Re: Recognizing PD QC chargers

There are so many charger bricks out there that I wonder if there's a good

tell if a charger has PD or QC output?
 
Generally I assume any charger with a USB-C port is probably one or the
other or both but I can't read the microprint on the side of most of them.
 
Is there a way to tell other than getting a microscope to read that print?

There are testers you can buy which will talk to the PD or QC control
signals and tell you what it claims to do.  Look on Amazon, Aliexpress, etc.

Not a recommendation, just an example:
https://www.amazon.com/Voltage-Multimeter-Detection-Capacity-Measurement/dp/B0BS2ZS813/

If the microprint tells you the voltages (5/9/12/15/20/48V) you can infer
the PD capability from that, but to do that you'd need to read it.  Try
taking a photo when lit from an oblique angle, which should pick up the
embossing, then zoom into the photo.
