Physical insulated electric kettle W970
Electric kettleJoyoung Company Limited
This insulated kettle uses innovative insulation materials instead of vacuum insulation technology which is expensive and less efficient. The insulation can maintain 45-degree insulation for nine hours without power, making it an energy-efficient way to keep water hot. The real-time temperature display has a built-in battery that displays the temperature even if not on the power base, and the lid has a built-in mechanism that prevents water from spilling if the kettle is dropped.
