I would take my TV cord with Brick with me to Radio Shack... If it is around 15-19VDC output from the brick it will most likely work just fine on the TRAILER 12.6 thru 14.4VDC DC charging outputs.
I have one 15-inch TV that has the 120VAC-17VDC brick and it works great off the trailer DC circuit with the proper connector I picked up from Radio Shack.
I also use a 600WATT Pure Sine Wave Inverter that powers up all kinds things like TV's, DVD player, cellphone chargers, computer chargers, small fan, desklamp, etc.. Being PURE SINE WAVE I can plug anything 120VAC into it and not worry about BLUE SMOKE coming form it. I ran two drop cords from this inverter using wiremold cable kits to hide the extension cords with one going to the home entertainment cent location and the other one going to the bedroom night stand. Momabear has even used her electric lap blanket heater with it.
This INVERTER is on 24/7 when using the trailer.
A great PLAN-B item for us...
