The power consumption of an exhaust fan can range from a few watts to over 100 watts, depending on its size, capacity, and efficiency. For instance, a small bathroom exhaust fan may consume around 30 to 50 watts, while a larger kitchen exhaust fan may use up to 150 watts. It is essential to check the manufacturer's specifications for the exact power consumption of a specific model.
