The powerful 1500-Watt heating element is hidden beneath the stainless floor of the unit, so it's never in contact with water, eliminating build-up of mineral deposits on it and allowing for easy cleanup. The revolutionary cordless design allows the kettle to be lifted from its base for convenient filling and serving. Handsomely constructed of high-quality brushed stainless steel, the kettle ensures years of service. The automatic shut-off, double boil-dry safety shut-off and lid-lock features guarantee safe use UL listed.
