14 volt, 2.5 amp TV hookup?

[WalkaboutTed]

We plan on traveling indefinitely and do not want to feel deprived. So, given the fact that Sweetie Pie likes to vegetate in front of  TV for all of an hour or so some evenings (if I'm lucky, he starts sawing logs in 10 minutes and the TV is turned off), we've decided to go ahead and install one.  I found at Costco, a Samsung 24 inch LED TV/monitor with an input of 1.0 amp at 100-240V@50-60Hz.  The output is the above, 14.0 volts, 2.5 amps.  I can also use  the monitor for my photo editing, much better than my dinky laptop.

My question is, since the TV is 14 volts DC, how can I hook up directly to a 12 volt outlet (assuming that I can), and skip the inverter?  Inquiring minds want to know. Of course, this is providing that we have enough juice.

Thank you much already,
Ted

You will need to hook 12 volts from battery through a fuse to this device, and have a wire with appropriate connector to plug into the TV.

An issue will/might arise when charging the batteries when the charging voltages exceed 14 volts.

Generally a 12 volt device will work from 10.5 volts to 14 volts.  It need not be exact, on most devices. 

Your 14V tv will likely work from 12 to 16v without issue. it might even run without a voltage booster to take 12,8 battery voltage snd stepping it upto 14v.

 There are exceptions.  I do not know if your TV is an Exception.

You can also choose to run TV on an inverter and accept thae 10 to 15 watts more that this will consume over a direct DC to DC adapter.

inverters are known to be electricaly noisy.  If using an antenna to pull in over the air TV stations, the inverter can knock out some weaker stations, and even some stronger ones.  Depends on the frequency.

But so Can the DC to DC converter.

My Dc to DC laptop adapter knocks out my channel 8 and 10( actual)  which are my strongest TV stations, but it does not interfere with some other weaker stations that are broadcast in the UHF spectrum.

I will be making a Faraday cage for it, adding capacitors to the leads and ferrite cores over the wires in an attempt to reduce the interference.  At some point.  For now, closing the laptop is the cure.

The samsung TVs failures are usually power supply related, so if you choose simply to use an inverter and accept the wasted electricity suing one, you should use a Pure sine wave inverter, unless you are looking for a reason to upgrade the TV, then use a small dedicated  MSW inverter just for it.

Assuming this TV/monitor uses a wall wart for power, with the DC input jack on the device, you might find a 14VDC adapter to plug into a standard 12VDC car socket ("ciggy plug"). I have this for my laptop, that allows me to use the van's 12VDC converted to the 19VDC that the computer needs. Check on Amazon.

Personally I would find the same tip that is on that adapter and wire it direct to the the 12 volt supply, plug it in and check it out.. Tips are available on line or at Radio shack etc.
