I got it from ebay dealer: cnfu7527
No fancy box for this charge, just an envelope and a plastic bag, but it did include a USB cable.
The fake QC specifications.

The QC marked output can deliver about 2.6A

And slightly less at 24V supply

The 2.1A marked output is exactly the same.

And also when they are used in parallel.

There was no problem running 1 hour with 2.1A load.
The temperature photos below are taken between 30 minutes and 60 minutes into the one hour test.

I could easily pull the front off, but getting the circuit board out I broke a capacitor!

On this side is the two capacitors, the inductor and a led.

The "fuse" is a zero ohm resistor. The switcher (U1: HC8813) is a 2.1A chip with 10V to 30V input range and support for cable compensation.

Being a 12V device there is no need to test with high voltages.
Conclusion
This charger is a fake, it do not in any way support QC. With that said, it is an acceptable 2.1A charger, it is without any auto coding and has some noise.
