Question about Samsung Galaxy S25 Ultra

To use Fast Charging, the USB-C to USB-C cable does not necessarily have to be from Samsung, but it should fulfil the same specifications as the original cable. A cable with a high current transfer capacity (e.g. 3A) is required to achieve the full charging power of up to 45W. It is important that the cable is compatible with the USB-C standard and provides the necessary safety features to ensure safe and efficient charging.
