China’s GB 47372-2026: New CCC Power Bank Requirements

The New CCC Power Bank Standar

CNCA released Announcement No. 7 of 2026 on May 31, 2026. Through this announcement, the newly finalized national standard GB 47372-2026, “Safety Specification for Power Banks,” became part of the compulsory certification framework covering power banks and their batteries. The standard becomes effective on 1 April 2027, replacing the trial arrangement that certification bodies had followed since power banks and lithium batteries were first brought fully under CCC rules in August 2025.

This is not a single-document update. A companion set of implementation rules accompanies the new standard, and the two together determine how power banks, battery cells, and battery packs will be tested, categorized, and monitored going forward.

Scope: Which Products Fall Under the New CCC Power Bank Standard

The updated framework sorts affected products into three groups, each tied to its own combination of standards:

• Finished power banks and portable outdoor energy storage units — tested against a bundle of three standards together: GB 4943.1, GB 31241, and GB 47372.
• Batteries built for phones and other everyday digital devices (excluding e-cigarette batteries) — remain under GB 31241 only, unaffected by the new addition.
• Cells and packs built specifically to pair with power banks or outdoor storage units — sit in a middle category, tested under both GB 31241 and GB 47372.

The practical effect of this split is that finished power banks and their purpose-built batteries carry the full burden of the new standard, while batteries intended for general consumer electronics follow a separate and considerably lighter path, covered further below.

The Highlight of GB 47372-2026

Rather than adding routine performance checks, GB 47372-2026 targets how products behave under stress. Testing now looks closely at thermal stability when a battery is pushed toward failure and at how protective circuitry responds during abnormal charging or discharging events. These requirements sit on top of the electrical safety and EMC testing that products already undergo under standards like GB 4943.1, rather than replacing them.

Because of this added layer, applicants filing after the effective date should expect certification bodies to request more granular documentation than before, particularly around cell sourcing and battery management system design, since these design choices directly influence how a product performs under the new abuse-testing criteria.

Revised Implementation Rules for CCC Power Bank Certification

The implementation rules paired with GB 47372-2026 carry the designation CNCA-C09-02:2026, superseding the trial version, CNCA-C09-02:2025, that had governed certification since mid-2025. Between the announcement’s release and 31 March 2027, applicants filing new CCC submissions are given a choice: they may proceed under either the outgoing 2025 rules or the incoming 2026 rules, whichever better fits their current testing timeline.

That flexibility ends once the window closes. Every new CCC application filed from 1 April 2027 forward must be processed exclusively under CNCA-C09-02:2026, together with the full standard set it references, with no option to fall back on the earlier rules.

Certificate Conversion Deadline and Exceptions

Companies already holding CCC certificates for complete power banks and their dedicated batteries face a firm cutoff. Before 31 March 2027, they must finish any supplementary testing the new standard requires, pass an on-site factory audit, and migrate each certificate to the new rules. Certificates left unconverted past that point are revoked automatically, with no grace period described in the announcement.

Manufacturers of batteries for general digital devices are treated differently. Rather than a fixed migration deadline, their certificates carry forward under a natural transition approach, meaning compliance with the new rules only becomes necessary when a certificate comes up for renewal or when the underlying product design changes. This gives that segment of the market considerably more breathing room than power bank and matched-battery certificate holders.

Key Takeaways

• Manufacturers of finished power banks and their dedicated matched batteries face a hard deadline: certificates not migrated by 31 March 2027 lapse automatically, so factory audits and supplementary testing should be scheduled well in advance rather than close to the cutoff.
• The overlapping standard set (GB 4943.1, GB 31241, GB 47372) means certification planning should account for all three simultaneously rather than treating GB 47372-2026 as a standalone addition to existing testing.
