Peiyuu’s neck fan solves a simple problem: how to get hands-free cooling without the bulk. The 4000mAh battery is the key. It’s large enough to power the fan for hours, yet the whole unit remains light and wearable. The foldable design means it transitions from a neck fan to a stable desk fan in seconds.

An LCD display shows your exact speed setting and remaining battery percentage. That’s a practical touch you don’t get on most personal fans. The six speed settings offer real range, from a gentle breeze to a legitimately strong airflow. On its highest setting, the brushless motor is still quiet. It won’t disrupt a phone call or focus.

The lanyard is comfortable for short periods, though you’ll feel its weight after a full day. It’s best for active use like walks, chores, or desk work, not for sleeping. As a compact, versatile air mover, it delivers focused cooling exactly where you need it.
