I regularly use other chargers and have never seen this message. The galaxy charger is fast but that's because it has an output of 2A which is pretty high for a charger, most are around 1A.

I'm not sure I believe this is an optimised lead for charging though. I don't understand what this process is that is mentioned, that Samsung have employed that is any different to any other lead. It is just connecting a negative and positive terminal.

This said, yes impedance does have some impact but any half decent lead will be absolutely fine and any performance increase will be negligible if it's a standard length charging cable.
