Comparison Panasonic NC-EG4000 4 L vs Mystery MTP-2453 700 W 4 L stainless steel

The power consumed by the thermopot (see "Type") in the heating mode, when the device maintains the temperature of the previously heated water. Manufacturers select this power in such a way that the device is guaranteed to be able to maintain the claimed temperature. Therefore, the only point that should be assessed by this feature is the general “voracity” of the thermopot in terms of electricity consumption. However, this mode requires relatively little energy, and the heating power does not exceed 200 W in the most voluminous models.

The temperature adjustment capabilities refer to the specific temperature values that can be programmed into the electric kettle. It's important to note that this refers to automatic adjustment, where the kettle turns off or switches to temperature maintenance mode once the desired temperature has been reached.

If this paragraph contains several options separated by commas (for example, “60 °С, 80 °С, 90 °С”), this means that this model has several fixed temperature options. However, there are also devices with smooth adjustment, which allows you to adjust the temperature in steps of 5 °C, or even 1 °C; for such devices, the entire adjustment range is indicated here, for example, "60 — 100 °C".

The greater the number of temperature setting options available in an electric kettle, the more versatile it becomes, allowing for precise selection of the optimal brewing mode for various types of drinks. Here is a simple table of recommended temperatures:

— white tea — 60 °C;
— yellow tea -70 °C;
— green tea — 80 °C;
— black tea — 90 °C;
— rooibos, hibiscus — 100 °C (up to boiling);
— baby food — 40 °C.

Of course, there are exceptions to such rules — depending on the specific type of drink. For example, some...varieties of green tea can be brewed at 90 °C.

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.

— Water supply button. The electric pump button is used to control the built-in pump in the kettle, which is responsible for supplying water to the spout. It is considered to be the most advanced method of water supply as it requires no manual effort from the user, can work with any container, and allows for accurate measurement of the required volume. Some models even provide automatic dosing where the electric pump dispenses a strictly defined volume of liquid with just the touch of a button. However, these supply systems are more expensive and require a power supply, which can be a disadvantage for some users.

— Hand pump. The mechanical pump with a manual drive is integrated into the lid of the thermopot and is operated by a large button. This type of pump is simple, inexpensive, and does not require electricity to function, which is beneficial in case of power outages. However, it is not very convenient since multiple presses are required to fill even a small cup, and it is difficult to accurately measure the amount of water dispensed. As a result, it is typically used in conjunction with more advanced systems rather than being the sole method of dispensing water.

— Cup pressing. This method is also known as the "cup-activated dispensing system". It uses an electric pump, similar to the button systems described earlier, but the switch for the pump...is located near the spout and is activated by the cup's edge instead of by hand. This makes it easy to dispense water by simply bringing the cup to the spout and pressing the switch with the cup's edge. However, this method is not suitable for certain types of cups such as soft plastic or paper cups, and holding the cup while dispensing can be inconvenient as the hot water can burn one's hand through the walls of the cup. Therefore, this method is often combined with a traditional serving button to provide users with the most convenient option for their situation.

The own display noticeably simplifies and facilitates the use of the kettle. Most often, this is the simplest single-colour screen, capable of displaying 2 — 3 figures and possibly the individual special symbols — however, in this case, more is not required. The display is especially convenient when selecting and controlling the heating temperature — after all, it is much more convenient to navigate by specific numbers than by simpler devices like colour indicators. Actually, the presence of a screen almost 100% guarantees that this model is also equipped with a thermostat.

Decorative lighting of the body or capacity of the kettle. It has mainly aesthetic value — it improves the appearance of the device. Sometimes it can serve as a kind of indicator, for example, change the colour when water is boiling.

The main material of the kettle.

Note that this paragraph primarily considers external material; the inner coating may differ from it. As for specific options, metal (usually steel), plastic and glass products are the most popular nowadays. More rare are glass with metal and ceramics (including porcelain). Here is a more detailed description of the different materials:

— Steel. Stainless steel is a popular material for kettles due to its strength, stylish appearance, and non-corrosive properties. It is available in a wide range of price categories. However, steel's high thermal conductivity may increase energy consumption and create a risk of burns. Steel is also opaque, so transparent inserts are necessary to monitor water levels. It is not suitable for teapots as it can give an extraneous aftertaste to the drink.

— Plastic. Plastic kettles are inexpensive and can be produced in various colors and transparency. They have low thermal conductivity, which reduces the risk of burns when touched. However, plastic is prone to scratches and can fade over time. Inexpensive plastic models may emit an unpleasant smell and taste when heated, but higher-priced models may use better quality plastic or have a metal lining to prevent this issue. Some high-end plastic materials are available b...ut cost more.

— Glass. Glass kettles have a visually appealing and transparent appearance, allowing you to easily monitor the water level without any special indicators. This is especially useful for teapots, as it enables the user to monitor the colour and saturation of the tea during the brewing process. Glass containers do not affect the taste or smell of the drink, which is highly beneficial for tea drinkers. Although glass is considered fragile, it is difficult to break such a container in reality. However, one of the downsides of glass containers is that any scale or contaminants inside the container are easily visible from the outside, requiring extra care to maintain their appearance. The thermal conductivity of glass is average, making it less prone to heat transfer than steel, but more so than many types of plastic. Therefore, touching a heated glass kettle should be avoided to prevent the risk of burns.
It should be noted that glass kettles often have parts made of materials other than glass. Usually, the top and bottom, as well as the handle, are made of plastic or a combination of plastic and metal. However, if these parts are mostly made of metal, the material is referred to as "glass with metal."

— Glass with metal. There are glass kettles that have metal top and bottom parts, with only a plastic insert in the lid for convenience purposes. These teapots are considered more advanced than the regular glass models that use plastic, as metal adds a sense of solidity and enhances durability. Also, since the contents of the kettle do not come into contact with plastic, the possibility of foreign tastes and odors is almost non-existent. However, such teapots are relatively expensive, although there are also affordable options available.

— Ceramics. Ceramics have a distinct advantage in terms of aesthetics as they offer a stylish appearance, making them an ideal choice for retro-style kettles or those with a classic design. Moreover, they are usually adorned with unique patterns and designs. Apart from their appearance, ceramic kettles do not affect the taste of the contents and provide excellent heat retention due to their thick walls. However, they are heavy and vulnerable to shocks, their opaque cases make it difficult to check water levels without opening the lid, and they lack water level indicators. Therefore, if appearance is a priority, ceramics can be an attractive option despite these drawbacks.

— Porcelain. Porcelain is a type of ceramic material that is highly valued for its prestigious appearance and is considered expensive. However, it is also fragile and requires delicate handling, which is why it is not commonly used in electric kettles.
