Sanwa Supply has introduced the FAN-USB2BK, a portable belt fan designed for hands-free operation. The device targets users who need cooling while keeping their hands available for other tasks. It achieves this through dual mounting options that allow it to be worn securely.
Adjustable airflow and long battery life target users needing hands-free cooling.
The fan features a semi-solid lithium-ion battery with a capacity of 3,000mAh. This battery type offers enhanced safety compared to standard liquid electrolyte cells. Users can recharge the device using a USB Type-C interface. The unit weighs approximately 157g and measures 77 by 43 by 75mm.
Wind speed is adjustable in 100 distinct steps, reaching a maximum of 5.7m/s. Battery life varies significantly based on the selected speed. The fan runs for 10 hours at 1% wind speed but only lasts 2.5 hours at maximum output. Noise levels range from 55dB at 20% wind to 71dB at full power.
The FAN-USB2BK is available in Japan for 6,160 JPY, which is about $39.32. The price includes the standard clip-on mount and a neck strap for versatile wearing styles. No other regional pricing or availability details have been provided.
Sanwa Supply has not confirmed a launch window for markets outside of Japan. The company has not disclosed long-term durability metrics for the semi-solid battery. Further details on the product's performance in high-temperature environments remain unclear.
