'Non-Exploding' Becomes the New Summer Standard with Launch of 5-Way Handy Fan Featuring Next-Gen Quasi-Solid-State Battery

Osaka-based YSN Co., Ltd. has announced the release of a handy fan featuring 'quasi-solid-state battery' technology, a next-generation energy storage solution, to minimize the growing risk of fires and explosions associated with portable fans.

Product Overview - Product Name: 5-Way Handy Fan with Quasi-Solid-State Battery - Model Number: B1-KS001WH - JAN Code: 4571679742967 - Launch Period: Rolling out from mid-April 2026 - Availability: At electronics retailers nationwide, including Joshin (web only), ZOA, Nojima, Bic Camera, Yamada Denki, and Yodobashi Camera.

Development Background: Rising Heat and Latent Battery Risks As Japan has experienced record heatwaves in recent years, handy fans have become essential items. However, their popularity has been accompanied by a sharp increase in incidents of rupture and fire involving lithium-ion batteries. Driven by a desire to provide customers not only with coolness but also with 'absolute peace of mind,' YSN has decided to adopt the game-changing quasi-solid-state battery.

YSN's Pursuit of Unmatched Safety The fan is equipped not only with the highly safe next-generation battery but also with an advanced proprietary IC chip that provides multiple protection functions (overcharge, over-discharge, over-voltage, over-current, short-circuit, IC overheat protection). This creates a dual safety system combining 'physical' and 'system' measures. The product is also compliant with Japan's Electrical Appliances and Materials Safety Act (PSE certification). Furthermore, it includes a malfunction prevention feature to prevent accidental activation inside a bag.

Three Key Advantages of Quasi-Solid-State Batteries 1. **Ultimate Safety**: Less flammable and less prone to explosion. Unlike conventional batteries containing flammable liquid electrolytes, this battery uses a clay-like, near-solid material. This dramatically reduces the risk of thermal runaway, fire, and explosion, even in cases of impact, pressure, or overcharging. 2. **Incredible Stamina**: Up to 16 hours of continuous operation. The 5000mAh high-capacity battery, combined with the high energy density of the quasi-solid-state technology, enables extended use. 3. **Exceptional Longevity**: Four times the charge cycles of typical batteries. With no risk of liquid leakage and a longer cycle life, this is a sustainable fan designed to perform for many seasons.

'5-Way' Versatility for Various Scenarios This product is designed to fit any lifestyle with its five modes: - **Handy Style**: For carrying on the go. - **Desktop Style**: For office or desk work. - **Neck-Hanging Style**: Frees up both hands with the included strap. - **Smartphone Stand**: Enjoy cool air while watching videos. - **Mobile Battery**: Functions as a 5000mAh external power source to charge a smartphone in emergencies.
