Battle the Relentless Heat with These 8 Best Portable Air Conditioners

Keep it cool. (no puns intended)

It is undeniable that the evolution of technology has dramatically transformed the world today and most importantly, refines the quality of human lives. 

If you’re still overwhelmed by the price of air conditioners they’re not the only one that can greatly relieve the unforgiving hot weather. Instead, portable air conditioners are here to offer you an incredibly convenient solution that will fit the bill.

What are the differences between portable air conditioners and air coolers?

Even though both air conditioners and air coolers combat the sweltering heat with a fresh cooling effect, they vary significantly in their operating mechanisms. 

Installed with a chemical coolant, portable air conditioners circulates warm air through the conditioning cycle and blow out cooled air while the remaining heat is vented out via exhaust hose. 

However, air coolers rely on the basic concept of evaporation. When hot, dry air is drawn into the air coolers, it passes through damp water-soaked pads where water evaporating occurs and results in a chill ambient temperature. 

(Portable) Air Conditioners vs. Air Coolers

Humidity Effect

Speaking of sweaty humid weather, the air conditioner is a greater option than the air cooler to acting as a dehumidifier. It removes heat and moisture from the air to keep the room comfortably cool whereas the air cooler usually adds humidity to the air. 


Having said that, the air cooler delivers cool, moisturised air, but it is necessary to ensure a constant flow of dry air for it to function efficiently. In other words, it works best for outdoor or in a room with door and windows opened to keep the room from clamminess and discomfort.

Meanwhile, an air conditioner needs to work in a closed space to prevent an increase in humidity level whilst holding in the cooled air. Most of them come with a venting kit which helps to drain heat and moisture from air.

Energy consumption 

Unlike an air conditioner, the air cooler utilizes water and simple motors to chill the surrounding air. Not only does it make air cooler an eco-friendly option, but it also empowers the air cooler to be 75% more energy efficient than an air conditioner. 

But then again, air coolers needs a constant air flow for it to stay efficient. Whereas, portable air conditioners introduces air movement into a space, preferably enclosed. 

So if a room is naturally hot despite the presence of a window, the air conditioner might work better in cooling it off. If you prefer natural cool air, provided that there’s good air flowing into the space, air coolers are great.

All in all, your preference for either portable air conditioners or air coolers depends on the climate at your living area, budget and versatility.
