Power levels
The number of power levels (adjustments) provided in the device.
The more levels provided in the design (with the same maximum power) — the more precisely you can adjust the heating to your preferences. On the other hand, the abundance of adjustments affects the complexity and price of the device, despite the fact that there is not always a need for this. So, for electric sheets (see "Type"),
2 – 3 modes are quite enough — intensive for preheating and one, less often two workers. On the other hand, the opposite situation occurs —
6 or even more power levels.
Fast heating
The presence of a
fast heating mode in the device. In this mode, the heating element operates at increased power, thereby reducing the time required to reach operating temperature. After entering the mode, the heater power usually decreases automatically, but this point needs to be specified separately. Also note that auto switch-off of fast heating and auto-switch of power level are different functions, see below for the last.
Operating time
The operating time is the time until the device auto-shutdown. Therefore the time during which a sheet or blanket works on heating. There are models with an adjustable shutdown timer, which allows you to set the required time for the device to automatically turn off.
