What size TV is best for my Caravan or Motorhome?

Caravans and motorhomes may be getting bigger — but they’re still not quite spacious enough for a 50-inch screen. You need to use space efficiently, while still getting a TV that gives you an immersive experience. So what screen size works well in a caravan or a motorhome?

Generally, it’s best to choose a TV no bigger than 32 inches — and this is in larger models. Most caravans and motorhomes are best suited for smart TVs around 19”-24”.

What is the largest 12v TV you can buy?

The Alphatronics SL-Line+ 12v TV , has a 32″ model, which is one of the largest 12v TV’s available on the market.

Can I watch Netflix in my caravan with this 12v TV DVD Combo?

Yes and additional streaming apps such as Amazon Prime Video, BBC iPlayer, Disney+, Now TV, Youtube, itvX and all other major UK streaming app.

Is there a difference between a 12v TV and a normal TV?

Yes there are quite a few. The main one is that it can run off a 12v power supply such as a leisure battery or power bank.

The next is that the TVs are shock and vibration tested, this means that when you are exploring some smaller bumpy roads, you don’t have to worry about it breaking the TV. This is not the case for a home TV as it is unlikely to be receiving vibrations or shocks.

The TVs are climate tested, and are suitable to work at +45 degrees (for Spanish holidays) and -10 degrees (for Scandinavian holidays!).

Can you run a 12v TV off a 12v battery?

Yes you certainly can. All K-Line+ TVs come with a 12v power supply ready to be plugged in.

How long can a 12v battery run a 12v TV?

In short, between 50 and 65 hours.

This table shows how long each of the SLA-LINE+ TVs would work on a fairly common leisure battery that has 70 amp hours:
