Operates on 110 - 240 AC voltage with supplied adapter- OR -- I used it with just a 12 V dc cord in 12 V socket in van.

 Inputs -  Component / Composite (shared)-2- HDMI, 1-USB, 1 VGA (15 pin computer input) RF (TV Cable input) 1 PC / D VI audio in, 1 headphone out, ++      Also comes with remote control.  Just right for VAN or RV--.

 I used it for desktop monitor, and trip planning using my Microsoft Maps on my computer.  Also in the car with my computer &  Microsoft map programs using the GPS antenna that came with those programs, making for a large moving map display.

On the road traveling, I just stuck a little antenna on the window / roof to pick up local free TV stations for news / weather etc. Keeps back seat drivers quite .

It is pick up in person only - I accept only US Cash for the time being -  No Checks, Stamps, or Omaha Steaks.
