OK now I have to correct myself. Still using the 100W Anker. If I plug in my Sony earbuds case into the USB-A port (case says input 5V 1A = 5W) then my laptop complains that the charger is slow. But the laptop only needs 65W so I don't know why it would complain .

edit: OK, I figured it out. It appears that the power supply works the way Anker's website says, which I didn't understand at first. The two USB-C ports do not each seem to be capable of 100W. Or at least, the device seems to prioritize them differently. If I plug into port 1 (on the outside of the three ports) and have something else plugged into the center USB-C port, the one on the edge shows to the laptop as 35W available. If I reverse the plugs and connect the laptop to the center USB-C port, it shows as a 60W port.
