I use this charger:
I have used it with Note 8, 10, and 20 without issue. Not sure how fast the fast charging is on it since I have that disabled on my phone, and Rapid Charging kills batteries faster anyway, so. It has good reviews and has worked without fail.
As far as the complaints on how bright the light is, I have a tiny piece of black electrical tape covering the light, and only have a notification light on my phone (very dim dark red) when the phone charges so that it doesn't cause bright lights at night in my room. Check it out!
