New Waist Portable Fan Offers Over 100 Hours of Cooling for Harsh Outdoor Work Environments

Addressing Market Challenges

The rising summer temperatures in Japan, exacerbated by global warming, have led to thousands of annual emergency transports due to heatstroke among outdoor laborers, as reported by the Ministry of Health, Labour and Welfare. This has driven a significant increase in demand for heat countermeasures in primary industries and outdoor service sectors. Existing general-purpose waist fans typically feature smaller 6000mAh batteries, offering only about 30 hours of operation even on low settings, necessitating mid-day recharging for workers on full-day shifts.

Furthermore, many budget-friendly products lack dustproof and splashproof structures, leading to frequent malfunctions from mud, construction dust, or rain during delivery. Traditional models also often lack additional features such as emergency lighting or smartphone charging, limiting their utility during disasters or night work.

In collaboration with national agricultural cooperatives, construction industry associations, and major delivery companies, the development division conducted 10 months of durability tests, airflow evaluations, and continuous operation verifications under real-world conditions. This rigorous testing resulted in a waist fan that combines a compact body with extended operation capabilities, powered by an optimally placed integrated large-capacity lithium battery, thereby meeting diverse user needs.

Six Core Product Features

1. Integrated 10000mAh Battery for Up to 100 Hours of Operation

The device incorporates a PSE-certified 10000mAh integrated lithium polymer battery, with an integrated design that enhances dust and water resistance by avoiding a separate battery replacement structure. It achieves up to 100 hours of continuous operation in quiet mode (airflow level 1), approximately three times the runtime of comparable products. This eliminates the need for mid-shift charging during a full day of outdoor work. The built-in battery protection IC automatically prevents overcharging, over-discharging, overheating, and short circuits, extending battery life and overall product durability. It supports Type-C fast charging, reaching full charge in approximately 5 hours, and can operate while charging.

2. 5-Level Airflow and Independent Physical Buttons

An improved independent 3-button layout separates controls for the flashlight, airflow adjustment, and strong wind mode. A long press powers the device on/off, while single taps cycle through 5 airflow levels (gentle breeze to super strong wind). This allows for intuitive operation even when wearing thick work gloves in construction or agricultural settings. Equipped with a high-airflow brushless motor delivering a maximum wind speed of 12.0m/s, it rapidly evaporates sweat, lowering the WBGT index and reducing heatstroke risk. A front digital LCD screen displays real-time battery percentage and current airflow level, enabling users to anticipate when recharging is needed.

3. USB-A Output Mobile Battery Function

A USB-A output port on the side allows the internal high-capacity battery to power smartphones, intercoms, or small surveying equipment. This feature is useful for charging phones in the field, making emergency calls, or as a portable power source for small electronic devices during outdoor camping. The universal Type-C input port is compatible with various charging environments, including mobile batteries, AC adapters, and in-car USB terminals.

4. LED Flashlight and SOS Emergency Flashing Mode

Long-pressing the light button cycles through three modes: steady light, SOS emergency flashing, and off. This serves as a simple light for night work in fields or warehouse inspections. During power outages caused by typhoons, heavy rains, or earthquakes, the SOS flashing can emit a rescue signal, making it an ideal emergency item for disaster preparedness kits.

5. IP Dustproof, Splashproof, and Shock-Resistant Exterior

The fan’s exterior features an integrated elastic silicone buffer layer, providing dustproof, splashproof, and drop impact resistance. This significantly reduces the risk of failure in demanding environments such as agricultural muddy fields, construction site dust, or rainy outdoor deliveries. A low-noise motor ensures quiet operation, with approximately 48dB at low wind settings, allowing for use in tents during camping or during breaks in vehicles without excessive noise. Weighing approximately 375g, its lightweight design minimizes strain when worn on the waist for extended periods.

6. 4-Way Versatile Use Design and 3 Color Options

Standard accessories include a metal waist clip and an adjustable nylon neck strap, allowing for four distinct usage styles: waist-mounted for outdoor work, neck-worn for hands-free activities like walking or fishing, self-standing as a desk fan for indoor or camping use, and handheld for golf or other outdoor leisure activities. It is available in three colors: orange, military green, and dark gray, allowing users to choose according to their workwear or outdoor apparel.

Wide Range of Application Scenarios

• Industrial Sector: Heat countermeasures for long-duration outdoor work by civil engineering, construction, and painting workers, road traffic guidance staff, and indoor high-temperature work for warehouse sorting staff.

• Primary Industry Sector: Outdoor heatstroke prevention for rice paddy and field farmers, fruit growers, and fishery workers, enabling full-day operation during long hours of field work.

• Logistics and Delivery Sector: Alternative cooling for delivery drivers, moving staff, and outdoor warehouse personnel during movement and cargo handling.

• Leisure and Disaster Preparedness: For outdoor hobbies such as camping, fishing, and golf, as well as an emergency item during typhoons or earthquakes, functioning as both an emergency light and cooler in disaster preparedness kits.

Purchase Benefits and Product Warranty

All purchasers receive an adjustable neck strap, a Type-C charging cable, and a detailed Japanese instruction manual. The product has obtained PSE electrical safety certification and comes with a manufacturer’s official 1-year warranty, offering free repair or replacement services for initial defects or natural failures under normal use. As a launch commemoration, limited-time discounts are available during the first month of sale on the official Rakuten and Yahoo stores. Special business-exclusive pricing is also offered for bulk corporate and agricultural cooperative purchases.
