Heating power
It is the power consumed by the device in water heating mode. Usually, it is the operating power of the heating element.
This parameter is directly related to the heating performance (see above): a high heating rate inevitably requires appropriate power. Also, the power consumption of the device depends on this parameter. However, it is worth noting that after the end of heating, the device switches to the temperature maintenance mode and requires much less energy. In other words, the heater consumes the specified power not constantly but occasionally, as needed.
It is also worth mentioning that in models that work only for heating, this indicator also describes the maximum power consumption of the entire device. And, if there are two modes (heating and cooling), the total maximum power consumption corresponds to the sum of the powers of both modes.
Cooling power
It is the power consumed by the device in water cooling mode. In other words, this is the power required for the operation of all elements of the cooling system — a compressor or a converter with a fan (depending on the type of cooling, see above).
This parameter is directly related to the cooling performance (see above): a high cooling rate inevitably requires appropriate power. However, with the same power, compressor systems are more performant than electronic ones. Only models with coolers of the same type can be compared in terms of power.
Also note that the cooling system does not consume this power constantly, but only when necessary. So, at room temperature of the water in the "cold" tank, it turns on at full capacity, and when the desired temperature is reached, it switches to its maintenance mode, which requires much less energy.
In cooling-only models, this figure describes the maximum power consumption of the entire device. And, if there are two modes (heating and cooling), the total maximum power consumption corresponds to the sum of the powers of both modes.
Cup holder
A cup holder is a special stand or compartment for storing glasses. Note that almost all coolers and purifiers can install a cup holder, but here it means that such a device was originally provided in the kit or device design — this eliminates the need to purchase a
cup holder separately.
Usually, cup holders are designed for classic disposable plastic cups with a capacity of about 200 mL. At the same time, the holder, usually, can accommodate a whole stack of such cups — about two dozen or even more. The convenience of this function is that the cups are always near the device, and the user does not need to worry about which container to pour water into and carry cups or other vessels with him. The main user's job is not to forget to replenish the supply of cups on time.
