Personal air conditioner buying guide

The first thing you should remember is that a portable air conditioner is unlike normal air conditioners. They do not cool the entire room but are quite capable of keeping your personal space cool.

However, it’s only if you buy the right one for your needs. The wrong choice can end up an unnecessary waste of money. This is why we decided to list out the important factors to consider and choose the best evaporative cooler portable.


Size is very important. Most of the portable air conditioner are small and compact to fit into small spaces for your personal use. It should be easy and portable to carry around.

In addition to the size of the unit itself, you should also check its water tank size. Larger tanks hold more and thus mean you spend less time refilling it. Consequently, even if you have a large reservoir, it uses up the water quickly if used extensively in the most powerful mode.

Nonetheless, the personal air conditioning unit with larger water tank last considerably longer. So check the tank capacity or at least how many liters it consumes in an hour.

Cooling Area

When you speak about the cooling area, it’s the space around you that the air conditioner cools. Different units can cool differently sized areas, based on their power and system.

  • The desktop mini air coolers can generally cool a 10-50 square feet radius or 1-5 square meters.
  • The larger, portable evaporative air coolers, however, can cool larger areas, spanning 40-50 square meters or 400-500 ft. radius.
  • There are even some that can cool to an extent of 950 sq. Ft. radius.

It’s up to you to decide and select based on how much cooling you require. You can find out more about the unit’s cooling capacity in its product description.


 There are some additional features you have to bear in mind while looking for the best portable AC units.

vi. Power supply methods

The battery and USB powered options are better for outdoor use while any of them can be used for indoor use. It’s up to you to decide based on where you will be using the mini fan the most.

vii. Versatility

It is always better to invest in a highly versatile mini air conditioner that can be used throughout the year. You this way don’t have to invest in multiple devices to keep you comfortable through the year.

For example, you don’t need much cooling in winter but it is still useful as a humidifier. It should also preferably work as an air purifier and desk cooling fan.

viii. Design and portability

Don’t forget to check the air conditioning portable design and portability before buying it. It should be small and compact enough to move around and fit into small spaces. Having a portable carrying handle and being lightweight add to the portability.

ix. Noise level

A portable unit is generally noisy because they have motorized fans and compressor systems cooling the air. Some people aren’t irritated by it and consider it to be ‘background noise’. If you won’t be able to sleep with the sound, look for devices with features that minimize the sound.

Examples are sleep mode and a programmable timer. Most portable air conditioners list out their decibel ratings. Take a look at them and compare these noise levels with other appliances to get an idea of its noise levels.

 Different people have different noise tolerances. Carpeting, where you keep the air conditioner, your furniture, and the fan speed also affect its noise levels.


Just like anything you buy, you have to compare costs before buying your portable AC unit. It is generally worth investing in an air conditioner portable because it just cools you without cooling the room.

You, in turn, end up saving on your electricity bills. However, it’s useful only if you don’t need too much cooling, and if it’s for personal use.
