New 4-Way Waist Fan Released to Address Heatstroke Prevention Needs

LAMA Store, operated by L&L LivelyLife Inc., has launched a new “4-Way Waist Fan” designed to meet the growing demand for heatstroke countermeasures. This fan offers up to 45 hours of continuous operation and is equipped with a 10000mAh large-capacity battery, providing comprehensive support for summer heat in various scenarios, including outdoor work, commuting, outdoor activities, and sports spectating.

In recent years, Japan has experienced an increasing number of extremely hot days. The Japan Meteorological Agency predicts that the summer of 2026 will see temperatures above average nationwide. As awareness of heatstroke prevention rises, personal cooling devices such as waist fans, which directly deliver airflow inside clothing, are gaining significant attention.

This newly released “4-Way Waist Fan” integrates a high-capacity 10000mAh battery and a powerful motor, achieving both strong airflow and extended operational time. It is suitable for a wide range of situations, including outdoor and on-site work, outdoor activities, sports events, festivals, and daily commutes.

5 Features Responding to Market Needs

1. 10000mAh Large-Capacity Battery for Up to 45 Hours of Continuous Use

Equipped with a 10000mAh battery, this fan is designed for prolonged outdoor use. It can operate continuously for up to approximately 45 hours, ensuring reliable cooling even in environments with limited charging access, such as construction sites or outdoor adventures.

2. “Body Cooling Structure” for Direct Airflow Inside Clothing

When worn on the waist, the fan directly circulates air inside clothing, effectively reducing sweat and stuffiness. This design cools the core body, a region often difficult to reach with traditional handheld fans, thereby lowering the perceived temperature.

3. Multi-Use Design: One Device, Four Functions

This product offers versatile 4-way functionality:

Waist fan
Neck fan
Handheld fan
Desktop fan

Users can flexibly switch between modes depending on the situation, whether commuting, working on-site, or using it indoors.

4. Powerful Airflow × Lightweight and Compact Design

The fan delivers stable, strong airflow through a high-output motor while maintaining a lightweight design. This ensures minimal burden during prolonged wear, making it practical for use as a work device.

5. Addresses Heatstroke Prevention Needs in an Era of Persistent Heatwaves

Due to recent climate change, the risk of heatstroke during summer is increasing annually. This product was developed as a new heat countermeasure item, shifting from “enduring the heat” to “actively preventing it.”

Usage Scenarios

Outdoor work sites such as construction, logistics, and manufacturing
Heat countermeasures during commutes to work or school
