→Samsung requirements and fit questions
Does Galaxy S25 need a 25W or 45W charger?Samsung specifies 25W wired charging for the base Galaxy S25 in its S25-series documentation. The S25+ and S25 Ultra are the models associated with Samsung's 45W charging path, so buying a 45W adapter for the base S25 does not make it a 45W-charging phone.
→Does Galaxy S25 Ultra support 45W wired charging?Yes. Samsung's S25-series documentation specifies the 45W wired charging path for Galaxy S25 Ultra, with the power adapter sold separately. Actual charging speed still varies with battery level, temperature, cable capability and active use.
→Does Galaxy S26 Ultra support 60W wired charging?Yes. Samsung states that Galaxy S26 Ultra Super Fast Charging 3.0 increased wired charging power from 45W to 60W and can reach about 75% in around 30 minutes under Samsung's conditions.
