Samsung's Super Fast Charging comes in two speeds — 25W and 45W — and the real-world difference is bigger than with Apple's wattage tiers. Here's what actually changes.
Galaxy S23/S24 Ultra Charging Ceiling
Samsung's flagship Ultra models support up to 45W Super Fast Charging 2.0, while the standard S23/S24 models cap around 25W. Using a 45W charger on a standard S24 won't exceed its 25W ceiling — the phone itself sets the limit.
Real Charge-Time Comparison (0-50%)
- 25W charger on Ultra: noticeably slower than the phone's rated potential
- 45W charger on Ultra: reaches 50% significantly faster, taking full advantage of Super Fast Charging 2.0
- 25W or 45W charger on standard S23/S24: identical speed, since the phone caps at 25W regardless
The Cable Matters As Much As the Charger
Samsung's 45W Super Fast Charging 2.0 requires a 5A-rated cable — a standard cable can bottleneck the charger's full speed even if the adapter itself supports 45W.

Frequently Asked Questions
Will a 45W charger damage a Galaxy S23/S24 that only supports 25W?
No — the phone's charging chip only draws what it's rated for, regardless of the charger's maximum output.
Do I need a special cable for 45W charging?
Yes, a 5A-rated USB-C cable is required to unlock full 45W speed — a standard cable will bottleneck it.
