Do I Really Need a 12v Television?
I read somewhere on the forum that someone used the inverter to run a regular old TV and it did fine. That got me to thinking that we just might not need a 12v TV for occasional use boondocking. Probably watch a movie and that would be it.
What I don't know is how much using the inverter would affect the 2 6v batteries versus using only a 12v TV? Is there a significant difference in power usage?
Thanks in advance for your input!

Any use of the inverter will cause more drain than use of a 12v appliance. Most tv's now are 12v and you are effectively using twice the power to convert 12v to 120v to operate a 120v appliance that changes 120v back to 12v to operate the tv.

Jim, could this mean that a regular 12V LED TV could be operated by simply powering it with a 12V connector to the power cord? Seems like it.

Yes, read the required input of the tv or the output on the little black converter box, but I just find the right rca plug and plug it in the 12v source. I have done that with radios, tv and weather prognosticators with success. Your computers are also dc...

That depends on what you call "significant". Maybe 10% more power, maybe more than that... depends on the inverter.

Yes, there is more conversion loss, and maybe even double the loss, but it certainly doesn't double the power consumption of the device.
For instance, if the TV needs 100 watts, and it takes 5 watts to convert 120V AC power to the DC needed by the TV, that's 105 watts used. Add an inverter to go from 12V DC to 120V AC before going back again, and with double the conversion loss the total is 110 watts. It's good to avoid the loss, but some perspective is needed.

Yes, if the TV really does have a 12V DC input.

Sure, all electronics run on DC power. If they have an external power supply box (adapter), the power form the box to the device is probably relatively low voltage DC... but it is very often not 12V. That first step - read the specs - is important. And power input connectors are rarely RCA plugs; they are usually coaxial connectors, but they come in many sizes and styles.

And, then there is positive and negative.
I fried a nice short wave radio when I got those reversed.

Good point.
Assuming that the device comes with an adapter and you are setting up a cable to feed 12V DC directly into the place the adapter plugs in, you can use it as a model. Just use a voltmeter to test the output of the adapter (and confirm the voltage), so you know what polarity (and what voltage) needs to appear where on the connector.

We have a 19" that we run off a little 400 watt inverter. We have watched movies and sports on it with little impact on battery life.

We do the same. Had the inverter from years ago so no new expense. I had ETI add a charging outlet right at the tv location and the inverter plugs in right there.

For how little we use the TV, which says 14v on the power port, the 300W Bestek inverter is okay. The other downside, besides using a bit more power, is the inverter, at least ours, has a small fan, so it's not silent.
I was tempted to go with a permanently installed Morningstar 300 watt, which has no fan, but for how little we need one the portable Bestek works.

I forgot to mention we are getting the 1500w Escape-installed, all outlet inverter. But it sounds like it won't drain it too much, which is good. Part of my idea was to also view our GoPro footage on something bigger than our notebook.

Nathan,
In our 21' we have a 22inch Samsung from Costco. We also have the 1500w inverter which we use some. The Samsung uses so little power and it's right next to our only 12v outlet, that another option would be to use a silent handheld inverter that is roughly the size of a baseball and puts out 100 or 110 watts. The Samsung is rated at 3.21 amps, which if my math is correct would be about 40 watts. These little inverters are $15 to $20.
The Samsung needs 14volt power, so I've been hesitant to rig a straight 12v to it and skip the inverter. It comes with its own converter brick.

Thanks Bill and/or Earline! Based upon the feedback and also based upon the fact that If for some reason we started watching it more, we could always get a 12v TV. We never had a TV in the Casita and coped quite nicely, but the configuration of the 5.0 TA is a bit more conducive in setup to have the occasional family movie night. Thanks again for all your insight!!

How about one of these? No fan or wires and compact.

Well we went out and got this TV this week:
http://www.bestbuy.com/site/vizio-24...skuId=4904601#
It is not 12v compatible, but it is 1080p which will be nice for viewing our GoPro and Sony a6000 videos. Thanks again for your input!

Where will you mount that 24" tv in the new 5.0?

With your TV at 24" you may need to shop carefully for an acceptable swing arm wall mount, especially if you want it to fully swing around to all parts of your Escape. We got ours from our friend, Tom Fraser (taFraser) who can give you a brand and model. Although only about $15 on Amazon, I'm not sure how it will work with the 24"

Make sure the mount is strong enough that you can hang clothes from the TV.

Hi Bill. Howdy to Earline, we're missing the rally this year. See you two in 2017?
Re: your tv, I have a Samsung 14v tv and tried plugging it into a 12v socket with a plug I used for a radio. Works fine.
I tried a $20 handheld inverter, works fine when I need it but it really gobbles the power. Hint: if you get one, don't leave it plugged in when not in use.

We're getting the 2016 50 TA cpaharley, and I thing it goes on the right-hand wall in the loft area. We are getting Escapes arm that they are installing. I asked Sarah if a 24" TV would be too large and she said no. It's less than 8lbs, so I'm hoping it will be ok..
