Hi everyone,
in a couple of weeks we are heading south with our caravan so we are expecting very cold nights for 6 weeks. We don't normally bother taking a tv but thought this may be ok to have just to watch the odd DVD.....Can anyone tell me do they use alot of
battery power?. The tv is a 17 inch LCD if that info helps. I can't see anywhere on the box that tells us if it is heavy on
battery power.
Thanks in advance
Andrea

If it has a 12V cable expect 5A per hour drain on the battery.
If it is 240V you will need an inverter and then expect about 7A per hour drain on the battery.

Best option is a 12v LCD however you will need to pay for this. As mentioned here it will use less power than having to run and inverter or worse, a generator.

Yes,probably about the same as a tv.
Generally ,if an appliance doesnt need to make heat or spin an electric motor,it wont use much electricity.
There is a very small electric motor in a dvd player
Most appliances have the amp draw in the instruction booklet and you can get a rough idea from the wattage which is usually on the back of the appliance

If you do have to use a generator make certain that it is an inverter type as you will stuff up your LCD television as
well as your laptop and possibly your 12/240 compressor fridge.

If it's just to watch the 'odd DVD' why not just take a portable DVD player or use your laptop (both of these can run on their own batteries for at least the length of a movie)

Thanks to you all for your comments......I will get my husband to install the tv now. We will be using a portable DVD player that runs on it's own battery. The reason for the Tv is that I have trouble seeing the small screen of the DVD player.
So now i will be able to watch the occaisonal movie....
Thanks again.

Whether they draw a lot of power is subjective. A lot depends upon how big the battery is, how quickly it recharges and what the other power draw you have on the battery.
You should be able to find out the current draw of your TV by looking around the back for an information plate or some embossed lettering. Most 12 V TVs I am familiar with draw 3.5 to 4 A. If you have at least a 100 A/H battery and plenty of charging capacity plus no 12 V fridge you should be able to watch a few hours every night or so. Turning off the lights will help with your power budget.
