On April 3, 2026, the mandatory national standard GB 47372–2026, "Technical Specification for the Safety of Mobile Power Banks," was officially released and will come into effect on April 1, 2027. This standard applies to mobile power banks-commonly referred to as "power banks" or "outdoor power supplies" (including portable mobile power banks and portable energy storage devices)-and introduces several key safety requirements building upon existing general mandatory national standards.
- Enhancing battery intrinsic safety: The introduction of a needle penetration test clearly improves the safety protection capabilities of power banks under harsh conditions such as high temperatures, overcharging, and compression.
- Reduction of long-term usage risks: Incorporate lithium leaching detection after cyclic aging, specify the recommended safe service life, and remind consumers to replace products with reduced safety performance promptly.
- Implement unique coding management: Each product must have a unique code, allowing consumers to access core information such as battery brand, thereby enhancing product traceability.
- Strengthen production process control: Establish clear regulatory requirements for the raw materials and manufacturing processes of portable power banks to enhance safety standards at the source.
- A 12-month transition period is established: During this period, enterprises may choose to implement either the new standard or the original standard; after the transition period ends, they must produce and sell products in compliance with the new national standard.
Furthermore, in accordance with civil aviation regulations, starting June 28,2025, passengers are prohibited from carrying power banks without the CCC certification mark, with an unclear CCC mark, or belonging to recalled models or batches on domestic flights. After the implementation of the new national standard, power banks that have already obtained CCC certification may still be carried on board provided they comply with current civil aviation regulations. It should be noted that power banks subjected to impacts, severe compression, or overcharging still pose usage risks; passengers are advised to avoid carrying such products on flights.
