Charged all three cables, but cannot fast charge. I figured I could live with slow charging as the cable length was very convenient, but during one day my charging port wouldn't stop saying USB-C was plugged in/disconnected persistently, even when unplugged, and wouldn't leave my screen switch off because of persistent reminder. I did a factory reset and used the old cable and the problem was gone. Well a week later I foolishly decided to try these cables again and immediately found the problem again. I think the three I got were just defective as most of the reviews here seem to be good but be careful.
