Refreshing your journey: 12V air conditioning.

Can you imagine enjoying a cool oasis in your motorhome while exploring new routes in the intense Spanish summer or some other hot country? 12V air conditioning can make this possible.

These compact and efficient devices are the perfect solution to maintain a pleasant climate in your motorhome during your getaways. But ....


12V air conditioners for motorhomes and campervans are systems designed specifically for recreational vehicles. They operate using power from your vehicle's battery, making them ideal for use on the move or when you are parked in places with no electrical connection.

They use compressor technology similar to conventional air conditioners, but adapted to operate efficiently on a 12V power source.

Their proper functioning is, of course, dependent on compliance with technical requirements and proper installation. For optimal operation, it is crucial to ensure that your vehicle's battery is in good condition and capable of supplying the necessary energy. Here it is essential to get advice from the professionals you entrust with the installation of your device, about which batteries are best for your vehicle and what additional equipment will be necessary for proper operation. In addition, proper installation ensures optimal airflow and efficient air conditioning performance. This includes the strategic location of the unit, as well as the correct electrical and drain connection, for which we also recommend professional advice.

At this point, the next question on your mind may be:


These air conditioners are perfect for small to medium sized motorhomes, caravans or camper vans. They are ideal for short trips or for those who prefer mobility and do not wish to rely on external electrical connections. However, in larger vehicles, their cooling capacity may be limited due to their compact size and power capacity. Obviously with 12V power, they will never be able to match conventional air conditioners, which rely on 220V power.


As we have already mentioned, one of the main advantages of 12V air conditioners is that they do not need to be connected to the mains and are energy efficient. In addition, as they do not depend on an external connection, they offer greater freedom of movement.

However, their cooling capacity can be limited compared to traditional air conditioners, which are designed to cool larger spaces and can be more powerful.

They also require a battery with a high energy capacity and the installation of other accessories to ensure their proper functioning and to avoid serious problems with the electrical installation of our beloved vehicles.



At this point, it may be clear to you whether this type of air conditioner is right for you or, on the contrary, all we have achieved is to confuse you even more. So here is our final assessment in case it helps to clarify anything:

In summary, 12V air conditioners for motorhomes and camper vans are an excellent choice for short trips or for those looking for a portable, self-contained solution. However, it is important to consider the size of your vehicle and your cooling needs before making a decision. With proper installation and regular maintenance, these devices can provide you with the comfort you need during your adventures on wheels.
