Portable rechargeable neck fan — quiet, efficient cooling when you need it Key benefits Long, reliable runtime: Builtin battery delivers up to 24 hours of operation on low speed, so the fan runs through long days without frequent recharges. USBC rechargeable design makes it easy to power up from modern chargers or power banks. Focused cooling performance: An advanced 8core turbine system creates laserfocused cold airflow that lowers skinsurface temperature by up to 20°F for immediate, targeted relief from heat. Whisperquiet operation: Aviationgrade noise reduction keeps sound at or below 25 dB. You get strong airflow without distracting noise — suitable for offices, libraries, or sleeping environments. Energyefficient and portable: 9W power efficiency balances strong cooling with lower energy use, supporting longer run times and convenient mobile use. What it does and why it matters Delivers targeted, wearable cooling: The neckstyle, portable fan directs a steady stream of air to the face and neck where cooling is most effective, helping reduce perceived heat quickly and comfortably. Rechargeable and compatible: USBC charging offers wide compatibility with current chargers and power banks so you can recharge at home, in the office, or on the go. Quiet, effective airflow: Designed to maintain powerful cooling while staying at sublibrary noise levels (≤25 dB), so it won't interrupt work, calls, or sleep. Performance highlights Battery runtime: Up to 24 hours at low speed Power use: 9W efficiency Cooling system: 8core turbine for concentrated airflow Noise level: Aviationgrade reduction ≤25 dB Form factor: Portable, neckstyle wearable fan, rechargeable via USBC Practical use scenarios Commuting and travel: Use it on public transit, in rideshares, or at the airport to stay comfortable during warm waits and transfers without needing a wall outlet. Office and study: Keeps you cool at your desk while operating quietly enough for meetings, studying, or remote work. Outdoor activities and events: Wear it during walks, outdoor festivals, or sporting events to get instant relief from heat without bulky equipment. What to expect Instant targeted cooling with reduced skin temperature (up to 20°F) using a compact, rechargeable design. Convenient USBC charging for broad compatibility with modern chargers and portable power sources. Low operational noise that preserves concentration and rest while delivering effective airflow.
