TV - 12V or 110v with Converter?

In a trailer going from DC to AC and then in the TV back from AC to DC is a lot of waste. If you are only using the trailer on the weekends or only when plugged into AC, there is no issue. If you are boonbocking and using the batteries, then the 12v TV makes a lot more sense.

They lose between 15% to 20%. When you consider that many of these are less than 50W, it's not really an issue unless you run your TV more than 8 hours.

The TVs internally are not all 12V inside either many are 20V inside and why you won't find a separate power brick on the outside. To me, I would rather just buy the TV I want than go through the trouble of finding a 12V TV.

^^^^^^
Ditto. More selection, easier to find a replacement if 12 V poops out, and you don't need more than a small inverter. 300 Watt TSW's sell for $40-$50 and that is often less than the difference in price between a 120 Vac powered TV and a 12 V DC powered one.

How a powerful a converter would a guy need to run a 32" flat screen TV ???

Look at the specs of your TV.

Less than 100 watts. Go get a cheap 300 watt inverter and plug it into the current connection for the 12 volt TV. even a 32 inch TV draws very little. Here are some on Amazon https://www.amazon.com/s?k=300+watt+...f=nb_sb_noss_2

I own the smallest one off the shelf at wmt, just plug in my dash and watch sat tv with my antenna and receiver, and also a fan to keep me cool - as well as charge my phone

prob $20

hardwire is better anyway, cigarette lighter connections just don't have enough amperage. 300 watts would be 25 amps and there is often too much voltage drop and the inverter complains. You could use an MSW but PSW is not that much more expensive and better for everything.

I have a 75W one and I like it cause it has no fan. Stays plugged all the time, with the tv, even on shore power. My 2k inverter can stay off most of the time then since it's on-current is higher than the tv, by far.

I run my 32" Vizio on a 150w inverter, on a single Group 27 marine battery.
Will go to dual 6v golf cart batteries when the 27 dies.
I prefer the much cheaper 110v AC tv purchase vs a 12v DC one. Plus the inverter can charge electronic devices, since my 2016 TT doesn't have USB ports.

My 32" VIZIO is rated at 25.5 Watts.

32" Samsung and direct tv receiver on a 120 watt samlex pure sine wave inverter. Plug in to the ant. booster outlet. The 12 volt outlet on most ant. boosters are fused at 15 amps so you would have to keep your load below 175 watts. My tv draws 30 watts and the receiver about 75. The fan in the inverter has never come on although I have only had to use it a couple times in National Parks.

I would have no idea how to hard wire one,,, guess I will look around for some info !!!
I wood love to have some sort of plug in,,, so I can run TV on 120V when we have Power

So after much research, I think I'll pony up for the Jensen 32" 12vDC TV. I feel like it is built for the incredible bumping and grinding of on the road travel. And as much as I'd like to support an independent e-tailer like ETrailer.com who offers it, they don't offer any type of extended warranted insurance so I'm going to have to buy through Walmart who partners with Allstate on these.

Would love any additional input if I'm missing something here before shucking down $350+ bucks on this replacement unit. (Doesn't look like they are making the 32" Insignia 12v DC TV that pooped out after about 16 months of use.)

If you actually think Jensen makes their own panels, you would be mistaken. They are bought from a panel maker like many of the 2nd tier TVs do and they are not made any more rugged.

I'm sure you have researched this product fully but this website I found appeared to provide some rationale for thinking this product might be a bit heavier duty than some others.

Not sure if this helps ya. When I installed a 12v tv I went to Walmart and looked at their working display models that interested me. I then went behind the tvs and looked at the plug in adaptor and read the output on the label on the adaptor. For eg 120v input ac..12v output dc. Found the one suitable and also found another male input that also plugged into back of tv. Hardwired this input into 12v system of trailer. Kept adaptor intact so that tv could also be used with 110v.

The panel is no different than any other brand. If you want to believe their marketing about the cabinet being heavier, go for it. they do NOT make the panel...the part that would be likely to break. I have an engineer friend that works for a worldwide panel manufacturer. He may be wrong but I kinda doubt it.

No disagreement on the panel sourcing but there's just not a lot to choose from when you have a specific size (32") and really prefer getting another 12v DC powered unit. Being from Kalifornia, at least you're not saying this unit causes cancer...thx for your input!

I would be one of the few people from Kalifornia that wouldn't say that...hence the way I spell it that way.
