Probably a stupid question, but how do you power the P1900 in the house? I'm probably going to pick up a 2140 soon and I want to work with it inside while I play with the USB interface. I have an AC -> DC converter that will power small devices, but nothing to simulate battery/Alt power.

And do remember that the P1900 has a timed lockout to prevent starting the mini back up within a period of time after sleep... If you do forget it will appear to you that it is not working, so try to....
I believe it is 60 seconds, and it is after both power on and power off (so if you kill the ignition within 60 seconds, it will stay on for the remainder of the time).
