Multifunctional: This portable air conditioner combines cooling, humidification, and natural wind functions. Its built-in high-volume turbine fan and evaporative cooling pad transform dry, hot air into cool air. Wide-Angle Airflow: Our air cooler uses a three-sided thickened evaporative cooling pad to achieve a 120° wide-angle airflow. Combined with a dust filter, it provides clean, cool air. 40-Liter Large-Capacity Water Tank: This evaporative portable air cooler comes with a large 100-liter water tank, providing continuous cooling for extended periods without frequent refills. Rapid Ice Crystal Freezing: Our air cooler features an open water tank design, allowing direct placement of ice crystal containers. Combined with the turbine fan, it achieves rapid cooling in just one second. Safety Design: A protective mesh at the air outlet prevents anyone from touching the motor and fan blades under any circumstances, providing maximum safety for children and pets.
