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%.

Great & very convenient charger, only one issue
Color: 2Black
This charger wound up being everything I hoped for - it charges a Galaxy S26 fast and works with a wireless charger compatible phone case. Despite all this, I'm taking a star off for the fact that *you have to buy an aftermarket converter* for it, because for some ridiculous reason, its cable end isn't a USB type A (which your previous phone's converters and probably many of your home's outlets use), but requires a 30W (no less) USB-C. So, there goes another $10 for the converter. Actually you'll probably want to buy two, for at least two rooms at your home, so there goes another $20.
