Best Portable Air Cooler 2021

But you have to consider the cost of installation and maintenance among other factors. A portable air cooler is a small, cheap, yet very efficient way to deliver controlled and concentrated cooling especially in small spaces like your home office, small room, or reading desk.

This is a comprehensive air cooler Malaysia review to assist you through the process of finding the best portable air cooler for you. We have reviewed 6 of the best portable air cooler for your small room and personal spaces.

Differences between Air Cooler & Portable Air Cooler


The main difference between a regular air cooler and a portable air cooler is in their sizes. As the name implies portable air coolers are much smaller.

Mechanism of operation

The principle of operation of both devices is also slightly different. While they both cool the air, an air cooler or air conditioner uses a compressor ( or cooling agent) that extracts heat from the air and pumps cool air into the room. A portable air cooler on the other hand uses only cold water to cool the air and operates based on the principle of evaporation.

Temperature regulation

With an air conditioner, you can set your desired temperature for the room. You can only adjust the fan speed of the ventilation settings of your portable air cooler and nothing more.

Benefits of Portable Air cooler

Concentrated cooling

Portable air coolers cool the air efficiently especially in smaller spaces. A good quality air cooler will be able to reduce the temperature in your small home office, bedroom, sitting room, or even around your reading desk. If you spend a lot of time in just one part of your home, you can use a portable air cooler right there where you are to deliver a much more controlled chill in your immediate environment.


One major advantage of portable air coolers over regular air conditioners is that they are more energy-efficient. This helps you to save costs by reducing energy bills and is also great for the environment.

Can be carried with you wherever you go

The main idea of having a compact air cooler is portability. A portable air cooler can be carried with you and used in any room of your home. This way you don’t have to acclimatize to a new temperature each time you move to a new room in your home. It may even be suitable for outdoor use.


Portable air coolers are generally easier and cheaper to maintain. There are fewer moving parts that can get damaged and faults are generally easier and cheaper to fix.

Things to consider before buying a portable air cooler


You want an air cooler that can perform its intended functions as effectively as possible. Most modern portable air coolers don’t only cool the air. Some double as an air humidifier and may also have help in purifying the air. You should confirm how well your unit will be able to perform these functions. Factors that may affect the functionality of your air cooler include

  • Battery capacity
  • Tank size
  • Air filters
  • Ice plates


Portable coolers are not too expensive to buy and maintain. However, the cost may vary from one unit to the other and how much you are willing to spend may determine the functionality of your air cooler.

Energy Efficient

Although portable air coolers are generally considered to be more energy-efficient than regular-sized air conditioners because they simply pull in and cool warm air, their energy efficiency may vary from one unit to the other. For units with a rechargeable battery, be sure to check how long it will run on a single charge and how fast the air cooler recharges.


To get the best performance from your portable air cooler, you should ensure that it is perfectly sized for your space. Although most air coolers are portable and designed to be desk-sized, a unit that is too small may not perform its intended function effectively.

Noise level

The noise level of your air cooler depends on the model fan speed setting and the overall quality of the appliance. Generally, portable air coolers may emit noise between 30 and 82 decibels. If you are easily distracted or woken up by noise, then going for an ultra-quiet unit is recommended.
