    Getting a bit off the posts topic, but for 5v and 3.3v-1.5a. http://canada.newark.com/webapp/wcs/...&storeId=10196 This item is the best solution, small, no heat, efficient. SNO

    I bought some of those, and wanted to power a USB hub with one, but my hub wants 2 amps. I wonder if I can put 2 in parallel, or would they fight each other like switching supplies do? I had a glorious fire at a model train show when I setup a12v switching supply in parallel with one my buddy installed several feet away.

    I am being told by Derek now that the cigarette port is fine to power these. As it has a protected circuit. Not sure if my 1970 chevelle has this circuit in it. How could i replicate this circuit?

    I think what he is saying is that if you use the cig lighter adapter its fine as the adapter will regulate the 12v but he might also mean if you hook up wires to the wires going to cig lighter socket it is fused with usually a low amp fuse say around 10amps. But I personally would regulate the power going to the screen. Just my 2 cents SNO

    I think that most cigarette lighters are powered only when the engine is running, where older cars they were always on. So you can use the ignition wire to trigger a standard automotive relay, and run the 12v to the lighter through that relay and back to the lighter to upgrade it if its always on.

    12v 5Amp , so if im running 2 of these screens at 2.5 Amps I should be fine, right?
    comes with a 5v 500mA as well.

    You don't need anything with that regulator, it is all built on that little T-220 board Thats why I love them so much. Here is all you need to do. SNO Name:  minireg.jpg
