Ans: The watt specifications that you see on the label are indicators of the power of the device. When you say an induction cooktop with 1800 watts, it means that the appliance will convert more quantity of consumed electricity into heat a 1200-watt device. Since it is an appliance with higher watts, it heats more faster and eventually takes less time to cook. However, you should note that an 1800-watt device induction will consume more power than the one with 1200 watts.
