For mobile devices like the iPhone, we usually use CI Class B (Consumer Information Class B). This class is designed for consumer-grade electronics such as smartphones, tablets, and laptops. CI Class B ensures that the device meets safety, performance, and electromagnetic interference (EMI) standards for personal or home use. It helps make sure that the device won’t cause problems with other electronics and is safe for everyday users. So, for an iPhone or similar mobile devices, CI Class B is the correct classification.
