evnchnI continued testing it turned out that changing the cable to ORICO HTK-10 helped.
If so many devices can quick charge while Asus fast charge, suspect faulty Quick Charge handshake. Please try and see if you can transfer data to your computer using the cable you used for quick charging other phones. I suspect broken data pins if Asus fail to transfer data, and broken power management chip if Asus can transfer data.
bbbr/Android - PSA to anyone using USB c phones that stopped charging for no reasonJust saw this Reddit post recently. Follow instructions with some common sense to see if the problem lies there. No way 1 cable can charge while another one cannot, they are the same physically and electrically.

However, I do not quite understand why quick charging does not work with Asus Zenfone 6 + cable Orico KAC-05-RD.
The producer writes "ORICO KAC-05 5A Aramid Fiber Braided Type-A to Type-C Charge & Sync Cable 50cm" (I have several such cables.)
Now Quick Charging is working with Blitzwolf/Lenovo charger.
Thanks for your help.
