For the experiment with the thermal destruction of weeds, I took a cheap construction hair dryer for 989 rubles to test. They promised 2000 W and 650 °, alas, they turned out to be only promises.
The label funny says “110V/60Hz 220V/50Hz 2000W”. Anyone who does not guess that two different models are produced with this label will be very surprised. The following parameters are declared.

The hair dryer has two positions. In the first, with a mains voltage of exactly 220 volts, the hair dryer consumes 730 watts, in the second – 1450 watts. Almost a third of the power was “lost”.

In the first mode, the maximum temperature of the air coming out of the hair dryer is 280°C.

In the second – 430°C. And they promised 650!

The experiment with the thermal destruction of weeds failed; maybe the temperature is low or maybe it doesn’t work very well.
