Yes, the x is a cap, but it is also a warning.

Anker's PowerIQ circuit seems to be wired to do exactly what you say, and looks like a modern CC/CV PWM LED lamp driver: switches to CV and lowers duty cycle to maintain intended max output once it crosses the voltage threshold (which could indicate a runaway thermal overload).

Apple's designs are baffling to me: the worst cables I've ever seen. Take the newest phone, the 11 Pro, and take their beefiest charger (I think this now comes with the phone? Is this the same one as the current iPad iterations'?)... and compare the stock cable to an Anker Powerline 2 or 3: an immediately visible difference in charge speed; and then do the same with a PowerIQ 2.0 charger w/ stock vs Powerline 2/3: an even BIGGER difference.

The hell, Apple?!
