After I ruined a few batteries I stopped using fast chargers, good old 5V 2A is good enough if you plan accordingly, the only thing those fast chargers are good for is for powering a soldering iron or some other thing that needs a lot of power but not for charging smaller batteries. I got a charger from Aliexpress with 8 USB ports, 6 type A, 2 type C, up to 30W for port and 100W total, has a screen showing the V, A, W for every port, got wireless charging on top but I don't use wireless charging.
