Pinsheng has not passed Apple's MFI certification, and there may be several reasons:
1. Product compatibility issues: Apple devices have strict technical specifications for interface types, rated voltages, maximum currents and other related parameters, and Pinsheng's products may not be able to fully meet these detailed requirements, resulting in abnormal operation of the product in the actual application process or posing potential harm to the equipment.
2. Quality and process problems: Apple has put forward high requirements for the manufacturing process selection, raw material screening and performance index setting of accessories, and some of Pinsheng's products may still have insufficient performance in these aspects.
3. Product design and production problems: Some of Pinsheng's products may have design defects, lagging production processes and even loose quality control, and many other problems, which may sometimes become one of the important obstacles affecting the products to pass Apple's certification.
In order to solve such problems quickly and effectively, Pinsheng should focus on improving its product development and design capabilities, further improving product compatibility and overall quality, and strengthening quality supervision to ensure that the performance and quality of each product meet Apple's strict standards.
