Very slow, but good quality
Color: 2White
It works as expected, but my phone says that it is a slow charger even when plugged in my fast charger brick. False advertising. Really wish it charged a little faster

Slow As a Turtle
Color: 2White
Super slow charging. After 10 minutes, my phone only charged 3%. I plugged my original charging cord into the same 65W charging block and after 2 minutes, it had charged nearly 10%.
