22" VIZIO LED HDTV with 12VDC-in on sale

If anyone is looking for a flatscreen that will run on 12v.........I just noticed this on sale at Newegg. I ordered one because the owners manual specifies power as "12V/4.6A from AC/DC adapter".

Vizio 22" Class (21.5" Diag.) 1080p 60Hz LED-LCD HDTV


Specifications here.


$139.00, free shipping.

While this one doesn't run on 12V, I just bought this one (Vizio E261VA):
VIZIO 26

Its 26 inch LED, rated at 32 watts, and and individual at RV net tested it at about 22 watts under certain conditions (dim ambient light).

I know the inverter probably has a 15 to 20% overhead, but this isn't bad for 26 inches, even with inverter loss. The TV works great, nice picture.

Way, that TV runs on 120-240 v AC and uses a transformer to reduce voltage to 12 v. Whether you can plug a 12 v. cable into it from the trailer 12 v. receptacle is not clear. If this were a 12 v. TV I think it would say so because that is a selling point, especially if it can work either way. Amazon also does not sell it as a 12 v.

It is a good deal though note it is refurbished. By whom?

There are small inverters available to provide 120 v. from a 12 v. receptacle. Camping World had one for about $55.

small modification

Yes Gene but a small mod takes care of it. It comes with a power "brick" that is 110v AC in, 12vdc out.

I have made other 12v electronics like our router work by cutting and putting a quick disconnect on the 12vdc output wires of the brick. I then have the same female quick disconnect on a 12vdc supply from the trailer. A cigarette lighter style quick disconnect will work too.

So the 12v lead for the brick can plug back into the brick or into the trailer 12vdc.That way I can run it off 110v AC, or 12vdc when running on batteries only.

Another way to do it is to leave the brick alone and just find a 12v female connector that matches the male recessed receptacle on the TV and spice it into a 12v supply.

THe inverters lose a lot in the conversion so when I see stuff that runs on a 12v brick I'll buy it

Now I see what you are up to. When the TV says 12 volts in, and the batteries are providing more than 13, any problems there? I assume a TV for a "12 volt" circuit is made for more than 12 v., but is this TV ok with that?

I've not had any problems so far (router, TV, weather radio, alarm clock). I'd not do it with sensitive equipment that requires regulated power. The bricks on consumer electronics usually are usually not regulated very well anyway, and any decent set should have internal voltage protection.

( note my use of "so far" and "should" )

I like what your doing with the TV and power supply. In my day job I often run equipment (computers, chemical analyzes, etc.) by "bypassing the brick". It works out great when you can find the right plug for the device and make a clean patch cable. We use Honda 1000 generators and run equipment direct off of the 12v output. This works great as now I'm not using 120v AC and don't have to get real electricians involved.

A couple things worth mentioning is 1) to make sure to have the circuit protected with a fuse either at the distribution panel or in-line on the patch cable, and 2) voltage drops in 12/24 volt systems can significantly reduce power. There are lots of resources on 12v systems, here's one that I've used in the past.

Also West Marine Master Catalog has good chart that gives minimum wire size versus length.

Thanks for the thread on the TV!

I have been searching for a "cigarette lighter" plug that will fit the wall recepticle (12 volt) next to refrigerator on my 19' Intl. It is smaller in diameter than the 12 volt outlet near the radio up front. No luck at Radio Shack or Fry's. Any ideas?

I've been running mine for almost two years now without a problem.

Way,
Great post for the TV, been looking for awhile. Good price too. Thanks!
12v Outlet near the tv (winegard) is smaller than normal, but plan to replace this with a SeaDog 12v outlet with cover to match others I've installed in our unit. I'm installing a Signal Meter to replace the original plat anyway.
Again, thanks for the post and ideas along the thread...

Thanks Wayward...

I had almost ordered some off brand in the same size for $200.. just because it said 12v.
This will work perfect.

I looked up Newegg, the vendor, using "Newegg reviews" and came up with a lot of negative stuff. Among other things, a lot of disgruntled employees also. Google and read. This one: PardonMyFrench: Is Newegg.com Running A Scam? Who Knows But Their Security Is Weak is interesting and somewhat strange after you read—lots of people who have never heard of Newegg suddenly getting charges and sometimes products.

I was about to order the TV, but too much smoke about the company. I also thought is was strange they had so many refurbished models of this TV.

I hope it works for the rest of you, but I don't want to take a chance.

I have been buying computers and peripherals from NewEgg for our home and business for many years. Never a single problem and their return policy is excellent.

We'll see on this set when it arirves.

Glad to hear that. The number of negative comments is daunting to me, however.

I'll keep looking for a bedroom TV and will try to find one with a 12 v. input, so thanks on that part of this. A 2nd TV in a trailer about 22' long inside is kind of overdoing it, so I'm only partly motivated.
