The air conditioning system in most cars is built-in. Nevertheless, there are a few exceptions. A portable air conditioning unit designed specifically for vehicles can be used if your car does not have one or it is damaged beyond repair.

When Buying a Portable Air Conditioner for a Car, What Should You Look For?

You must know what to look for before buying your first portable air conditioner. Picking a random option would be impossible due to the vast number of options available. Here are a few things you must look out for before buying a portable car air conditioner.

The size of the air conditioner 

A portable air conditioner’s size is perhaps the most notable feature when it comes to portability. There are a variety of sizes and shapes to choose from. Considering how little space you’ll have in your vehicle, make sure you can fit it on the floor or on your seat.

The placement must be safe from sliding around. Measuring the space in your car where you intend to use it is the best way to know what size you need.

Make sure it is not on the dashboard or anywhere it cannot be secured. It is not only dangerous to drive like this, but it can also tip over and spill water everywhere. In order to optimize the airflow, every portable air conditioner requires a few inches of clearance.

The Total Number of fans

Portable air conditioners have small fans inside their front compartments that push cold air outside. You will get more airflow with higher air pressure if you have more fans. Large cars benefit from such models. If you own a compact car, you may also get satisfactory performance from a few fans.

The Water Tank

The portable AC units contain a dedicated water tank for extracting heat from the intake air.  When the water inside the water tank has been used up, it will need to be refilled. If the water tank has a large capacity, you would not have to fill it up too often.

The total battery capacity

A portable air conditioner that uses a built-in battery will be able to run without the help of your car battery if your car battery is not capable. Different products have different battery capacities. Hence, every AC unit will have a different battery backup based on its battery capacity.


Inside a portable air conditioner, there are several tiny parts that work together to complete the air cooling cycle. If the AC is still functioning, its performance will be significantly reduced if any one of these parts is destroyed.

The only way to be certain of the calibre of the components placed in your air conditioner is to choose a dependable alternative that is backed by a manufacturer’s guarantee. If the device has a warranty term, any internal AC parts that become broken on their own will be repaired for free.
