For those of you interested in these things, I have just posted current measurements of the Lilliput in various states. It actually has three!!; OFF, Stdy, and SignalLoss. You should be careful assuming that if the VGA signal goes away (ie you turned off your carpc) that the Lilly goes into standby. It doesn't! It is still drawing 214mA! This will eat your battery.
I've also posted pictures of the guts of the Lilly AC-DC adapter.
