Fast Charging Capability: The Tesla CCS to Tesla Adapter promises Level 3 fast charging up to 250KW, significantly reducing charging times compared to Level 2 AC charging. However, some users report overheating issues that reduce the speed to as low as 44KW.

Compatibility Issues: While marketed as universally compatible with most third-party fast charging stations, several users report it did not work at EV Go or Chargepoint stations. This could limit its usefulness depending on your local charging infrastructure.

Build Quality: Made from aircraft-grade aluminum alloy with anti-corrosion gold-coated connectors, the adapter appears durable for long-term use. Some users confirm it works well without issues.

Convenience Factor: When functional, this compact adapter provides Tesla drivers with more charging flexibility beyond the Supercharger network, especially useful for road trips or areas with limited Tesla chargers.

Final Verdict: This adapter shows potential but has inconsistent performance. It may work well for some users while failing completely for others. If you frequently use CCS chargers, it might be worth trying - but purchase from a retailer with a good return policy in case of compatibility issues.
