Mobile power supplies are a popular category for overseas consumption electronics exports, with sales reaching many countries around the world. To break through market entry barriers in various countries, the CB certification is the key "passcode". As a global safety certification under the IECEE system, its results are recognized by 54 member countries, and enterprises can directly convert to local certifications in various countries by presenting the CB certificate, significantly reducing the cost of repeated tests and improving the efficiency of overseas expansion. This article simplifies and summarizes the core points of the CB certification for mobile power supplies, helping enterprises obtain certification efficiently.
I. What is CB Certification? Why is it necessary for mobile power supplies?
(1) Core Definition and Standard Basis
CB certification follows the principle of "one test, one certificate, global recognition", and is completed by the certification institutions (NCB) and laboratories (CBTL) of IECEE member countries. The core basis for mobile power supply CB certification is IEC 62133-2:2023 (lithium battery safety) and IEC 62368-1 (equipment safety), and after certification, it can directly convert to local certifications such as China's 3C, EU's CE, and Australia's SAA, only requiring the addition of a few local documents.
(2) Scope of Application and Core Judgement Criteria
All portable lithium-ion battery mobile power supplies (weight ≤ 18kg, including fast charging, magnetic attachment, etc.) are applicable; the core standard is: no risk of fire, explosion, leakage, controllable battery thermal runaway, and safety performance meets international standards, and electromagnetic interference meets the requirements.
(3) Core Necessity of CB Certification Processing
For overseas enterprises, CB certification is a basic compliance document, and its core value lies in four points: 1. Global recognition, saving 30%-60% certification costs and time; 2. Breaking through multiple country entry barriers, ensuring smooth customs clearance; 3. Enhancing market recognition in overseas markets, strengthening the trust of buyers and consumers; 4. Avoiding recall and penalty risks, meeting the requirements for entry into mainstream e-commerce platforms such as Amazon.
II. CB Certification Process for Mobile Power Supplies
(1) Essential Application Materials
All materials must be provided in English (with official seal and genuine validity), the core list includes: 1. 3-5 sets of qualified finished products (including charging cables); 2. Business license, ISO 9001 system documents (if not from the own factory, additional authorization documents are required); 3. English version of specifications, structure diagrams, BMS instructions, core component list; 4. Certification application form, consistency statement, test commission agreement (UN38.3 report can be shared); 5. Product photos, English warning labels, user manual.
(2) Complete Processing Flow (5 steps for efficient certification)
The regular cycle is 5-7 weeks (urgent 3-4 weeks), the process is as follows: 1. Selection: Choose an NCB institution and CBTL laboratory recognized by IECEE; 2. Case Opening: Submit materials and samples, and after review, officially open the case; 3. Testing: The laboratory completes all tests according to IEC standards, and if不合格， will provide rectification suggestions； 4. Issuance of Certificates and Reports： The NCB reviews and issues the certificate and report within 1-2 weeks； 5. Transferring Certificates： With the CB certificate， supplement local documents to quickly obtain the certification of the target country.
(3) Key Precautions
Core Avoidance Points： 1. Samples and production-ready products must be completely consistent， and core component changes require re-testing； 2. All documents must be in English， with accurate and error-free parameters； 3. Follow the latest IEC standards， confirm the requirements of the target country version； 4. Some countries (such as the United States) require additional testing， understand the local differences in advance； 5. Only choose official recognized institutions by IECEE， non-recognized reports cannot be transferred.
