USB C to DC cable

[avimakkar]

Does anybody has idea how this cable works? I bought it from AliExpress it's actually a good quality type c to dc 4.5x3.0 cable. I have been using it with my ravpower 61 watt pd charger for two weeks now without any hitch.

I am not sure how it works because normally power delivery chargers require a handshake to set a voltage to work but my laptop doesn't (hp Pavilion x360 2019) supports pd.
