How to choose a portable mini air conditioner?

Cooling Area:

Ensure that you are buying a portable air conditioner with enough power to cool the desired space. Desktop mini coolers can cool an area of 1 to 5 square meters. However, sizable evaporative air conditioners can cover 40-50 square meters. 

Wi-Fi Connectivity:

Having a Wi-Fi connectivity feature in your mini air conditioner can be handy. You can turn off your air conditioner from anywhere if you have forgotten to turn off the device in a hurry. So, it’s always a good idea to choose the one with connectivity features. You can control such portable air conditioners with your mobile phones.

LED Colors Lighting:

Different LED colors allow you to know the current working function of an air conditioner. Some air conditioners also feature ambient colors and serve as lamps when it is dark. 

Water Level Indicator: 

This is also an essential feature as it tells you how much water is remaining within the tank and needs refilling. Some air coolers come with push or sound notifications which tell about empty tanks. 

Installation and Portability:

Consider an easy installation factor as you don’t need to feel exhausted when setting up your mini air conditioner. Make sure to choose the model which is easy to move and lift. 

Noise and Performance: 

Avoid choosing the models that result in more than 56 dB, resulting in distracting effects. You should choose a portable air conditioner with maximum performance to cool the entire area.

Is It Necessary for All Types of AC to Vent?

Fixed AC units need to vent out from the window. No such thing is required for portable air conditioners. 

How Much Is the Cost of a Mini Air Conditioner?

The price of mini air conditioners varies from 200$-1000$ depending on the features, brand, and unit type.
