Does the Samsung 25W Power Adapter Fast-Charge the Samsung Galaxy S24 Ultra?
Yes, but the charger is the limiting factor — only 25W via USB PD, below the device's 45W ceiling.
Both sides speak USB PD, but the Samsung 25W Power Adapter's port tops out lower than the Samsung Galaxy S24 Ultra's 45W ceiling, so you get 25W instead of the device's absolute max.
