Three pieces of evidence help you assess an adapter-based charging solution: physical connector and communication compatibility, permitted power and safety certification, and warranty, regulations and long-term maintenance.

The difference between GB/T and CCS2 is not just the plug shape — the adapter solution also involves communication and power.
