another TV size and wattage Q

Hi, Im sure this is answered somewhere else but need to know.

We have a 24 inch '12volt' w/dvd incl in TT. It broke.

Want to upgrade to 32inch w/dvd incl, BUT its not 12v.
dont want to $pend on the Jensen 32/12v.

We regularly camp w/generator, i.e. quiet-time 8pm (primetime watching).

Will this eat the battery too fast? Should I stay smaller 12v?


thx in advance

How many Amp hours is your 12 volt battery? Look at the tv you want and see what the amps per hour rating is. Then do the math to see how long it could last on a full charge.

Should be OK

I have a 120 volt TV about that size in my 27RLS. I run the TV off of a small inverter and it draws about 5 amps from the battery. I also run the entertainment center for the DVD and it uses maybe another amp of current.
Assuming you have 2-12V batteries it should not be an issue. It would probably be OK off of 1-12V battery as long as you do not run the TV too long.

I have a Visio 32" with an energy star rating. It only uses 35 watts and can run for a few hours or so on a group 27 battery (regular battery that came with tt)

energy star rating is worthless, I have seen specs for tv's where same size led without energy star rating use less watts, than one with the rating. you really have to look at the specs to know for sure.

First ditch the tv/dvd idea and get an led tv. They pretty much all drawl very low power and you can run them on a small inverter. Also add a blueray DVD player that you can get a Walmart or similar outlet for as low as $50. They are very small and easy to stow when not using. By going this route, you have a lot more options. This way if the tv or the dvd player goes bad, that's all you have to replace.

You need to step up to a 2 battery setup. The twin 6volts are best, but 2 12V will do. You can run your tv on the gen during generator hours and switch over to the inverter when you shut down the generator. You will be fine with running the tv and dvd player along with lights etc until you go to bed. Next am fire up the generator and recharge the battery while you are preparing breakfast.
