Review on KKM 15W Qi-Certified Fast Wireless Charging Stand for iPhone 13/13 Pro/13 Pro Max/13 Mini, iPhone 12/12 Pro/12 Pro Max/12 Mini, iPhone 11/X/XS Max/8, Samsung S20 FE 5G/S21 Plus by Matthew Coste

I bought these after finding out that the Samsung Galaxy S21 Plus Ultra requires 15W for fast charging, not 10W. What counts when buying is the QC 3.0 Wall Charger (I found a 2-pack at Revain for less than $10). Together these two products create a really nifty fast charger. The stand itself is compact with a smooth vertical surface. The base is well rubberized to prevent slipping on smooth surfaces such as glass or laminated table tops. Unlike most of these fast chargers; This uses a USB-C cable to power the charger, meaning you don't need an additional micro-USB cable to power the charger. The soft green glow sounds intrusive, but it's not. He "breathes" to tell you he's working; and is a soft green glow rather than the bright blue or bright white light I was trying to avoid. The base of the charger has a small protrusion on the front to prevent the phone from sliding off. I have a SUPCASE style case on my phone and the charger works well through the case. I would buy it again and recommend it.
