A friend wants a battery-powered TV of about 6" or so screen. Do such things still exist? I haven't been able to find anything sensible so far. Would prefer a shop rather than on line.

Maplin have a few 7"/8" ones that run from car cigarette lighter sockets, if you are not looking for those that have the cells built in.

Maplin for one. Have several small portable sets. You might want to think of the near future and get a widescreen FreeView one, though. But they all tend to be quite expensive compared to what you'd pay for a larger mains one.

Are we talking CRT or LCD Technology?
I would think LCD is more feasible from batteries.

Caravan/camping place is a good bet for external 12V and battery powered things like that.

I have a casio tv with a 55mm screen. Model 770. Was a present from my wife about 15 years ago. I wonder what I could use it for in 4 years time

Tim - caravan outlets, like golf, skiing etc really are not the place to go, they tend to be niche and expensive
Like I said - Argos
or CPC
or Maplin
competitive outlets (although, Maplin seem to be falling out of that category with some of their prices nowadays)

My local Cash Converters / Cash Generator has several similar to this one, so I suspect they have a job lot.

CC/CG one is colour, I think LCD, though.

Thanks, but there won't be a car, so rechargeable cells would be best I think.

Thanks all for the pointers.
Maplin has a couple that have batteries; Amazon's better but I don't know how he feels about buying on line.
I'll see him tomorrow so, if I stay sober for long enough, i'll let him know.

Be aware that they eat batteries. My mother-in-law was terminally ill in hospital, the tv on her ward was faulty and she was immobile, the hospital said that if we bought a new tv they would have to have it tested which would take a week (more than the time she had left) so we bought a battery lcd one to give her something to occupy her, but it chewed through a set of rechargeables in less than an hour and a half. Luckily we had bought a number of spare sets.

The one I have has only provision for alkalines - it won't work with rechargeables as the voltage is too low. So you might have to make up a pack with 10 or more cells. And it eats batteries so I wouldn't want to have to pay for alkalines.

CRT or LCD?
A LCD shouldn't eat batteries much more than (say) a Nintendo or SatNav.

good point - he also has no mains (leccy or water) where he is, so LCD would be better.

What power source does he have? It would make sense to get a set that can utilise that directly or via a convertor. But preferably not:
Gert battery bank > Mains invertor > TV wall wart PSU > TV.
Better to go: Gert battery bank > DC-DC convertor > TV if the gert battery bank isn't the right voltage for the TV.
The backlight in an LCD sucks power at a not disimilar rate to that of a CRT. Backlit LCD's are lower consumption than CRT but not by as much as some people seem to think, 75 to 50% not 10%.

It is an LCD. They are still power hungry. The wall wart provided with it is 1 amp. Even if this is generous - which I doubt - it means alkalines will only last a couple of hours or so.
If it's for use in a residence of some sort the cheapest way would be to run it off a car battery - but don't discharge it more than about half way. Two would be needed - one in use while the other is being charged. They're by far the cheapest method of storing electricity.

He seems to be sorted now, thanks: a colleague gave him a TV that runs fron the ciggy lighter socket. He's going to do a lash-up so that there's a socket on a lead, then, as he works on vehicles, he'll just clip the thing to whatever's in! He dosses in a caravan for 4 or 5 nights at a time to avoid excessive travelling. No 'facilities' but all he needs nearby. The TV's just to keep him amused.
