Through its role in drafting the new Chinese technical specification for power bank safety, UGREEN helps advance safety across the industry.

UGREEN, a leading global consumer technology company, has announced its participation in the formulation of China’s new GB 47372-2026 standard, which defines technical specifications for power bank safety. This underscores the brand's long-term commitment to product safety, regulatory alignment, and industry standardization.

Contributing Industry Expertise to the New Safety Standard

UGREEN’s participation in the standard-setting process reflects its position as a leading Chinese consumer technology brand, backed by globally competitive technical expertise. With a strong focus on reliability, quality control, and user-centric design, the company was able to contribute practical industry experience and insights into product safety, helping shape the standard from an early stage.

The GB 47372-2026 standard introduces a more comprehensive safety framework for power banks, strengthening requirements across battery cell safety, structural design, thermal management, electrical protection, and full lifecycle traceability. It also introduces more rigorous testing under extreme conditions and reinforces control over key components, with the aim of improving overall product reliability and safety in real-world scenarios.

UGREEN has built a structured five-part safety system across its operations:

• Traceability system: A Manufacturing Execution System (MES) enables end-to-end digital tracking, including parameter monitor, process validation, and yield management.
  
• Automated manufacturing: Key processes, including cell matching, welding, dispensing, and testing, are fully automated to ensure consistency and minimize human error.
  
• Unique serial identification: Each product carries a traceable code that identifies its production date, manufacturing facility, and battery cell information.
  
• Battery cell testing: Stringent tests, including nail penetration, lithium plating, and compression, are conducted in line with GB 47372-2026 requirements.
  
• Monitoring and alert system: A real-time monitoring system continuously tracks battery cell performance, logs anomalies, and supports full lifecycle traceability and post-event analysis.

Partnering with ATL to Advance Battery Cell Safety

To further strengthen its upstream supply chain, UGREEN has established a strategic partnership with ATL (Amperex Technology Limited), a leading global lithium-ion battery manufacturer. The collaboration ensures the adoption of high-quality, safety-compliant battery cells aligned with the new standard. By integrating ATL’s advanced cell technology with UGREEN’s system-level engineering capabilities, both parties aim to enhance consistency, reliability, and safety across portable power products.

As a contributor to the standard, UGREEN will continue to uphold safety standards that exceed GB 47372-2026, accelerate the development and delivery of compliant power products, and further strengthen its position as a trusted brand and pioneer in charging safety. UGREEN also remains committed to delivering a higher-quality overall product experience.
