On a complete side note - people can sometimes have some luck reading Cyrillic if they pretend it’s Greek. In the case above - phi, eta, nu - is roughly how you pronounce it - fen.
I did learn that фен can actually mean other kinds of hair dryer-like heat guns (from https://ru.m.wikipedia.org/wiki/Фен). I assume that’s what these folks used to heat various components.
In USA the default seems to be 1.85kw (https://www.amazon.com/s?k=hair+dryer) possibly because 2kw appliances are trickier for the 110v wiring.
P.S. I'm also surprised by the assertion that "the Russian for hairdryer (фен) happens to also mean a regular fan", as IMHO it does not, a regular fan would usually be called вентилятор, not фен. Фен means either a hair dryer or (as строительный фен) a heat gun for construction work.
