Television - 12 volt or 120?

Bought our trailer new back in 2002. We rarely use the TV, that just isn't the type of camping we do.

That said, wife wants to upgrade (the TV) to something more modern - mainly with the intention of connecting it to a iOS device and streaming something that we have downloaded off Netflix or Amazon Prime. I am already limited by the "box" that was built for the old TV technology, basically limiting me to a 28" TV, but I am also trying to decide on power source.

I just have the standard two 12 volt batteries in the RV. We probably camp with electricity 60% of the time. I have a built in generator, as well as take a Yamaha 2000 if I think I might need to just charge the batteries.

Most trips without electricity are 2-3 days.

I do not have solar, and don't really plan on adding it. I do not have a built in inverter.

Where the TV goes, I have both a 12 volt outlet, as well as a standard 120 AC plug.

My question is, am I better off searching out a TV that will run on the 12 volt outlet, or would I be ok buying a standard TV and using a inverter on the occasions we are using the TV when we don't have shore power?

There are a lot more options (and they are about half price) if I stay with a standard AC television.

  • More choices and lower prices for a 120 Volt TV. Couple the TV with a small PSW inverter, you are set. My combo uses less than 5 AHs...28 inch TV, booster and inverter.
  • Modern TVs don't use a lot of power. A small inverter would be a perfectly fine way to go; it won't run down your battery overly quickly. That also makes it easier to hook up e.g. a blu-ray player or game system or satellite receiver if you wish to do so in the future. (It's perhaps worth mentioning that many of the newer game consoles use more power than you might at first suspect, often roughly around 100 watts, more than many television sets.)

    Of course, if your television happens to have an external 12V power brick, it does make a lot of sense to power it directly.
  • Many TVs now have a power brick that converts 120 volts to 12 volts. If you get one of these you might have better efficiency as opposed to running an inverter. The TVs marketed for RVs are usually low quality at a high price. While shopping, compare the wattage of those that might fit your needs.
