I own a S21 FE and currently charge it using a power bank as I have a 45W adapter. Given that the S21 FE supports a maximum charging speed of 25W, I am concerned about battery damage from using the 45W adapter. Is it safe to use, and is it recommended?
Recommended to use original charger (Samsung charger) . If it is 45W, AFC charger will automatically change to max 25W according to the device's need. It can go lower from 25W to 15W if the device gets warm during charging as a safety measure.
