Buffalo Introduces Semi-Solid Mobile Battery: Enhanced Safety and Portability

Buffalo Inc. is set to release its new “Semi-Solid Mobile Battery (BMPBSA10000 series)” in early September 2026. This innovative product, available in Metallic Black and Silky White with a 10,000mAh capacity and 30W maximum output, will be sold at electronics retailers nationwide. The battery utilizes a semi-solid electrolyte, a departure from traditional liquid electrolytes, to offer enhanced stability and structurally suppress the risk of ignition, ensuring a safer charging experience for users, including families and children.

Addressing Safety Concerns in Mobile Battery Use

Mobile batteries have become an essential part of daily life, yet many users harbor concerns about safety risks such as ignition. According to a survey conducted by Buffalo, 52% of respondents own a mobile battery, 89% have heard of fire or explosion incidents involving batteries, and 80% expressed anxiety about mobile battery safety. To alleviate these concerns, Buffalo has adopted semi-solid electrolyte technology, which is designed to suppress fire risk during daily use and incorporates a “fail-safe” design to minimize damage in the event of an anomaly.

Stable Semi-Solid Electrolyte for Reduced Risk

The semi-solid mobile battery employs a gel-like semi-solid electrolyte, which offers superior stability compared to conventional liquid electrolytes. This design significantly reduces the structural risk of ignition and smoke emission.

Rigorous Safety Verification Through Physical and Chemical Tests

Buffalo has conducted extensive physical and chemical tests to confirm the safety of the semi-solid mobile battery. Physical tests, such as nail penetration (with a 3mm diameter nail) and crush tests (approximately 13kN), were performed to verify the safety structure under severe conditions. These tests demonstrated the stability of the semi-solid battery compared to conventional liquid electrolyte products. Users are advised not to intentionally apply heat or impact to the product.

Beyond visible risks, Buffalo also focused on unseen dangers. Collaborating with specialized domestic institutions, the company physically disassembled battery cells and recreated chemical reaction environments to collect and meticulously measure any generated gases using dedicated analytical equipment. This ensured that no harmful gases affecting humans or pets are detected in the event of product damage. Disassembly or modification of the product is strictly prohibited.

Slim, Lightweight Design with Integrated Cable for Portability

Despite its 10,000mAh capacity and various functions, the battery features a slim design with a thickness of 15.2mm and a weight of approximately 210g. This lightweight and portable design makes it convenient for daily commutes or travel.

The battery also includes an integrated, high-durability strap-type Type-C cable, approximately 23cm long, made of nylon fabric to resist breakage. Its slim connector allows use even with thick smartphone cases, ensuring reliable power supply without the worry of forgetting a cable. The high-quality cable supports up to 30W (USB PD), maximizing the battery’s inherent charging speed.

Fast Charging and Convenient Features

The semi-solid mobile battery supports 30W high-speed charging via USB Power Delivery 3.0, allowing for quick recovery from unexpected battery drain on the go. For example, an iPhone 17 can be charged to approximately 50% in 24 minutes. Actual charging times and cycles may vary depending on environmental conditions and device status.

With a 10,000mAh capacity, the battery can reliably charge modern smartphones and tablets. It can charge an iPhone 17 approximately 1.7 times, an 11-inch iPad Pro (M5) approximately 0.8 times, and a Google Pixel 10 approximately 1.2 times (estimates).

The battery also supports simultaneous charging of two devices via its integrated cable and Type-C port. A pass-through charging function prioritizes smartphone charging and then automatically recharges the mobile battery once the smartphone is full. A digital meter displays the remaining charge in 1% increments.

Buffalo’s Commitment to Safety

In addition to the semi-solid battery technology, the product incorporates multiple protection circuits, including overvoltage protection, overcurrent cutoff, temperature detection, and short-circuit prevention, to prevent anomalies and troubles. It is compliant with PSE (Electrical Appliances and Materials Safety Act) and UN38.3 (UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria).
