12v tv vs 240v with an inverter?

was wondering which id be better of going with? either a 12v cello tv which states it uses 38 watts or going for a normal mains Tv which states it uses 22 watts. how much extra power would a 1000w inverter add to the mix? my inverter is typically switched on anyway if im uing the tv for the sky box. Also if its needed information i have x4 115ah leisure batteries and x2 120w solar panels on the roof.

my current tv is a 12v cello but the sound from it is terrible so im looking for a change. just dont know what to go with

i use a bluetooth speaker at the min. so been using that method for a while now. im in the mood for an upgrade this year in quality and size anyway

I have a

Cant be a bad thing can it
I'd a few problems last year with power so I've added another solar panel this year along with 2 more batterys.

I have a 12v cello too. I expected the sound to be awful so I just use an external speaker with its own internal power supply. It can be recharged off the leisure batteries using usb.

The future is a smart tv with internet streaming.
Maybe, now is the time to invest into this technology.
Personally I am only waiting for our tv or ariel to kicked the bucket.

I’m just going to get a lightning to HDMI lead so I can stream downloaded or live stream TV/Netflix to my Cello TV from my iPhone or iPad. I use Chromecasts to stream wirelessly at home but it needs my WiFI router to work. The proper apple connector is very expensive at about £50 but cheaper than a smart TV that would still need to tether to your phone or MIFI or use its own data subscription. I don’t watch enough TV in the van to justify it yet so I just use a cheap Freeview aerial or use movies on a big USB powered hard drive.

As pointed out in a previous post, a TV can be made work off 12 volts without be a “12 volt TV”. If it has an external power supply, that provides DC power in or around 12 volts, then you can bypass the external power supply altogether and power off your leisure battery.

My ‘mains’ TV is powered off an external p.s.u/ power brick. So it is actually a DC powered TV. The brick provides about 14 volts. That’s close enough to my 12 volts system to work, which really is about 12.6 volts at night, 14.7 volts during sunny days ( thanks solar energy!). All I had to do was find a matching jack connector to work with my TV. Had I not, I would have butchered my power brick cable, luckily I didn’t have to.

So yeah, there is no need to go with an expensive “12 Volt TV” that markets itself as so, for the caravan market and charges a premium. Most modern LCD TVs will run on 12 volts. But if you’re looking for one Just be sure not to get one that is directly powered by a figure of eight mains power chord. Otherwise, if you’re powering off an inverter, than it doesn’t matter.

My Cello was only about £100 from memory and I move it into the house during the winter for use in a Spare room. They seem a little more expensive now. I had another similar sized non 12v tv for the kitchen already (different brand) and the sound was awful so I just assume it is par for the course for those cheap small lcd TVs. Are pair of £10 usb powered speakers sorted the kitchen tv. I used a self powered speaker for the Motorhome one as I wanted the USB port on the TV to be kept free for attaching an external USB hard drive.

I have a Waeco/Dometic 300 Watt inverter which I considered to be good. I also have a cheap 2500 Watt inverter for hairdyer etc.

Last weekend I tried both to charge my e-bike battery, both failed. I used another Craic'ers Pure Sine Wave inverter and it worked perfectly.

Big difference.

Depends what you want to run, sorry I jumped into the topic.

I have a feeling I know who your late Father in Law was.

One of the things about quasi sine wave inverters is that anything with an electric motor will not run properly but they make no difference to stuff producing heat.
Using one for a hairdryer is ok but with the heat being 100% and the fan running a bit slow the hair dryer can overheat. Sophisticated chargers don't like quasi units at all.

Regarding tv's, those with an external transformer from 230v to 12v it is often not advisable to chop the transformer and make a direct connection to the 12v supply. The output from the transformer is usually a stabilised 12v and tv may not like the variation between 11.8v and 14.4v which occurs in the 12v system when the battery is running down and when it is on charge. For those wanting a 12v supply to a tv with an external transformer one of these is the best job

I have the 2000W Pure Sine Wave version of this one. Got it on Gumtree for £200.
Very pleased with it.
Wife boils the kettle on it every hour plus the microwave an odd time and the odd blast of the hair drier.
Have 2 x 110 watt leisure batteries fed by 2 x 100W solar panel's and MPPT controller.
