Power
Electrical power consumed by the device during operation. A more
powerful appliance spends less time cooking to readiness; at the same time, the high consumption of electricity is often offset by the speed of cooking (in other words, the device simply does not have time to "eat" a lot of energy). However, such a device will also cost more. Therefore, it makes sense to specifically look for such a technique mainly in cases where “every extra second matters” — for example, if a toaster is bought for a cafe or diner where you need to cook quickly and in large quantities.
Also note that a device with a large capacity will inevitably require a higher power.
Number of products
The maximum number of individual products that can be cooked in the appliance at the same time.
For toasters, this parameter corresponds to the number of standard rectangular pieces of bread that fit into the device. Accordingly, if the size of the blanks used differs from the standard, then the capacity may be more or less than the claimed one.
If we are talking about a waffle iron, cake-pans or other device of a similar design (see "Type"), then the number of products is usually indicated by the number of notches on the working surface. In this case, note that the larger the capacity, the smaller the size of each product (especially since the working surface area for different models does not differ so much).
