if I found one on american Amazon that ships here it would be quite expensive to ship from the US and pay customs.

As you say it is a generic power adapter. I have found an adapter that I can buy here that has the same contact and supplies the correct voltage (5 V 2 A) with center-positive polarity. The problem is that if the polarity the Fast Track C600 expects is not center-positive, I could destroy it. So if anybody who has a power adapter for the Fast Track C600 could check this I would really appreciate it. (See link in my previous post).
