Introducing a New Mobile Battery with Semi-Solid State Technology
As the number of digital devices, such as smartphones, wireless earphones, tablets, and laptops, carried daily continues to grow, mobile batteries are increasingly required to offer more than just capacity. Users now demand faster charging, enhanced portability, and improved usability.
To meet these evolving needs, this product incorporates a “semi-solid state battery” which features a reduced liquid electrolyte content. The design also targets approximately 2,000 charge/discharge cycles, emphasizing long-term usability for a device that is used repeatedly every day.
This may vary depending on usage environment and charge/discharge conditions.
Six Key Features of This Product
1. Adopts a Semi-Solid State Battery
This product utilizes a semi-solid state battery with approximately 5% liquid electrolyte content. This advanced battery technology aims to deliver the performance required for future mobile batteries.
2. 10,000mAh Capacity at Approximately 190g
For an item carried daily, weight is as crucial as capacity. This mobile battery offers a 10,000mAh capacity with a body weight of approximately 190g, making it convenient for commuting, school, travel, and business trips where compact luggage is desired.

4. Equipped with 3 Ports: USB Type-C x2 + USB Type-A x1
The battery features two USB Type-C ports and one USB Type-A port, accommodating both new USB Type-C compatible devices and existing USB Type-A cables. This design is convenient for users who carry multiple devices such as smartphones and wireless earphones.

To minimize instances of forgetting to charge a mobile battery, a digital display shows the remaining battery level numerically. This makes it easier to decide when to charge before heading out.
