Electric Kettle supply from China and quality control service

In modern electric kettle the heating element is typically fully enclosed, with a power rating of 2–3 kW at 220V. In countries with 110V mains electricity, kettles may be less powerful (1–1.5 kW) to avoid drawing too much current and requiring a very thick supply wire.
In modern designs, once the water has reached boiling point, the kettle automatically deactivates, preventing the water from boiling away and damaging the heating element. A bimetallic strip thermostat is commonly used as the automatic shut-off mechanism.The thermostat is isolated from the water in the kettle and is instead heated by the steam created when the water boils, which is directed through a duct onto the bimetallic strip. This allows the thermostat to be coarsely calibrated, which in turn allows the kettle to function normally at a wide range of altitudes. A consequence of this design is that the kettle may fail to deactivate if the lid is left open, due to an insufficient amount of steam being ducted onto the bimetallic strip.

Electric wate kettle is also one of common products manufactured in China, supplier provides many different kettles with different prices, materials also included plastic, stainless steel, glass, metal, ceramic or other material, now you can see some famous brand in market like KitchenAid, Cuisinart, Mr. Coffee, Oster, Breville, Hamilton Beach, Delonghi, Black&Decker etc.
