Powerful, safe, portable cooling in a compact design — delivers adjustable airflow, advanced cooling, and quiet operation for travel, work, and everyday use. Key benefits Strong, controllable airflow: 7 m/s airflow driven by a 3phase brushless motor at 13,500 RPM. Choose from 1–100 speed levels for precise cooling where you need it. Rapid cooling technology: Builtin double ice cooling system with a superconducting ice porcelain refrigeration device and ice porcelain refrigeration sheet creates noticeably cooler air at the outlet. Batterypowered portability: Integrated 5200 mAh battery with USBC charging lets you use the fan offgrid and recharge easily from common power banks or chargers. Safe bladeless design: No exposed blades reduces risk around children and teens while still delivering effective airflow. Quiet operation for focus and rest: ANC (Active Noise Cancellation) silencer technology minimizes operating noise, suitable for offices, libraries, and bedrooms. Realtime information: definition smart digital display shows speed settings and remaining battery power so you can plan charge times and adjust performance quickly. Ultralight and travelready: Weighs just 258 g — slips into a bag, backpack, or pocket for onthego cooling. Practical features and performance Speed control: 1–100 adjustable levels for finetuned comfort from gentle breeze to strong airflow. Motor and airflow: 3phase brushless electric motor, 13,500 RPM, producing up to 7 m/s airflow for fast cooling effect. Cooling module: Double ice cooling technology with ice porcelain refrigeration sheet delivers a perceptible, immediate coolair output. Power and charging: 5200 mAh internal battery; USBC charging port for wide compatibility with modern chargers and power banks. Safety and build: Bladeless construction reduces injury risk around children and teens; lightweight construction (258 g) for easy carry. Noise control: ANC noisecanceling silencer reduces operating sound for quiet environments. Display: definition digital screen for speed and realtime battery monitoring. Use scenarios Commuting and travel: Slip the fan into your bag and use it on buses, trains, or at airports for instant cooling without cords. Office, study, or library: Lownoise ANC operation and adjustable speeds let you stay cool while maintaining a quiet workspace; digital display shows battery so you know when to recharge. Outdoor activities and family outings: Portable 5200 mAh battery and bladeless safety make it suitable for beach trips, hikes, stroller use, or picnics while keeping nearby children safe.
