Original 25W USB-C Super Fast Charging Wall Charger for Samsung Galaxy S21 Ultra, Charger Adapter with 3ft Type-C Cable - Black

25W USB-C Wall Charger + 3ft USB-C to USB-C Charging Cable

This item outputs up to a GENUINE 25w, does not top out at 15w like the majority of other listings that advertise 25w but only give you 15w.  Beware of other listings claiming 25w.

This adapter will activate 25W "Super" Fast Charging on devices that can utilize this feature.  Below is a partial compatible model list that can utilize the full 25w:

This adapter is an "auto switching" adapter, meaning it will also activate regular 15w "fast" charging on devices that can't utilize the max 25w output.   It will also do lower outputs such as 5W and 10W for devices that need them.  In short, your device will only pull the wattage it requires, no more.
