100speed handheld semiconductor cooling fan with USBC power — batteryless design, adjustable airflow, and quiet operation Key benefits Rapid, targeted cooling: Semiconductor cooling technology provides consistent, localized temperature reduction for fast relief from heat or stuffy environments. Good for continuous use without performance drop. Precise control: 100speed adjustable airflow lets you finetune cooling intensity from gentle breeze to strong airflow for different needs. Simple power options: Batteryless USBC compatibility works with a wide range of USB power sources (power banks, laptops, USB wall adapters) for flexible, reliable operation. Low noise for focused use: Designed for quiet operation so it won't disrupt work, study, or sleep. Portable and practical: Handheld form factor fits on a desk, in a bag, or in one hand for onthego cooling. What makes it stand out Semiconductor cooling core delivers a different cooling method than standard fanonly devices, producing faster localized cooling. Wide speed range (100 settings) gives more control than typical multispeed fans. USBC power eliminates the need for batteries and simplifies charging and power management. Compatibility and performance Power: USBC input; compatible with common USB power sources. Operation: Continuoususe design suitable for desk, travel, or extended sessions. Form factor: Handheld and compact for easy placement on desks, in tents, or beside a gaming setup. Practical use scenarios Home or office desk: Place beside your monitor for steady, quiet cooling during work or study sessions. Outdoor trips or camping: Run from a power bank to stay comfortable when shade and airflow are limited. Intense gaming or streaming: Maintain continuous thermal comfort during long sessions without noisy interruptions. Who it's for Students, office workers, and outdoor enthusiasts who need fast, reliable cooling. Anyone wanting adjustable, quiet, batteryless cooling powered via USBC.
