12 V or 110 TV

My TV also runs on 110vac with a transformer or also known as the power wart. This plugs into the TV as 12vdc. So I also have a cigarette lighter adapter and run the TV on 12 volts. This is just like my laptop; I can run it on 110vac or from the power port on the car at 12volts.

I find 12 volts draws .5amps for the TV. The inverter draws .7amps just idling so why have the inverter and more current draw when the TV runs on 12 volts anyway?

X2, in my case the OEM inverter used to power the OEM 13"/CRT TV and the VHS recorder draws more power than my 24"/Insignia flat screen TV and BluRay Player. I do have to use the inverter for the HDMI splitter that I installed to play BluRays simultaneously on the front and rear TV's.

All three HDMI capable devises came with "wall bricks" and rather than cutting the cords, I made my own power cords. The wall bricks are rated as 12V/5A, DC, those work really well with LED lighting strips up to 16'.

If you have any further questions as to the suitability of using battery power vs 120 VAC, look at the powersource on most entry and mid level rigs. Most have "off brand" TVs that are built for the RV trade and 12volt only.

I bought a couple of surplus bricks from an RV surplus and salvage shop just for LED lighting projects at home.

As an after thought, I have not looked for a large screen TV with a power brick. You may find those harder to locate than the smaller sizes. I looked recently for a BluRay player at BestBuy, and found many of the players, including Sony's with bricks. I will continue to look for a splitter with a brick or using only 12 volt and change over when I do find one.
