What is Polar Chill Portable AC? The Polar Chill Portable AC falls into the category of mini air coolers. Like almost all of these products, this air conditioner is small and handy and can be transported to a new location with just one movement. The manufacturer offers this product as a 3-in-1 solution. In addition to cooling the immediate ambient air, the filters it contains are designed to filter dust from the air and improve the humidity of the room. After the air is sucked in, a fan ensures that the cooled air is released back into the room air. You can choose between three different settings and can thus react to the respective temperature in the room. The manufacturer offers the Polar Chill Portable AC with a battery.
