Description of W21

The W21 is an ice-cooling transparent travel fan that delivers an instant refreshing breeze wherever you go. A built-in cooling module pairs with turbo airflow to beat the summer heat, while the transparent PP+PC shell lets you dress it up with DIY stickers for a look that is truly yours.

Three-in-one design means you can hold it, stand it on a desk, or hang it from a bag or belt with the retractable carabiner. Weighing only 180g with a 1200/2000mAh battery, it runs 3-6 hours per charge and stays below 36dB — quiet cooling for offices, commuting and travel.
