Overview of 12v TV DVD Combo – SLA-LINE+ Smart TV

This 12v TV DVD Combo SLA-LINE+ is a premium Alphatronics model with an already integrated DVD player and soundbar providing outstanding sound & image quality, whilst only using the very minimal amount of power necessary. The focus of this model generation is LG’s new WebOS TV operating system. Thanks to direct access buttons for the streaming providers “Netflix” and “Amazon Prime Video” and the practical voice control and air mouse function, the user experience is simplified and even more intuitive.

A special feature of the SLA-LINE+ is the outstanding sound quality. The integrated sound bar with front-firing speakers offers an optimal sound image, specially adapted to the conditions in the vehicle. In addition, it comes complete with an integrated DVD player. This 12v TV DVD Combo includes all the most popular streaming apps like Netflix, Amazon Prime Video, BBC iPlayer, Disney+, and more. Since the classic DVD is still an important playback source, the SL-Line+ has a built-in DVD player. This can be easily and conveniently controlled via an additional remote control.

This SLA-LINE+ 12v TV DVD Combo is ideal for campers, caravans and smaller motorhomes. Available in 3 sizes: 22″, 24″, 27″.

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:

Watts Usage151821
Equivalent in Amps on a 12v Battery1.251.51.75

Do I need a TV bracket for my Motorhome or Caravan 12v TV?

It’s recommended as you can have a large amount of freedom in positioning the TV. Our motorhome and caravan TV bracket for example has 3 arms interlocking arms giving you the choice to have your TV close to the wall or extended far outwards.

Our M7441 can be adjusted to have 3 connecting arms or 0.

Do I need WiFi for my Caravan and Motorhome Smart TV?

If you wish to watch Netflix and other streaming apps then you will need a WiFi connection. All of our WiFi systems are compatible with the K-Line+ range.

We would recommend the Roam X system for maximum streaming ability across the country.

If you’re not sure which one is most appropriate for you, answer a few questions on our WiFi selector to help you decide.

Do you need a TV license for a Motorhome or Caravan?

If you are planning to watch any of the main channels which fall under the TV license then you’ll need a TV license. This also applies for streaming BBC iPlayer.

If you are living in your vehicle and watching those channels and they are also being watched at your home address, where the TV license is registered, you’ll need a second license.

Despite the vague wording on the TV licensing website, you don’t need a TV license to watch separate streaming services such as Netflix, Amazon Prime Video, Disney+ and so on.

Do I need a Satellite System with this 12v TV DVD Combo?

All K-Line+ models have a satellite tuner built into them so if you have a Sky™ or SkyQ™ subscription or wish to watch Freesat™ then you will need a satellite dish of some kind.

We have portable systems which require a manual setup and automatic systems which are usually roof-mounted onto you vehicle and have a very quick automatic set up by pressing 1 button.

If you’re not sure, answer a few questions on our Satellite selector to help you decide.

Do I need a TV Aerial with this 12v Smart TV?

If you want to watch terrestrial TV, such as BBC1, BBC2 and so on, then yes you will need a terrestrial TV aerial.

Our tried and tested Gazelle Pro aerial will be more than suitable, it’s omnidirectional so no setup needed.
