This is a 12v and 2 amp supply, just get a car cigarette lighter adaptor onto the end of the leads and you can plug the goto into that, JUST GET THE POLARITY CORRECT + to + and - to -.
Or if you don't want the cigarette plug on the end any more then cut it off and connect the lead directly to the 12v supply. But you might want to keep the cig plug on there incase you go away and not have access to 240v.
