For all you eleco people. What draws more power running a 12volt tv or running the same tv on 240volt through your inverter or is there no difference.
Cheers

Using the inverter uses more power.

To expand upon Robin's succinct response.
Inverters etc are not 100% efficient ... nothing is for that matter, hence there are losses, so boosting 12V up to 240V via an inverter then dropping back to 12V via a transformer will involve significantly more power than merely running the TV straight off 12V.
The only way around this (and I believe they are working on it) would be to introduce 2 Hiclones into the wiring, one on either side of the inverter. You would then also be able to run the fridge and the boss' hairdryer and a microwave and a kettle and a ........

When they come out there will be a line bigger than at the Apple Store the night before the latest iPhone release

I remember when I was a student back in 1956, my teacher demonstrated what happened when you tried to run an electric motor off a generator connected to the motor, that didn't work either.

The first thing that small TV sets do to the 240 V is to turn it into 12 V to run the set. Why turn your 12 V
battery power to 240 V and then back again?

Sorry i probably didnt explain myself properly,what i meant was why buy a 12volt tv which can be expensive when i can buy a normal 240 volt top of the range tv at alot cheaper price.

Wow, that is a completely different question Humpback, but further to Peter's explaination, there are many 240V TV's that simply have a 240 to 12V plug pack then use 12V into the TV. Buy one of them and you have a 12v TV for a 240V price.

That is cheaper than buying the inverter to run the 240v TV anyway.

12v is king but also remember that to watch free to air you need a Digital TV with inbuilt setop box. Many older 240V TV's needed a separate set top box. Also as for Kogan stuff the build quality is not good, the panels may be Samsung or whoever but the boards are cheap jobs with high percentage of failures.

Digital TVs have digital tuners - no inbuilt set top boxes.

Semantics really they both do the same thing, my point is an older 240v TV will need a set top box , a new TV will have a digital tuner inbuilt.
