About this item 【Efficient Cooling】The 4-in-1 Portable Air Conditioner system combines two atomizing humidification nozzles and a booster motor with a fan speed of up to 3500 rpm. The atomizing humidification nozzle diffuses ultra-fine water mist, quickly lowering the indoor temperature and providing fresh air. You can also add cold water or ice cubes for better cooling. 【2 Sprays & 3 Fan Speeds】This Portable Air Cooler has 2 spray modes (weak spray/strong mist) and 3 fan speeds (low/medium/high). The wind direction is adjustable at 90° (left/right) and 60° (up/down). You can choose the fan direction and mode according to your needs to direct the cold air to the desired location. 【900ml Large Capacity Water Tank】This portable air conditioner is equipped with a 900ml sealed water tank, which can work continuously for 5-8 hours after filling. When the water level is low, it will automatically switch to natural ventilation mode to avoid headaches and colds caused by continuous cold wind.
