There was a thread on here a while back and I can't now find it about these. Anyone know what the outcome was? I need something now as I have done the unthinkable and got a tv. jUST GOT TO FIND OUT HOW IT WORKS.:lol-053:

Hi sorry
think that was me, I ended up buying, eBay - The UK's Online Marketplace
eBay - The UK's Online Marketplace
and a solder yourself, plug, but decided that it was too fiddly for my fat fingers, so settled for the made up lead, gonna cut off the cigar plug and directly wire to the regulator.
all items have arrived and look good, but have luckily had tons of work come in and had probs with car so had to muck about with that instead. hoping to do soon though.

12v4 pin adaptor
If you look at this link they do a 12v regulator but also the adaptor to 4 pin that you say is the socket on your TV the adaptor is about £5

These on Ebay will do 12 Volt Stabiliser / Regulator - a must for anyone who owns a 12v TV!! | eBay
The trouble with the cheaper voltage regulators suggested by Alf1 is that they need a 1.5v headroom, ie. for 12v out you need a min of 13.5v in. The batt won't do that for long.
Also they can get hot so if you are on hookup and your charger is giving say 14.2v you have to loose 2.2v, multiplied by the current drawn eg 4A gives a power dissipated of (Amps x Volts =Power) 2.2 x 4 = 8.8w of heat. if the regulator gets too hot, it shuts down. So a big lump of metal id bolted to the regulator. then ventilation to get rid of the heat.
The 12v to 12v regulators at the top of page work like an inverter, they chop up the battery voltage push it through a transformer and recreate 12v but this time it's well regulated. NB. some of these can carry on giving you 12v out when the battery is getting quite flat. Not good for the batt!!

tThanks everyone for your input but after reading through all the posts I am back to square one.

Basically it is just a transformer.
It introduces power losses just like any other transformer.
I would guess the only reason you may need one, is sensitive equipment that must have 12v. Most equipment will operate on a voltage range the only proviso being the life of some components may be slightly shortened under a higher voltage. I would check the plate on the equipment. It may say input 12-14v DC or you may be able to confirm with the manufacturer that a range of voltages will be OK, because I'm sure they realise when they make these things that the primary supply will be lead acid batteries, and these batteries give out anything other than 12v !
