I used a USB-C power meter to compare the power delivered through this cable to the included Samsung Note 10+ cable. This cable matches the performance of the included Samsung cable (approx. 24W). The E-Marker chip makes it possible. A minor complaint (like some other reviewers) is that the cable is a bit stiff. However, this makes the cable strong. The connector snaps into my charger and phone with the right amount of force.
