A:Answer 30 to 40 watts
Best option for use in a vehicle. Use a 12 volt power port and skip the inverter. I have this TV and it will work perfectly with just a 12 volt battery. My (4/5 year old) version even has a 110 volt AC to 12 volt DC power supply as stock.
Great results with OTA TV, 100 watt solar panel & 12 volt AGM battery.
If you make your own 12 volt power cord, pay attention to POLARITY. If this is Greek to you, ask a nerd. If you get it wrong, all the smoke in your TV will escape and it is impossible to put it back in. These electronic things need that internal smoke and won’t function without it. Kinda strange? Yeah, the government knows all about this matter and will not endorse the return smoke methods because of the difficulties in collecting the tax associated with smoke. Sound familiar?
