Identical wattage ratings don’t guarantee identical real-world speed — supported power profiles, cable quality, and how quickly the charger ramps up all affect the actual charging curve, not just the peak number on the box.

Practical note

When comparing chargers, treat the printed wattage as a starting point for research, not the full picture — cable quality and negotiation behavior matter just as much.
