Ultra-Slim 26 mm Wearable Design

The KC-F66 measures only 26 mm in thickness, allowing it to sit closer to the waist than conventional bulky wearable fans. Its compact structure supports hands-free cooling without requiring users to hold a separate device.

The upward airflow can help circulate air beneath clothing, making the fan suitable for commuting, outdoor work, gardening, warehouses and summer activities.

Air Speed up to 13 m/s

A high-speed airflow system delivers wind speeds of up to 13 m/s for focused personal cooling. The strong airflow makes the KC-F66 suitable for warm outdoor and working environments where conventional low-power wearable fans may provide limited relief.

Actual performance may vary depending on the selected setting, battery condition, ambient temperature and operating environment.

Five Adjustable Speed Levels

The KC-F66 provides five selectable airflow levels. Level 1 offers gentler airflow and longer operating time, while Level 5 delivers maximum cooling performance.

Estimated runtime ranges from up to seven hours at Level 1 to approximately two hours at Level 5, allowing users to balance airflow strength and battery life.

4000mAh Rechargeable Battery

The built-in 4000mAh battery supports extended cordless operation:

Level 1: up to 7 hours
Level 2: approximately 4.5 hours
Level 3: approximately 3.2 hours
Level 4: approximately 2.5 hours
Level 5: approximately 2 hours

Actual runtime may vary according to battery condition, ambient temperature and operating environment.

USB-C Charging with Protected Operation

The KC-F66 supports USB-C charging with a rated input of 5V⎓2A. A full charge takes approximately four hours when connected to a compatible power source.

All five airflow levels are available during cordless operation. For battery protection, up to three speed levels are available while the fan is charging.
