Here is an excerpt from a recent test report on the S22 Ultra by Computer Bild: "Samsung calls the process "super fast charging 2.0" and apparently only supports it in optimal form when using the new "Samsung ET-T4510" power supply. When we plugged in the older 45-watt power supply TA-845 (also 45 watts) in the test, the S22 Ultra only reported "super fast charging" and predicted a total charging time that was several minutes longer than with "super fast charging 2.0" via ET-4510".
So apparently only the new version actually works, despite the identical technical data.
