Your "Jenson" is a cheap garbage TV brand, as such if you think it is good quality you are sadly mistaken.. It is the typical junk that everyone who owns a RV whines about poor quality. And, when your Jenson dies, you will have to search hi and low online and pay a premium price for another same junker as absolutely no retail store carries them.
You're obviously very, very unhappy that we're happy with our 12v Jensen TV. Duly noted ๐

I am guessing you were fine with the quality of "VHS"? I wasn't, preferred the pix quality of Beta tapes and jumped on Hi8 units when Sony came out with Prosumer units with tuners (yeah I was spoiled by working in an industrial video setting as my first job which included broadcast 1" Sony video recorders with TBC, Grass Valley editing equipment and broadcast quality cameras, so I know the difference in video quality).
I will gladly use a few watts more of energy to trade for a TV which has better tuner, better picture and better life and when mine dies is very easy to locate a low cost replacement at any retailer..
One or two Ahrs of battery per day is not going to make you run a gen longer or spoil your non gen long weekend.
The obsession of how some folks pick their energy battles makes me chuckle.. Personally if battery consumption is such a problem, then rethink the TV thing as it is a waste of energy with the lame programs foisted on us now days..

Additionally, folks often do not realize with the TVs with an external 12V power supply that those TVs are designed for COMPUTER "12V" (11.9V-12.1V) and never were designed or intended to operate from a 12V BATTERY which can have voltages from 10.5V up to 15V..
Honestly, running a TV from a inverter is not going to kill you, not going to use a lot more of the battery and are cheap and plentiful to find and buy and you WILL get far better TV than the ones marketed as 12V..
The loss on 12 volts to 120 volts and back to 12 volts is typically about 30%.
I bought a 12 volt laptop adapter that converts 10 - 24 volts and stabilizes it to 12 volts regardless of input voltage or (within reason) draw.
The cost was $29 and the loss is well under 5%, win, win.
No, the loss is typically under 8% per conversion or about 16%.
On a TV that draws say 100W we are talking 16W of loss, 16W is roughly 1.2A at 12V and that is peanuts to be quibbling about unless you are running that TV 24/7.
1.2Ahr is nothing to get your panties in a wad about, your PC wastes much more energy than that just typing up your response.

One thing to consider is how much power it sucks. With batteries we talk about amp horus and the USABLE power can be as low as 25% of the battery's C/20 rating (IE 25 amp horus for most Group 27/29 size) or as high as 50% for True Deep cycle (like over 100 amp hours for a pair of GC-2 Or nearly 100% for LiFePo4.
If the TV draws 100watts that's about 1 amp at 120 volt and about 10 at 12 volt. so 100 amp hours of battery would run it about 2 horus.

Most TVs marketed as "12V" are junk brands like Jenson, Furrion just to name a couple and are not built with any sort of real quality.
In the past there were a number of better name brands like LG, Samsung, Hitachi, Sony, Vizio, Toshiba and so on which used an external power supply brick which happened to be "12V". Those are very few and far between now days as most manufacturers eventually went to INTERNAL power supplies..
Even IF you could find one of those TVs with a external 12V brick, they were typically limited in size, often only the SMALL TVs of 19" or less which are pretty much impossible to find now days for sale.. Most stores stock 40 plus inch TVs now days and if you want smaller than that you will have to dig around Amazon and order it.
Additionally, folks often do not realize with the TVs with an external 12V power supply that those TVs are designed for COMPUTER "12V" (11.9V-12.1V) and never were designed or intended to operate from a 12V BATTERY which can have voltages from 10.5V up to 15V..
Honestly, running a TV from a inverter is not going to kill you, not going to use a lot more of the battery and are cheap and plentiful to find and buy and you WILL get far better TV than the ones marketed as 12V..
However . . . I'll say this. A 12v Jensen TV came with our camper new. Been using it for 3 year now. Works great. Very light, very low current draw and no inverter needed. A friend purchased a new 75" Samsung from Costco a few months ago. 15-20 dead pixels, then it died a week later.
My hope is RV manufacturers will push harder for more 12v appliances in the future. Some off-road van manufacturers are starting to use 12v a/c units. Significantly quieter and much more efficient. Throw a 12v microwave into the mix and we'd be awful close to an inverter free camper.
