As the air passes through, evaporation lowers the air temperature and adds a fine mist, delivering cooler, slightly humidified airflow directly toward you. It works best in warm (above 25°C) and low-humidity environments.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What USB power source do I need for all 3 fan speeds?\u003c\/h4\u003e\n\u003cp\u003eA: Speeds 1 and 2 work with standard USB ports (0.5A–1A). To activate Speed 3 (maximum airflow), you need a power source capable of at least 1.5A — a 2A USB wall adapter or a USB 3.0 computer port is recommended.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I use ice water in the tank for extra cooling?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! Filling the 380ml tank with cold or ice water is a great way to boost the cooling effect, especially when ambient temperatures or humidity levels are high. Just be sure to keep the unit upright at all times.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this fan suitable for cooling an entire room?\u003c\/h4\u003e\n\u003cp\u003eA: This portable cooling fan is designed for personal use, providing targeted cool airflow within approximately 40 cm. It is ideal for one person at a desk or bedside and is not intended to replace room air conditioning.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I clean and maintain the fan?\u003c\/h4\u003e\n\u003cp\u003eA: Drain the water tank completely before cleaning. Wipe the exterior with a damp cloth. Periodically rinse the water tank to prevent mineral buildup, especially if you use tap water regularly.
