The Evapolar evaSmart is a compact 3-in-1 device that cools and humidifies the air using evaporative technology. It features a removable water tank, LED light, and can be controlled via a mobile app or smart home services. It is suitable for use in cars, on desks, or in tents, designed to cool your personal space rather than an entire room. Utilising evaporative technology, this personal cooler is effective in hot, dry environments and can provide a cool breeze within a 3 - 5 feet range. This device uses only 12.5W of power, offering an energy-efficient solution that can complement traditional air conditioning by reducing dryness and energy use. It performs best in environments where relative humidity does not exceed 70%. Featuring Evabreeze technology, which combines cooling and humidifying, the unit is made with durable basalt fibers, ensuring safety. Note: The color of the evaBreeze cartridge material may vary, and a small amount of basalt dust inside the device is normal. The EvaSmart air cooler is portable and quiet, powered via USB from power banks, laptops, or a car power outlet with at least 2.5A 5V. With no installation needed, it offers convenience whether you're traveling, working, studying, or relaxing at home.
