Best Portable Air Conditioner

If you struggle with warmer temperatures, investing in an air conditioner is a good idea. If you want something that can be used to cool air around the home, a portable air conditioner is the best option. You have a range of available options when it comes to portable air conditioners. You can keep things ultra-compact with portable air coolers, or instead opt for larger units that can be wheeled between spaces thanks to built-in casters. Need more help finding the perfect air cooler for your needs? Our buying guide has all the details you need to know when selecting the best portable air conditioner.

Cooling Performance

One of the main things to remember when picking a portable air conditioner is that they are usually less powerful than models designed to remain in one place. However, you can still enjoy a considerable amount of cooling output from a portable model. Look for BTU ratings when selecting air conditioners, as this will give you a clear idea of how powerful a unit will be. The higher the BTU rating, the cooler temperatures you can expect. A higher BTU rating will also usually mean you can expect to cool a larger area.

Multiple Modes

In addition to conventional cooling modes, an air conditioner may provide you with extra functions. These include a fan mode, as well as a humidifying or dehumidifying function. If you are looking for a unit that can add moisture to the air, bear in mind that the additional water tank will make your air conditioner less portable.


Obviously, you want a portable air conditioner to be easy to move. Smaller models can be lightweight enough that they can picked up and carried with little effort. However, if you go for a larger air conditioner, this will not be feasible. Therefore, look for air conditioners that include caster wheels, as well as recessed handles so you can direct them to your desired location.

Operational Noise

Some air conditioners can be noisy appliances. If you want a unit that can be used in offices or bedrooms, go for an energy-efficient one with a low sound level. A sound level of around 55 decibels should be sufficient for most rooms, although you may want a quieter model if you want to leave it running as you sleep.

Thermostat Control

The best portable air conditioners will give you some flexibility when it comes to programming timers and other thermostat settings. If you want maximum convenience, go for a model that comes with a remote so you can make changes to your thermostat without having to use the onboard controls.
