Air Cooler: This cooling fan features a 1200 mAh battery that allows for 1 to 2 hours of continuous operation on a full charge. This portable air conditioner holds up to 600 ml of water and humidifies for 4 to 10 hours. The transparent water tank indicates the water level. Thanks to the built-in 1200 mAh battery and USB charging function, you can use this device wirelessly anywhere. The perfect choice for camping! Three Spray Modes: This mini air conditioner uses state-of-the-art ultrasonic spray technology to atomize water into ultrafine particles, creating cool, moist air. Choose from three spray modes and three wind speeds to suit your needs and preferences. Three atomization and humidification vents produce an ultrafine mist that quickly lowers the indoor temperature and provides cool air. Portable Air Conditioner: This water-cooled mini fan can be manually adjusted up and down by 60° to direct the cool air where you want it. Made of durable ABS, it's lightweight and easy to use. The carrying handle makes it easy to transport. (Note: This portable air conditioner is not suitable for cooling entire rooms.) Quiet Comfort: The built-in night light offers seven color options and a color gradient function for a romantic atmosphere. The ultra-quiet operation at 35 dB won't disturb your rest. On hot summer days, you can even add ice cubes to the water tank for even cooler air. Pressing the turbo button instantly activates the maximum wind speed (3 m/s) and the water jet intensity – ideal for hot weather.
