Key Features

3-in-1 Portable Air Cooler, Fan & Humidifier

This compact desktop air cooler works as a personal fan, evaporative cooler, and mist humidifier. Add water or ice water to create a cooler airflow while also helping to reduce dryness in the air.

Dual Mist Nozzles for Better Cooling

The front dual nozzles release fine water mist together with the fan airflow, helping create a refreshing cooling effect. For stronger cooling, add cold water or ice water into the tank.

Two-Speed Adjustable Wind

Choose between soft wind and strong wind depending on your cooling needs. The two-speed control makes it suitable for sleeping, working, reading, or relaxing.

500ml Large Water Tank

The built-in 500ml water tank reduces the need for frequent refills. The large top opening makes it easy to add water or ice water directly.

USB Rechargeable with 1800mAh Battery

Equipped with a built-in 1800mAh lithium battery, this mini air cooler can be used without being constantly connected to a power outlet. It supports USB charging and can be powered by a USB adapter, laptop, power bank, or car USB port.

15° Manual Air Outlet Adjustment

The front air outlet grid can be manually adjusted up and down by about 15°, allowing you to direct the airflow to a more comfortable angle and avoid direct blowing discomfort.

Use clean water only. Do not add essential oils, perfume, corrosive liquids, or chemical additives into the tank. Empty and dry the tank when not in use for a long time. Keep the unit upright during operation to avoid water leakage.
