Problem & Solution
Stuffy office cubicles, warm dorm rooms, and hot summer camping tents make staying focused or sleeping comfortably nearly impossible. Carrying around bulky traditional fans is impractical, while cheap disposable hand fans lack the continuous power and adjustability needed for effective cooling.

Powered directly via any standard USB port, laptop, or portable power bank, it eliminates battery anxiety while giving you full control over your personal climate with three distinct speed levels.
Thanks to its 360-degree vertical rotation, you can direct a refreshing breeze exactly where you need it most—whether you are working late at your computer desk or unwinding inside a camping tent. It transforms oppressive indoor heat into a soothing, quiet breeze at a fraction of the cost of standard fans.
