China has released the mandatory national standard GB 47372-2026, introducing enhanced safety and technical requirements for mobile power supplies (power banks). The regulation includes new protections against extreme conditions such as overcharging, high temperatures, and mechanical stress, as well as lithium precipitation detection after battery aging to reduce internal short-circuit risks.

The standard also introduces a needle puncture test, real-time monitoring of battery parameters, and mandatory abnormal event recording functions. Additionally, it requires unique product identification codes to improve traceability and consumer access to product information.

A 12-month transition period is provided for CCC certification, after which compliance becomes mandatory. The regulation strengthens manufacturing controls and is expected to improve product safety, market regulation, and consumer protection.

This represents a high-impact regulatory development, as it introduces a mandatory national standard with significant new technical, safety, and traceability requirements for power banks, directly affecting product design, manufacturing, certification, and market access in China.

The impact is high because compliance will be legally required for market entry, requiring manufacturers to implement new testing methods, monitoring systems, and production controls, with direct implications for costs, supply chains, and certification processes.

Key reasons for high impact:

• Mandatory national standard (GB 47372-2026)
• New safety tests (needle puncture, lithium precipitation detection)
• Real-time battery monitoring and data storage requirements
• Unique product identification and traceability obligations
• Stricter manufacturing and raw material controls
• Mandatory compliance after transition period (April 2027)

Who?

• Power bank manufacturers
• Battery producers and suppliers
• Electronics brands and OEMs
• Testing laboratories and certification bodies (CCC)
• Importers and distributors in China

Conclusion

This regulation significantly raises the safety and compliance bar for power banks in China, with mandatory requirements that will reshape product design, certification, and manufacturing practices. Its broad scope and binding nature make it a high-impact development for the battery and consumer electronics industry.
