A lot of the televisions in caravans are connected from the 240v mains via a transformer which supplies 12v DC to the tele.  The trouble is that caravan voltage fluctuates and this can cause problems with teles that are designed to run with a constant 12v.  You can buy rectifiers to eliminate this or get an inverter which turns 12v  DC into 240v AC.

Some teles such as avtex are designed to be run from mains or caravan 12 DC supply.  But of course they are much dearer.

Get an Avtex and hang the expense!!!!!

If your going to use an inverter 12v-240v to run a mains TV without hook up, this will drain your battery a lot quicker.

The inverter will be using more power to turn 12v DC to 240v AC.

Koogan for me, with USB stick full of movies, when signal quality is poor.

Maplins for a 12v supply lead £5.

We rely on solar power for van battery, so the less power we use the better.

If you go onto the Kogan site and dial in 12volt Tvs - these will be true 12volt TV.s and you will be surprised at the price a hell opf a lot cheaper than Avtex

Most smaller TVs run on 12v and have a transformer to convert 240v to 12v.  The only problem might be that caravans don't supply 'true 12v'.  It varies with battery charge and needs a stabiliser to regulate power.  See this article.

They may work but its a gamble.  If they are cheap enough then worth the risk.
