Inverter size (1 Viewer)

[surfbum]

Hi

I have a small avtex 15 inch tv that i like very much .it has a good picture and the sound with speakers in the front is perfect.Up to now ihave allways used it on mains electric on hookup,but over the weekend we stayed in a carpark over night in north Wales, so used the 12v plug that came with it. The red on light came on but i failed to get it to go with remote or manually so assume the 12v is faulty'

My question is .What size inverter would do?. I would also like to charge my laptop as well from it. I thought possibly a 350 watt should be enough .Any help would greatfully accepted.

Cheers Keith.

They are so cheap now I finding it difficult to recommend one.
I have paid £200 in the past for quality 2Kw inverters.

This one is only £36!
You'll also need an isolator from battery.

You are probably only talking about a 300 watt one. I use a 300 watt one for all my needs. Remember you cannot use it for hair dryers microwaves heaters kettles and all that stuff. If you do wish to power other items like them you will have to get a much bigger one. Think about your leasure batteries if you go down this rout. Solar panels are a great idea so make sure you have some.

If the red light on the TV came on then it should work. However, if it isn't I wonder if the voltage is too low? Have you a voltmeter? The voltage should be over 12 but if it is much less then this suggests the leisure battery or batteries need replacing, assuming they are fully charged. Alternatively, you might have the wrong polarity in the 12 volts supply but this seems unlikely and the red light might not come on if it's an led.

Yes it was just to power the telly realy. I assume it will work on inverter just as it does on mains.

Any idea what voltage would read before telly wont work? 12.1v?.

It should certainly work on that.

I doubt the 12v function is faulty as the tv IS 12vac.
It may plug directly into a 230vac socket but has an inbuilt 230v to 12v transformer.
Plugging into a 12v supply simply bypasses the transformer.

I second DBK......the voltage is too low whether it's the battery or resistance in the 12v lead, ie: poor connection etc.

typo John.. 12v DC
