The certification is different in each country and region.
IEC International Electrotechnical Commission
3C certification CCEE means China Electrical Certification, which is certified by the China Electrotechnical Commission
The difference between CCC power supply and CCEE power supply :
1) CCC certification includes CCEE, CCIB (China Import and Export Quality Certification), and EMC (Electromagnetic Compatibility Certification), while CCEE does not have EMC (Electromagnetic Compatibility Certification), so the radiation of CCC power supply is smaller than CCEE power supply.
2) Because the CCC power supply contains a PFC circuit, the power factor is higher. In other words, using a CCC power supply saves more power.
3) The quality of CCC power supply is better than CCEE power supply
