There is no large transformer, the style is the same as the data cable, and it is much lighter than the original charger. It is absolutely suitable for home travel and necessary for charging.

CB certification introduction

The CB system (IEC system for conformity testing and certification of electrical products) is an international system operated by IECEE. The certification bodies of each member country of IECEE test the safety performance of electrical products on the basis of IEC standards. The test results are the CB test report and CB The test certificate is a system of mutual recognition among the member states of IECEE.

Up to now, 66 certification bodies in 51 countries and more than 270 CB laboratories under their jurisdiction have participated in this mutual appointment system. The purpose is to reduce international trade barriers due to the need to meet the certification or approval criteria of different countries. IECEE is the abbreviation of the International Electrotechnical Commission's electrotechnical product conformity testing and certification organization. After the enterprise obtains the CB certificate from one of the certification bodies, due to the mutual recognition agreement, it can no longer carry out repeated tests. It can be converted into safety certification certificates of other member states by only doing report audits and supplementary tests or national difference tests.

The necessity of CB certification

It is the basis of the CB system that the product safety test results of electrical and electronic equipment are accepted globally. After the test is successfully completed, a CB test certificate and corresponding CB test report will be issued for the product. The two documents together constitute A pass, the manufacturer can apply for the national certification of any certification body in the country or region participating in the CB system, usually no additional testing is required.

CB certification product range

At present, the CB system covers electronic game devices, test equipment, power supply cables, capacitors and parts, lighting, household appliances, protection devices, transformers, office and IT equipment, and medical equipment, with a total of 180 products in 14 categories.

CB certification body

If the USB charger and car charger have obtained the CB test certificate, since the CB test of the product is tested in the country, compared with foreign CB testing institutions, the CB test of the product in the country will save more costs, as long as the product CB certification certificate can be obtained by handing over the CB test qualification report obtained domestically to the CB certification body, which saves certification costs and certification time.
