Well - it does not tell, if this charger is USB-PD or QC or both.

Thanks for taking a look at the image as the spec was complicated for me.

I think it has both based on the product description here
https://www.amazon.com/Charger-GOLDNEXT-Foldable-Block-Cable/dp/B0BYNQBSQ5
"Our 67W 3-port charger features dual USB-C (PD3.0) and 1 USB-A (QC3.0)
ports."
 

How would you describe those super complicated charger specifications
sufficient to explain why the USB-C ports don't charge the bluetooth?

 
I would recommend to get a charger where the supported standards are
documented by the manufacturer. Having a list of USB port combinations
and the possible power output for the combination does not help at all
in this matter.
 
However the list itself is not that "complicated". For example:
 
USB-C1+USB-C2:45W+20W (65W Max)
 
So if you connect one device to USB-C1 and a second device to USB-C2,
the port USB-C1 provides up to 45W and USB-C2 up to 25W.
 
USB-C1+USB-A:45W+18W (63W Max)
 
So if you connect one device to USB-C1 and a second device to USB-A, the
port USB-C1 provides up to 45W and USB-A up to 18W. And the line below
explains, how the 18W on USB-A is achieved - using 5V at 3.6A which is
5*3.6 = 18 Watts

Thanks. They had all those extra sections on the charger in the photo
showing what the output was which I will use Irvanview OCR plugins to get
the output which is below for the super complicated specifications I see.

Here's the Irfanview OCR plugin output - which I checked for accuracy.

Is that the PD & QC spec that the advertising says it is?
