This portable AC from Whynter comes with a powerful dual hose system, which helps cool rooms faster than other portable units. It uses outside air instead of inside air. Our testers were impressed by its versatility all year round. In dehumidifier mode, it removes up to 101 pints of moisture in a day. You can also choose the upgraded model with a heater, heating up to 77°F.

Testers appreciated the programmable timer, allowing you to set it to turn on before you get home. You can check the temperature on the digital display. Although the exhaust hose needs to go out a window, it extends up to five feet, giving you flexibility in placement. The included storage bag adds convenience for storing the unit when not in use.

BrandBLACK+DECKERProduct Dimensions16.5″D x 26″W x 11.5″HCapacity350 Square FeetCooling Power8000 BTUColorWhiteWeight‎ 45.8 PoundsNoise Level‎ 54 dB

Consider this unit for cooling your bedroom quietly through the night. It’s quieter than other portable air conditioners and weighs just 45.8 pounds, making it lighter than most. However, its quieter operation and compact size mean it has a slightly less powerful fan, resulting in slower air speeds compared to other models.

This choice is suitable for smaller spaces like offices, apartments, or small bedrooms. The filter slides out from the back for easy cleaning. Also, the remote control included allows you to adjust settings without interrupting your work or getting out of bed.

We appreciate the ability to switch between fan mode, cool mode, or dry mode. You can adjust the environment based on the weather conditions. The controls on the machine are straightforward and user-friendly.

How We Tested These Portable Air Conditioners?

In our testing process, each portable air conditioner underwent the same series of tests to evaluate both its performance and user-friendliness.

To gauge performance, we conducted a cooling test in a 200-square-foot chamber equipped with temperature sensors placed strategically around the room. 

After heating the room with a space heater, we ran each unit for two hours, recording measurements every minute. This allowed us to assess how quickly each air conditioner could cool the room and how effectively it distributed the cooled air.

In addition to performance, we assessed the usability of each unit, noting any differences in control layout and ease of setup and operation. 

Factors to Consider When Buying Portable Air Conditioners

Here are some important factors you must consider when choosing portable air conditioners:

Cooling Capacity

Portable ACs are rated based on their cooling capacity, measured either in total square footage or British Thermal Units (BTUs). 

BTUs may seem confusing, but remember, higher numbers mean more power. Typically, an 8,000 BTU unit cools up to 350 square feet. 

Make sure the AC’s power matches your room size. If your room is bigger, you need a more powerful AC.

Energy Efficiency

Pick ACs with an ENERGY STAR label. These ones save more electricity and help lower your energy bills. Also, consider smart ACs that you can control with your phone for extra convenience and savings.

Size and Position

When buying a portable air conditioner, make sure it fits near a window with enough space around it to function properly. While cooling power is crucial, avoid purchasing a unit that’s too big for your space.


While all portable air conditioners can be moved, not all are equally easy to transport. If you plan to move the unit between rooms, look for models with wheels. Also, consider the unit’s weight, especially if you’ll be carrying it up and down stairs.

Noise Level

Air conditioners can be noisy due to the motor and fan. While some may tolerate the noise for relief from the heat, others prefer quieter operation, especially when used frequently. Before choosing, check reviews for comments on noise levels.

Timer and Remote

Many portable ACs include a timer, allowing you to schedule when it turns on/off. This feature is beneficial for maintaining a comfortable temperature and saving energy costs.
