1. Mainstream big brands (Huawei / Xiaomi / Anker / Ugreen) all use integrated designs, relying on heat dissipation and shielding to solve EMI heat issues; 2. EMC separated design is the only technology that achieves physical isolation and solves the problem from the root. Integrated design (common among big brands

Summary of core differences: 1. Integrated type: Coil circuit "squeezed together", strong thermal interference EMI, barely meets standards relying shielding; 2. EMC separated type: Coil circuit "separated by a distance", fully isolated thermal / magnetic / EMI, naturally compliant, low temperature and high efficiency

Application scenarios for choosing between split-type and integrated-type technology? Choose integrated: pursuing compact, portable, low-cost, household / ordinary lowpower automotive products Choose EMC split-type: high-power, export, high-end automotive, commercial / industrial, multi-coil, high anti-interference requirement
