How do I run a 12V 3A monitor (made for a car) into a home AC outlet?

Go out and buy a 12 Volt 3 Amp power supply. Most of the electronics parts distributors sell these.

A 36W AC adapter will be relatively expensive. I'd use an old PC PSU instead.

I recommend that you get a desktop power supply unit to power the display, such as the ones at MP Jones Associates:

Similar power supplies are available elsewhere, but these are priced right.

Why not use a car battery? Then you can use it when AC isn't available.

I like the price of these - if I can run it right from the monitor to an AC outlet, that would be ideal! So am I right in assuming if the monitor says 12V 3A - then one of these will work with it?

Yes, they'll work just fine.

That is great, that is going to help me out. Thanks again.

That takes me back to my early Amateur Radio days, running my rig off an on-charge 12V car battery on a tray in case of acid spillage! I used to keep the window open in case of hydrogen build up.

A car battery is not something I'd want in my house now, but it would certainly do the job the OP wanted.

Yes, you should be able to use either of the units with your display. You might have to cut the coaxial connector off the cable and wire directly into your display. Just make sure that you have the polarity correct. Measure the voltage on the wires with a voltmeter before you hook it up. Power supply (+) goes to display (+)!!!
