Hmm, now you've got me thinking.
Since the TV is designed as a 12v model that can run off a cigarette adapter I assumed its internal power supply would allow it to run on a range of voltages (say 11 to 14 volts) the way a laptop's will.
The TV is sold for trucks, RVs and boats.

“The sail, the play of its pulse so like our own lives: so thin and yet so full of life, so noiseless when it labors hardest, so noisy and impatient when least effective." - Henry David Thoreau
