They do not run the risk of boiling dry as they turn themselves off once at boiling temperature by using a thermostat.

HISTORICAL DEVELOPMENTS
The kettle has been an appliance that has been evolving for thousands of years. The earliest kettle discovered was from Mesopotamia, dating back to around 3000 BC.

Also, during the late 50’s and early 1960’s, more manufacturing technology was developed, which in effect lead to a significant increase of mass production. Along with an increased economy, this meant that kitchen appliances become drastically cheaper and became essential in everyday life. From there the plastic polypropylene took over in the 1970’s, which in effect lead to the jug shaped kettle becoming the dominant type of electric kettle. More features were introduced such as a water level gauge and detachable filters, until in 1986 the invention of the cordless kettle was introduced.
