Yes, a higher-wattage USB-C charger can charge a compatible Mac.

Apple says a Mac that charges over USB-C can use a USB-C power adapter or display that supports USB Power Delivery. A higher wattage than the Mac's recommended adapter is not, by itself, a reason to reject the charger.

Check the charging standard

Wattage is only one part of compatibility. Confirm that the Mac charges over USB-C and that the adapter supports USB Power Delivery. Apple also says third-party power adapters and displays should meet the applicable safety standards. Use a suitable USB-C cable and inspect it for damage.

Apple recommends using a power source that provides at least the minimum wattage specified for the Mac model. A lower-wattage adapter may charge slowly or may not keep up while the computer is under heavy load. Check the Mac model and the adapter's label rather than guessing from the connector shape.

What “higher wattage” means

The adapter's wattage rating describes its maximum available output under supported conditions. It does not tell you whether the adapter follows the right charging protocol or whether the cable is suitable. Choose reputable, standards-compliant equipment and do not use a damaged, counterfeit, or unusually hot adapter.

Scope

This guide covers USB-C charging on compatible Mac laptops. Older Macs that use MagSafe or another connector need model-specific guidance. Other laptop brands may specify different charging standards and limits.
