Addressing Summer Heat Challenges
Traditional portable fans often present challenges such as being heavy, bulky in bags, and difficult to carry for extended periods. In response, LAMA Store developed a new portable fan with a focus on “lightness for daily carrying” and “design suitable for women.” This resulted in an ultra-lightweight design of only 153g, combined with versatile 4-way functionality including waist, neck, handheld, and desktop use.
Product Features
Ultra-Lightweight Design for Easy Portability
Weighing approximately 153g, the device is designed for easy portability. It can be carried in a bag without adding significant burden, making it suitable for daily commutes, school, and travel.

4-Way Functionality for Various Scenes
The fan supports 4-way use: waist, neck, handheld, and desktop. This versatility allows for hands-free operation during commutes or shopping, and use as a desktop fan at home or in the office, adapting to various situations.

Internal Airflow for Heat and Humidity Reduction
When worn on the waist, the fan directs air inside clothing, efficiently circulating hot air around the back and waist. This feature helps reduce discomfort from sweat and stuffiness, contributing to more comfortable summer outings.

Large Capacity 5000mAh Battery for Long-Term Use
Equipped with a 5000mAh large-capacity battery, the fan provides reliable use for extended periods, suitable for travel, leisure activities, or sports spectating. It supports USB Type-C charging, allowing it to be used with common smartphone chargers.

5-Stage Air Volume Adjustment for Comfortable Airflow
The fan features a 5-stage air volume adjustment function, allowing users to select the appropriate airflow for various environments. This enables gentle airflow during commutes or in the office, and powerful airflow outdoors in intense heat.
