To determine if a USB-C Apple MacBook Air charger cord supports high-speed charging, you can check the following specifications:
Compatibility with your MacBook Air model: Ensure the cable is compatible with your specific MacBook Air model, as older models might have different charging requirements.
Maximum wattage supported: Look for cables that support higher wattages, such as 60W or higher, as these are indicative of fast charging capabilities.
Compatibility with USB PD: USB PD technology allows for faster and more efficient charging. Ensure the cable explicitly mentions support for USB PD.
