New 3C Power Bank Rules: Key Changes & Compliance Guide
2026-01-09
On August 15, 2025, China's updated 3C (CCC) certification regulations for power banks officially came into effect, introducing comprehensive upgrades covering market access, production control, and traceability supervision. Combining the core content of the regulations, this article breaks down the key points to help consumers and buyers select safer, more reliable products.
1. What is a 3C-Certified Power Bank?
A 3C-certified power bank refers to a portable charger that has passed China's mandatory CCC (China Compulsory Certification).
Its core functions and values include:
1.3C certification = official safety certification for the Chinese market;
2.Meets strict electrical, thermal, and structural safety standards through rigorous testing;
3.Ensures the reliability of key components such as Battery Cells, BMS (Battery Management System), and enclosures;
4.Obtains official market access qualification for legal sales in China;
5.Serves as an important quality reference for global buyers and facilitates international logistics customs clearance.
2. Why Did China Update the 3C Power Bank Certification?
Severe Safety Situation
In recent years, fire and explosion accidents caused by low-quality power banks have occurred frequently. Most problematic products suffer from substandard battery cells, lack of protective circuits, and false capacity labeling. The old standards can no longer effectively regulate market chaos.

Accelerated Technological Iteration
The rapid development of fast-charging technology, coupled with the popularization of new functions such as multi-port output, wireless charging, and PD protocols, has made it necessary to update testing methods and safety requirements.

Standardize Market Order
Raising the access threshold through mandatory certification promotes the industry's development towards scale and standardization, protecting consumers' legitimate rights and interests.

3. Core Changes of the New 3C Regulations
More Accurate Capacity Labeling
The deviation between the actual output energy (Wh) and the labeled value must be ≤ ±10%. False labeling is strictly prohibited, and non-compliant products cannot obtain certification. The instruction manual must include clear warning labels and risks of improper use.

Strict Control of Battery Cell Quality
Only Grade A lithium-ion cells with traceable batches are allowed. Recycled, mixed, or downgraded cells are prohibited. Enterprises must provide aging data and cycle life records for each batch of cells.

Enhanced BMS Testing
Comprehensive testing of functions such as overcharge/over-discharge protection, overcurrent/short-circuit protection, and temperature monitoring.

Upgraded Structural Safety
Products must pass drop, extrusion, and deformation tests. Enclosures must be made of fire-retardant materials such as ABS/PC, with internal insulation design to prevent short circuits caused by external forces.

4. Conclusion
The new 3C regulations significantly improve the safety and reliability of power banks through strict control of battery cells, enhanced testing, and structural upgrades. For enterprises, although higher production costs are required, it will promote product upgrading. For consumers and buyers, risks of low-quality products can be avoided by verifying 3C certificates, battery cell batch records, fire-retardant enclosures, etc. In the future, compliant 3C-certified power banks will become the market mainstream, ensuring safe use while driving the high-quality development of the industry.
