While you’re there, don’t forget to read our mini AC buying guide, which explains how to choose a mini air cooler that perfectly suits your needs.

Personal air cooler vs air conditioners

A personal air cooler or “mini air conditioner” is actually an evaporative air cooler, which pulls the warm air from your room and runs it through the cool water it has in its tank. That’s how it manages to decrease the overall heat in the room. Mini evaporative air coolers are a more affordable option, but aren’t optimal for humid spaces.

On the other hand, an air conditioner absorbs heat by utilizing a refrigerant fluid. It releases cold air to decrease both temperature and humidity in the room. This process requires a lot of energy and can make your electricity bill skyrocket.

Why choose a personal mini air conditioner rather than a portable AC or fixed AC unit?

Here is why a personal mini air cooler can be a great alternative to purchasing a traditional AC unit.

Personal air cooler benefits

If you still haven’t set your mind on purchasing a small portable air conditioner for personal use, here is the list of benefits that can help you make the right decision:

  • Reduce costs, but keep the area cool – why would you waste your money on cooling the entire home? Instead, a mini air conditioner allows you to focus on the area around you to reduce utility bills.
  • A portable product – whether you are heading camping, or you want to turn a unit in a mini AC for car, personal air coolers (desktop-sized ones) are ideal. You can use them on the go as long as you have a portable battery charger.
  • It doesn’t take a lot of space – these units are both compact and light. They do not take much room, and moving them is easily done in a couple of seconds.
  • Plug-and-play and user-friendly – for a window-mounted AC unit, you need to comply with all the local regulations and building rules, and you need a special installation. However, there are no restrictions for using a personal air cooler, and all you have to do is fill up the water tank (no drilling, ducts, or hoses).

Limits of personal air coolers

There is no such thing as a perfect product, and personal space coolers have some limitations, too. Here are their main disadvantages:

  • They can get noisy – it is important to note that the noise level varies from one unit to another. However, even the best portable air conditioner can be noisy, especially if you adjusted it to the highest speed.
  • Limited cooling capacity – the cooling surface varies depending on the cooler, but most of them are really just for your personal space (a radius of a few meters). You definitely can’t cool multiple rooms unless you use more than one mini cooler.
  • You need to monitor the water tank level – most tanks will keep the device running for hours. However, you should monitor the water level and refill when necessary. The good news is that some products have an indicator that will inform you when the water level is low.
  • Not adapted to humid climates – the evaporative air cooling process doesn’t work very well in humid areas. They are best for dry climates.

Personal air conditioner buying guide: how to choose the best mini AC for you?

It is not easy to find the ideal personal space cooler for your needs. That is why we prepared a buying guide that will help you make a smart decision.

Cooling area

Personal air coolers are mostly focused on cooling down space around you. However, the cooling surface may vary depending on the unit:

  • Desktop mini air coolers generally cool the air within 1 to 5 square meters (10 to 50-foot radius)
  • Larger, portable evaporative air coolers tend to have a bigger reach, cooling around 40 to 50 square meters (400 to 500-foot radius)

Manufacturers generally list the cooling capacity of their air cooler in the product description.

Operating time on one tank

The longer the cooler can last on a single tank, the less time you spend refilling it! The operating time on a single tank varies depending on the unit and the tank capacity.

It also depends on which mode you set your personal cooler on; if it’s always set on its highest (most powerful) mode, it will use up the water more quickly. In any case, the chances are that it will last at least several hours.

If this is an important feature to you, you should check the unit’s tank capacity or specified operation time. Additionally, you can take a look at how many pints or liters per hour of water the cooler utilizes.

Extra features

Apart from the main features, here are some additional factors to keep in mind when purchasing a personal air cooler:

  • Wi-Fi connectivity – it gives you a unique option to control the unit remotely. In most cases, you will do the controlling part via a mobile app.
  • LED color lighting – on some units, they only serve to indicate that the unit is running. However, some coolers also have multiple colors available (ambient color lighting), and you can use them as a lamp when it is dark.
  • Water level indicator – it will tell you how much water is left in the tank and when you need to refill it. Some coolers notify you via sound notification or a push notification on your smartphone when the tank is empty.
