A few points to note about kettles

1. About product certification
Electric kettle is a national compulsory certification product, in line with the certification standard has the "3C" logo.

When choosing, you must pay attention to see if there is a 3C logo, and do not buy if you do not have it.

2. About the thermostat
The thermostat is the core element of the electric kettle, but also determines the life of the electric kettle, the Strix thermostat or Otter thermostat imported from the UK is relatively good, with a service life of at least 12,000 times. The better domestic thermostat is the ABRAZO thermostat, which has a service life of more than 10,000 times.

A good thermostat can accurately control the temperature, and the service life is longer and more durable. The British strix thermostat or otter thermostat is preferred, followed by the ABRAZO thermostat.

3. About the material
There are several materials of electric kettles, let's talk about the precautions one by one:

● Stainless steel: There are several different grades and models of stainless steel, and the common stainless steel of electric kettles is 201, 202, 304. Different types of stainless steel have different nickel and chromium content, and the higher the nickel and chromium content, the stronger the corrosion resistance of stainless steel.

If the inner tank material of the electric kettle is stainless steel, food-grade 304 stainless steel is preferred. More resistant to corrosion and not easy to rust.

In addition, the inner tank is generally stainless steel, and the outer layer will generally have plastic or stainless steel for heat insulation and anti-scalding. There are also some low-cost only single-layer stainless steel. An electric kettle with multiple layers of protection will definitely have a better anti-scald design.

● Glass: The glass materials commonly used in electric kettles are tempered glass and borosilicate glass. Because the electric kettle often alternates cold and hot water, borosilicate glass is more resistant to cold and heat, and is not easy to burst.

If the body material of the electric kettle is made of glass, high borosilicate glass is preferred, which is more resistant to cold and heat and is not easy to break.

● Ceramics: The ceramics themselves are fired with porcelain clay at high temperature, which has relatively strong corrosion resistance. It is advisable to choose ceramics with smooth surface, high glaze finish and less porosity.

● Silicone: Some foldable electric kettle pots are made of silicone. It is advisable to choose food-grade silicone, and some use pacifier-grade silicone, which can also be used with confidence.

4. About the switch
The switch of the electric kettle is controlled by steam heat conduction, and some electric kettles have switches above the handle and some under the handle. The upper switch is directly above the water vapor heat conduction, while the lower switch is added with a steam pipe to conduct heat. Therefore, the following switches will be more reliable.

Good electric kettle with switch under the handle.
