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.
A separate compartment for the power cord allows you to hide this cord in the body of the device, which greatly simplifies storage and transportation. At the same time, such a compartment can also be supplemented with a device for uniform winding — it does not only provide additional convenience, but also protects the wire from bending and fractures.
