A USB-C charger may make a buzzing or whining sound because magnetic components such as transformers and inductors can vibrate during high-frequency switching. The sound can be more noticeable at no load or light load when the charger enters burst-mode operation. A faint, stable sound may be normal, while loud or sudden noise combined with overheating or charging interruptions should be investigated.
