Certified Cells for China's New Power Bank Standard Pass 100 Models — 110 Cells From 20 Battery Makers
2026-09-24 · Compiled by Best IT Parts from public industry reporting
With China's GB 47372-2026 safety specification for mobile power supplies moving through implementation, cell certification under the standard continues to expand. An industry tally now counts 103 3C certificates covering 110 cell models from 20 battery companies, a clear step up from the small number of early approvals.
Capacity coverage has widened at both ends. The 5000mAh and 10000mAh classes remain the two most concentrated segments and still represent the mainstream choice for power bank designs, where they account for the bulk of current design wins, but certified products now run from a 730mAh cell up to 20000mAh parts.
Package format is dominated by pouch cells: only 2 of the 110 certified models use a cylindrical format, one in the 26700 size and one in 40135, and both are lithium iron phosphate. Recurring footprint sizes include 126280, 706074 and 676076, with 126280 appearing most often in 10000mAh-class products.
The practical effect for buyers and power bank makers is a wider sourcing window. With more suppliers, capacities and can sizes now covered by the same certification framework, cell selection is shifting from a shortage of certified options toward matching format, capacity and chemistry to the target enclosure, power rating and assembly process. The pouch majority also reflects how these packs are built: flat cells can be shaped around an enclosure and stacked to hit a target capacity, which is harder to achieve with round cans.
