Guangdong Energy Storage Testing Technology Co., Ltd. | June 23, 2026
On March 31, 2026, China published its first mandatory national standard specifically for power bank products – GB 47372—2026 "Safety Technical Specification for Power Banks" – which will be fully enforced from April 1, 2027. On May 31, 2026, the Certification and Accreditation Administration of China (CNCA) issued Announcement No. 7 of 2026, officially incorporating GB 47372—2026 into the CCC (China Compulsory Certification) certification scheme for power banks, alongside the new implementation rules (CNCA-C09-02:2026).
This marks the end of the era where power banks relied on general lithium battery safety standards. Both portable chargers (power banks) and portable power stations must complete certification transition before April 1, 2027. This represents a significant elevation in market access requirements for the power bank industry and is a key initiative by national authorities to implement stricter source control for high-risk consumer products.

1. Background: Why a Dedicated Standard Was Needed
Power banks have become everyday consumer electronics with extremely high usage frequency. China is both the world's largest producer and consumer of these products. However, the longstanding absence of a mandatory national standard specifically for power banks has led to frequent safety incidents – overheating cells, falsely labeled capacity, and thermal runaway caused by inferior batteries have been repeatedly reported, posing serious threats to consumer safety and property.
GB 47372—2026 fills this regulatory gap. Unlike the previous approach that combined general standards (GB 4943.1 for IT equipment safety and GB 31241 for lithium batteries in portable electronics), this new standard is specifically tailored to the structural characteristics, usage scenarios, and failure modes of power banks. It establishes a more targeted safety technology framework with stricter requirements for cell intrinsic safety, intelligent management, and product traceability.
2. Scope and Product Classification
The standard applies to power bank products with a rated input voltage of AC 220V and/or DC not exceeding 250V, output voltage of DC and/or AC, and mass not exceeding 18 kg. Products are divided into two categories based on total battery energy rating, with differentiated management:
Portable Power Banks (Charging Banks)
Total battery energy rating ≤ 160Wh
Small charging devices for daily use
Must pass all basic safety tests
≤100Wh: Permitted in carry-on luggage
100–160Wh: Requires airline approval
160Wh: Prohibited from air travel
Portable Power Stations (Outdoor Power Supplies)
Total battery energy rating > 160Wh
Suitable for camping, emergency power, etc.
Must pass all power bank tests
Additionally required to pass thermal runaway test
Stricter safety requirements
Products exceeding 18 kg are not covered by this standard
Important Note: Devices with reverse charging functionality (such as smartphones and tablets) are not considered power banks and are not subject to this standard.
3. Five Key Technical Highlights
GB 47372—2026 strengthens safety requirements across five dimensions, building upon the general requirements of GB 4943.1 and GB 31241:
