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."

Ok, in this case, it supports both - QC on the USB-A-Port and USB-PD on
the USB-C-Ports.

Many Chinese phones like Xiaomi or Huawei use QC and not PD.

As I already suggested: most likely the Bluetooth speaker you mentioned
does not support USB-PD at all since this is not that relevant on the
Chinese market (yet). It will just take what it gets and the USB-C input
is just for convencience, so it is easier to use a cable provided with
your QC compatible phone and the QC charger which usually uses a USB-A
connector for the carger side.
