A battery-powered air conditioner is a pretty handy little unit that allows you to cool down yourself when the heat is on. These mini ACs are extremely useful because you can conveniently place them on your desk when feeling hot. 

They are portable, so you can carry them wherever you want. You can take them to your office, and use them in your home. They are great for traveling as well.

Your trusty little cooling partner will keep everything comfortable for you. And what is even better is these units are rechargeable. They run on batteries so that you won’t need any electricity around you either. So, no plugs and wires to deal with.

What to Look for When Buying A Battery-Powered Air Conditioner


These units need to be compact. There is no point in going for a battery-powered AC if it’s not mobile. So, easy carrying is going to be the number one priority here. 


A battery powered air conditioner with a humidifier comes with a tank. Being too focused on compactness may compromise the tank capacity and hence its operation time. A battery-powered AC with a larger tank will keep working for a longer period depending on the fan speed.

Charging options

There are different charging options available. Some can be charged via a USB while others can be charged, more conventionally, with an electricity outlet. 

A USB charging option will be handy because you can use your laptop to charge your AC relatively easily. But if you have close access to an outlet, you can go for that option as well. 


The airflow needs to be enough to cool you down. If it doesn’t come with enough airflow, then your purchase is going to be meaningless. So, look for the CFM of the unit that you are considering.

Noise level

Noise levels are equally important. If a unit makes too much noise, it will create a headache because it is placed next to you. So, you need to have a look at the decibels as well. The best ones will be under 50 dB.

Additional features

Some small units also come with different modes. You will find that some of these battery-powered air conditioners come with inbuilt humidifiers as well. Some of them also come with night lights as well. 

Is a battery-powered air conditioner worth it? 

Yes, these small battery-operated units work pretty well, and they can easily handle an area of up to 100 square feet. Some of them can take an even bigger area, but they won’t be suitable for personal use. 

Do I need to drain these battery-operated air conditioners? 

If you are using a battery-powered AC that comes with a humidifier, you will have to drain it. Otherwise, most units are evaporating the tank on their own pretty well, and you won’t have to drain them. It would be better for you to consult the owner’s manual for your unit.
