Suffice to say recently one of my type-C transplanted (cut and spliced from a cheap cable into an old 5V 2A power supply) male connectors stopped powering up my smartphone. Seems ( :???: ) that type-C male plugs are more prone to power negotiation failures than the (still) more standardized micro-B plugs, I think this somehow has to do with the small pins inside the type-C connector, and oxidation buildup.
I presume the inner pins are gold plated, after all that's what really matters.
Do you mean why did I splice the connector? I had a cheap 25cm type-C/A cable whose type-C connector I slashed, then I spliced it with my 5V 2A supply cable. The data lines were bridged. No rocket science:
Took a peek (with a flashlight) at the connector's innards, everything “seems” right. But no power. In fact, it still worked at times until I decided to clean it with denatured alcohol and a toothbrush, then it died.
The power negotiation thing may not be @#$%, I also had a few issues with micro-B but of course I use it a lot less now.
I also use a type-C gold plated cable very often, no problems with it.
Read that yesterday, Oli. And well, all I can say is I don't @#$%ing care, namely with all those premium loser brand smartphones. They can stick all these up their arses one by one, now that they're so big it would be fun.
I love standards but, given mankind's overall consciousness, DERP! Still, I have faith.
Concerning type-C DIY male connectors, my experience with cheap micro-B ones has been positive. So may be Suntaiho made some really piss poor cables, at least in the past (paid €2.05 for two 25cm units on sale, now discontinued).
