Cordless designs and 360-degree bases enhance usability and ease of cleaning, while integrated limescale filters contribute to water purity and appliance lifespan. Ultimately, the most effective auto shut off electric kettles strike an optimal balance between rapid, consistent heating, robust safety protocols, and thoughtful design elements that enhance the overall user experience.
