It depends. The electricity consumption of the Thermomix ® TM5 will vary according to which levels and temperatures you use. Generally speaking, the power needed corresponds to the speed and the force needed to make the knife spin. So, using the same ingredients, the quality of the chopping or mixing will increase as the speed increases, as will the power consumption.
When the Thermomix ® TM5 is switched off, its electricity consumption is 0 watts, even while it’s still plugged in.
The Thermomix ® TM5 doesn’t have a so-called standby mode. It is either switched on and in operating mode, or completely switched off.
