For the enterprise, product quality is the life of the enterprise, especially electronic products. Take power, the quality of the product not only affects the performance and service life of the power supply, but also the safety of the power adapter. The inferior power supply can even cause fire and explosion, which seriously endangers people's lives.

Regardless of the quality of the power supply, it must be put into practical use to make the final judgment. But in the first option, that is, whether or not I qualify for this power supply, you must look at both certifications:

3C certification: Three Cs are: Chinese meaning: Compulsory certification in China. For the quality of the product itself, all products belong to the 3C certified products specified by the state and must obtain 3C certification. Nationally certified 3C products are mainly concentrated in electronic products and electronic products.

ISO9001, full name: ISO9001 quality management assurance system. It is non-state mandatory and belongs to the national recommended standard for the entire product quality management operation of the enterprise. A company that only passes the 3C certification can pass ISO9001 certification, otherwise, even if the application is not accepted.
