    If that is all you want get a 12-14 volt TV. Some Samsungs are 14 volt

    Look at the power plate on the TV in question. Get an inverter at least 70 per cent of this for TV alone. If you have other devices such as DVD player add it's wattage.
    My guess it would be around 300 watts total for continuous rating of inverter.


    For a modern LCD or LED TV, the power consumption will be well less than that, maybe around 35W or so for moderately sized units. CRT TVs (and doubly so plasma TVs) are power hogs in comparison.

    Incidentally, an LED TV is generally just a LCD TV with LEDs for the backlight rather than cold cathode fluorescent lamps.

    Anything that size will be an LCD panel with either fluorescent or LED backlight.

    OLED displays are much smaller (cell phone or laptop) or much larger (55" +)
  • For our 22" smart tv and an antenna booster I use either my jump pack ( lasts about 5 hrs for this ) or my 140 watt inverter that plugs into a cigarette lighter plug.
  • We'v had a TV that was 12v with a wall wart for a 120v power input. It only needed 12v dc to begin with.

  • I use a 300 watt on my 24" tv. One smaller would work, but the 300 is pretty cheap anyway on eBay.
