The power consumed by the kettle during operation is actually the power of the heating element installed in the device.

Two working moments depend on this parameter: heating intensity and electricity consumption. On the one hand, the high power of the heater allows you to quickly heat up a certain volume of water and saves time. On the other hand, the power consumption of such a device will also be appropriate. The wattage of a kettle's heater typically does not have a significant impact on electricity bills since the energy consumption required to heat a given volume of water remains the same regardless of the heater's power rating. However, there may be certain issues related to electrical connectivity. For example, if the wiring is weak or the fuses are improperly sized, the operation of a high-power heater may cause power outages. Additionally, devices with a power rating greater than 3500 W cannot be connected to a regular electrical outlet and require a specific power format. Consequently, even the largest thermal pots, which typically have a capacity of 10 L or more, are rarely equipped with heaters more powerful than 3000 W, since this power rating is sufficient for their intended use and can be connected to a standard electrical outlet.

A device that allows you to estimate the amount of water in the kettle without opening its lid. Most often the water level indicator has the form of a scale applied either to the transparent wall of the container, or to a transparent insert in an opaque wall. In any case, this function allows you to measure the volume of filled water quite accurately, and not just determine it “by eye”. This possibility is especially important for models with open coils (see "Heating element"), in such devices, a mark on the indicator is usually applied to the minimum allowable water level.

The ability to completely remove the lid of the kettle. Such a possibility is not of particular importance during regular use, however, it provides additional convenience if the kettle needs to be washed from the inside — a removable lid, unlike a traditional non-removable one, will not hang on the fixture, hit your hands and create other discomforts. On the other hand, there is a certain risk of losing this lid, so this feature is not common.

Kettles (see "Type") in which the lid opens at the touch of a button. This opening is faster and more convenient, and often safer than the traditional way (grab the lid and pull it up): the lid can get quite hot when the kettle is in operation, and long contact with it is fraught with burns. And although the button can also be placed on the lid, a short press is enough to activate it, and even in such cases the risk of getting burned is minimal. On the other hand, opening the lid with a button complicates the design of the kettle and reduces its reliability.
