Power Bank 3C Certification: Mandatory Safety Guarantee & Implementation Essentials

Editor:ESTL Category:Technical information Release time:2025-10-15 Click volume:9

With the popularization of mobile devices, power banks have become a daily necessity for modern people. However, the quality of power banks on the market varies greatly, and safety incidents occur from time to time. As China’s compulsory product certification, 3C Certification provides authoritative assurance for the quality and safety of power bank products. Guangdong Energy Storage Testing Technology Co., Ltd. will deeply analyze the importance and implementation key points of power bank 3C Certification for you.

Background & Scope of Power Bank 3C Certification

According to the regulations of the State Administration for Market Regulation, since August 1, 2023, lithium-ion batteries, battery packs, and power banks have been included in the management scope of Compulsory Product Certification (3C Certification). This means that power banks must obtain 3C Certification before they can be manufactured, sold, imported, or used in business activities.

The inclusion of power banks in 3C Certification management mainly stems from the frequent occurrence of power bank safety accidents in recent years. Statistics show that in 2022, there were more than 2,000 fire accidents caused by power banks nationwide, which seriously threatened the personal and property safety of consumers.

Core Value of Power Bank 3C Certification

1. Safety and Quality Assurance

3C Certification conducts strict testing on multiple indicators of power banks, including electrical safety, mechanical safety, thermal safety, and environmental adaptability. Products that pass the certification have their overcharge protection, short-circuit protection, overload protection, and other functions meeting national standards, effectively preventing safety hazards such as fire and explosion.

2. Necessary Condition for Market Access

Power banks without 3C Certification will not be able to be sold on e-commerce platforms, physical stores, and other channels. Major platforms have gradually started to verify the certification status of products, and uncertified products will face removal from shelves. At the same time, market supervision departments will also strengthen supervision and random inspection of power bank products in the circulation field.

3. Brand Reputation and Competitive Advantage

The 3C Certification mark has become an important reference for consumers to purchase power banks. Products with certification are more likely to gain consumer trust and gain an advantage in market competition. The certification process also helps enterprises identify product defects and improve product quality.

Key Testing Points of Power Bank 3C Certification

1. Safety Performance Testing

  • Electrical Safety Testing: Overcharge protection, short-circuit protection, over-discharge protection.
  • Mechanical Safety Testing: Drop test, crush test, impact test.
  • Environmental Safety Testing: Temperature cycle test, damp heat test, low-pressure test.

2. Requirements for Key Components

Key components of power banks, such as protection circuits, battery cells, and connectors, must meet relevant standard requirements. Among them, battery cells need to pass the testing of the GB 31241 standard, and protection circuits must have complete protection functions.

3. Marking and Instructions

The 3C Certification mark must be clearly marked on the product body, and a complete Chinese user manual must be provided, including key information such as rated capacity, rated voltage, and input/output parameters.

Suggestions for Optimizing the Certification Process

1. Preliminary Preparation

Enterprises are advised to consider certification requirements in the product design stage, select qualified component suppliers, and establish a complete quality management system. Prepare technical documents in advance, including product specifications, circuit diagrams, and a list of key components.

2. Selection of Testing Institutions

Guangdong Energy Storage Testing Technology Co., Ltd. has national recognized testing qualifications and rich certification experience. It can provide enterprises with comprehensive technical support and certification services to help enterprises pass certification efficiently and quickly.

3. Handling of Common Problems

Market Prospects & Compliance Suggestions

With the increase in supervision, the power bank market will gradually become standardized. It is expected that by 2025, the market share of power banks that have passed 3C Certification will exceed 90%. Production enterprises are advised to:

  • Start certification preparation work as soon as possible to avoid affecting product sales due to certification delays.
  • Establish a complete quality management system to ensure that products continuously meet certification requirements.
  • Pay attention to the update dynamics of standards and adjust product design and production processes in a timely manner.
  • Select reliable certification service institutions to ensure the smooth and efficient certification process.
