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.

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.

A small mesh (usually at the spout) that catches scale flakes and small particles to prevent them from getting into the cup when pouring. Its convenience lies in the fact that the filter can be quickly removed, rinsed under the tap, or cleaned with a soft brush without taking the kettle apart and without fussing with citric acid every time just for a few "crumbs" in the drink. Unlike non-removable inserts or "for show" filters, the removable option is easier to keep tidy, clogs less, and stays neat for longer, especially if the water is hard and the kettle is actively used at home or in the office. In practice, this is useful when you frequently boil water for tea/coffee or children's drinks: the filter does not completely solve the scale problem inside, but it significantly enhances comfort because there is less residue in the cup and the taste remains cleaner.
