That adapter just provides the mechanical connection between the USB device and the power source jack - so your 12V supply still needs a converter. The fleabay description states:
TypeC Female Jack Plug to Mini USB Male Power Charger Adapter
Use any 5V, Multi-voltage charger to power your device
Note:You must make sure power supply is correct voltage for your device.
This adapter DOES NOT come with any power supply - It is an adapter tip ONLY.

I think this is what you are after - just cut the jack from your PS and make sure to observe polarity of the 12V connection wiring:
