That article I noted above has a chart where they charged 3 phones with their own and each other's chargers and/or cables and monitored the current draw. There is no consistency, there are no labels, there are no apparent standards being used beyond the shape of the plug.the problem i had with USB-c is that depending on the device it can use a 45W+ charger. my HP elite X2 required 15V 3A to charge. qualcom quickcharge specs have 5V 3A , 9V 3A , 12V 3A , 15V 3A. also 20V 3A there are type A and B only type B do the 15 V and 20V.. this changes too fast .. i just read that with USB PD (power distribution) 100W is max over USB type C quick charge cables...
