Water tank
The volume of the water tank provided in the coffee maker; for turkish electric coffee pot (see "Type"), this paragraph indicates the actual working volume of the turk.
The larger the tank, the more coffee you can make without refilling the device; on the other hand, a large capacity, respectively, affects the dimensions, weight and price of the device. Therefore, manufacturers select this parameter in accordance with the general level of the coffee maker and the features of its intended use. So, you rarely have to make more than two cups of coffee at the same time, and 300 – 400 mL for such cases is usually more than enough for home use. And for use in a coffee shop or restaurant, where coffee is made often and in large quantities,
large-sized devices are produced, the volume of which is already calculated in liters; recommendations for choosing the volume of a coffee maker for professional use can be found in special sources.
Max. cup height
The highest height of a cup (or other container) that can be used with a coffee maker — a larger tank simply does not fit under the spout.
This parameter makes it easier to choose compatible cookware. The smallest value of this indicator is about 75 mm, and in some models the allowable cup height reaches 160 mm and even more. For comparison, the classic "demitasse" coffee cup used for espresso is about 60 mm high, a standard 200 ml disposable cup is just over 90 mm, and a 400 ml ceramic mug (standard proportions) is about 120 mm.
Power consumption
Power consumption of the coffee maker. Usually, this indicator is comparable with the power of the heater installed in the device.
This parameter is selected by the manufacturer, taking into account other performance characteristics (type of device, tank volume, additional functions, etc.), so that the coffee maker can effectively cope with its tasks. Therefore, in fact, power is of secondary importance: it is worth deciding first of all on other practical points, and only then look at power when choosing. In general, a more powerful coffee maker (ceteris paribus) will quickly cope with the preparation of coffee, but it will also cost more.
