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.
