These cables lie to you about how fast they are charging your devices. It's very easy to tell it's lying because it's saying that it's charging at 120w when the charger it is connected to and the device are both not capable of anything close to that. Picture shows it being measured at ~11w while it reports at 117w. I bought two cables, one with usb-c ends and another with one side being usb-a and both do the same thing. The whole point of the little display is to get live information on charge rates, it's useless if it tells you 120w regardless of what is actually happening.
