Weird cable with USB A connector with 5 pins (discuss.tchncs.de)

Hello, I recently bought a USB A to C cable and it is pretty weird. It is a USB A to USB C cable, seemingly USB 2.0 but the A connector has 5 pins, the 4 pins of USB 2 and what looks like pin 7 of USB 3.0 so in the middle of the back row, the other pins of USB 3.0 are not there and the plasting moulding only allows for that one pin (moreover the USB type C end looks like it only has the few middle pins so it's probably 2.0). The weirdness continues because when connected to a USB power supply the led on the USB C connector lights up but it can only charge simple devices like flashlights or things that generally just accept 5V, anything with fast charging capabilities gets no output. I am probably going to test it with breakout boards and eventually even disassembly it and maybe replace the connectors but in the meantime does anyone have any explanation?

P.S. I will make a follow up post (or an update here) when I open it up, with photos of course.

Hey fair enough. If you are really concerned about what it if you could always reach out to the manufacturer
