Large-capacity heat sink: A built-in 3000 cubic millimeter heat sink can reduce temperatures as low as 15°C (60°F). Simply place it near your neck for rapid cooling—ideal for construction sites, warehouse work, or after exercise. Please note: Cooling consumes more power; turn off cooling when not in use. Powerful airflow with 100 speed settings: Thanks to a 10,000 rpm motor (up to 5 m/s) and a wraparound airflow design, this neck fan offers 100% improved cooling efficiency. 100 speed settings are available, from a gentle breeze to a powerful airflow to meet your rapid cooling needs. 6000 mAh battery and LED display: The built-in 6000 mAh battery provides 2 to 12 hours of runtime (fan mode only) or 1.5 to 3 hours (including cooling). Charging via USB-C takes 4 hours; you can also use a power bank, laptop, or AC adapter for charging while using (pass-through charging). The LED screen clearly displays the current fan speed and battery level. Comfortable and quiet operation: Operating at only 35 decibels, it's ideal for use in offices or libraries. Weighing only 400 grams (0.9 pounds), it's lightweight and portable, preventing neck fatigue. The bladeless design with a fine mesh cover effectively prevents hair tangling. Safe for children, the elderly, and those with long hair. A thoughtful summer gift: This stylish and modern fan, with its hands-free neckband design, is an ideal gift for friends and family, keeping them cool and comfortable all summer long.
