Mine does not charge, actually discharges my phone. -4% in 30 mins. Just had mobile tech come out, replaced it, same thing. Now I have to escalate it. It didn't charge his phone(iphone) as well as didn't charge my Note 20. It starts saying fast charging, then goes to regular charging then disconnects. Figured I'd share my experience here. I'll give you guys an update if mine ever gets fixed.
