Review on Kmasic 2-in-1 Charger: Versa 2 Charging Stand & Cell Phone Dock by Elizabeth Edwards

I bought this and it has successfully charged both my Fitbit (Versa 2) and iPhone (11 pro max). It worked for about 2 weeks and then stopped charging my phone and a few days later it stopped charging my Fitbit. I returned it for a new one because it has been working for 2 weeks so I thought I'd try a new one. This worked again for about 2 weeks. My Fitbit kept charging, but when I put my iPhone in it showed that it was charging, but was it actually draining my phone's battery in some way every time I used it? I don't even know how it happens, but it was draining my phone's battery. I woke up one morning after "charging" it all night and my phone was dead. I really wanted it to work because it's so convenient. Unfortunately that doesn't work.
