Hi I have bought a 15inch lcd tv and need a 12v car adapter to run the tv in my caravan on 12v. Could anyone on here advise on which adapter i would need to purchace. On the AC adapter it says on the back INPUT 100-240v 50/60hz 1.5a OUTPUT 12v=5.0a and on the back of the tv it says DC 12v / 50w Hope someone can help and give me a idea.
You simply connect the 12v 'van supply to the 12v input on the back of the TV.
Generally I would also suggest that you should use a voltage stabiliser because the battery voltage will vary so much. However many don't and and in most cases there isn't a problem
Most caravan spares suppliers sell conversion leads to convert from the 12v, 2 flat pin socket in the van to a car cigar lighter type socket but is this the type you need?
Is the tv just a normal LCD that only has a 240v lead but you want a lead to be able to run it on 12v? Or am I being thick (wouldn't surprise me lol )
We have a small LCD tv which we would like to take away with us but have the problem where we need another lead, or something, to be able to run from a battery. Or would this be solved better with an invertor thingymabob (very technical sorry!)

Hi
No your not being thick ypu have hit the nail on the head the tv has got a 240v cable going in to a transformer and this then takes it down to 12v so what i now need is a cable with a cigarette socket on one end and the round socket on the other but im not sure where to buy or which to buy i have looked on ebay but there is so many different types.

Got it in one: Use a stabiliser because the output from your battery, at rest-engine not running, could be as much as 13.7volts. This will not do your TVs little circuits any good at all
Make sure that the power is going thru a voltage stabiliser first otherwise this all going to end in tears
As you already have a 240Vac to 12Vdc transformer, you actually already have a 12Vdc TV. The bad news is that the !"Vdc supply in a caravan can vary quite a bit which will shorten the life of an LCD TV.
May I suggest that you use a device that takes in an unregulated supply and outputs a regulated supply to your TV.
Something like [url=http://www.amperordirect.co.uk/products/VersaPower70xs.asp] this link [/url]
For other appliances that only have a 240Vac mains cable connected directly to the appliance then you need a 240Vac to 12Vdc invertor. This is much less efficient and can put a considerable drain on your battery.
Just take the 12V directly from your leisure battery. Observe the polarity, double and triple check it before connecting your TV and it'll work fine. 13.7V is unlikely to upset the TV's 'circuits' simply because the TV will have its own onboard regulator. The plug in transformer you have won't be slap bang on 12V either.
Take the 12V transformewr to Maplin. Explain to the pimply anorak behind the counter what you need. They sell loads of different plugs & sockets & will certainly have what you need. You may need to do a bit of DIY soldering to fit the plug needed. I have used this method to wire up the 12V lights in my trailer tent.
