Background
The widespread adoption of smartphones and mobile devices has increased the importance of portable power sources for daily life. Concurrently, there is a growing demand for items used at games and outdoors to possess both aesthetic design and elements that reflect support for a team.

Product Features
Hanshin Tigers Logo Design Model
The mobile battery features designs printed with the ‘HANSHIN Tigers’ and ‘Tigers Girls’ logos. The powerful black body utilizes the iconic ‘HANSHIN Tigers’ logo, embodying the fierce spirit of the Hanshin Tigers. The elegant white body incorporates the ‘Tigers Girls’ logo, representing the Tigers cheerleading squad, resulting in a refreshing aesthetic. The high-quality print ensures vibrant colors and resistance to wear over extended use.
Enhanced Safety with Semi-Solid Lithium-Ion Battery
The adoption of a semi-solid battery provides a design that prioritizes safety compared to traditional lithium-ion batteries. Semi-solid batteries reduce the liquid content compared to conventional ternary lithium-ion batteries, preventing electrolyte leakage and successfully mitigating risks such as ignition. The battery is equipped with multiple protection functions against overcharge, over-discharge, short circuit, and temperature fluctuations. It has demonstrated its safety in nail penetration tests, where it did not ignite or emit smoke and remained functional as a mobile battery. Compared to conventional lithium-ion batteries, it offers a longer lifespan and less degradation, ensuring stable performance and safer use over time.
Wireless Charging Support
The product supports wireless charging, allowing smartphones to be charged by simply placing them on the device. It supports up to 15W output, enhancing convenience for daily use. Furthermore, wired output supports rapid charging up to 20W, and simultaneous use with wireless charging is also possible.
Compact and Portable Design
Weighing approximately 132g and featuring a compact size, the mobile battery is easy to carry, making it ideal for game days and outings.
