A USB fan is a miniature electric fan applied to the USB interface of a desktop computer or a notebook computer. In today's market, such small fans are generally divided into two types: rechargeable USB type and battery-powered type. The small USB charging fan is simply connected to a computer or power bank through a USB cable to supply power and then work normally. This type of fan is mostly used in offices. However, in general, if such products want to be listed on domestic e-commerce platforms, they need to provide third-party quality inspection reports.

What is a quality inspection report?

The so-called quality inspection report refers to the safety and performance inspection of the product, which has successfully entered other platforms such as Tmall, Jingdong Mall or supermarkets, or is a reference standard for consumers. According to the three-level standard (national standard, ministerial standard and enterprise's own standard), carry out quality assessment, make basic evaluation, and analyze the reasons for qualified or unqualified quality. This is the main body of the QA report. Only a laboratory authorized by China Metrology Certification (CMA) + China National Accreditation Service for Conformity Assessment (CNAS) is required, and the quality inspection report issued is valid.
