I bought a 24" LED w/DVD player that weighs under 10 lbs and uses less electricity than a 40w light bulb. It is also 12v DC native with a 120v AC adapter too. I have it hooked up in the bedroom to 12v DC so I don't have to have the inverter on. I was looking at various 32"+ for above the dash, and discovered that most of them are 19v DC native, and thought that getting a 12v DC to 19v DC adapter would probably draw less power than the 120v AC to 19v DC adapter that comes with the TV. A quick Internet search found that many laptops require 19v DC and car adapters can be found for under $10.
