This 3-in-1 portable air cooler fan is a multi-functional personal cooling device designed to serve as an evaporative air cooler, a mist humidifier, and a traditional desktop fan. It utilizes a 500ml to 600ml top-fill water tank to facilitate an evaporative cooling process, where water is atomized into a fine mist and blown forward by high-efficiency 3D spiral-cut blades. This system can effectively lower the surrounding temperature by several degrees while simultaneously adding moisture to the air, making it particularly useful in dry or arid environments where standard fans may only circulate hot air.

The unit is engineered for personal space cooling—typically effective within a 3 to 4-foot range—and is powered via a universal USB connection, allowing it to be used with laptops, power banks, or car chargers for maximum portability. Users can customize their experience through three adjustable wind speeds and multiple spray modes, with some models offering a programmable timer (1, 2, or 3 hours) for automatic shut-off. For enhanced nighttime utility, it includes an integrated 7-color LED mood light that can cycle through colors or remain fixed on a single hue, doubling as a soft nightlight. Its compact, lightweight design often includes a leather or plastic carrying handle, making it a versatile companion for office desks, bedside tables, or even outdoor activities like camping.
