As a simplified example I have an 8 lb transformer that is used as a 6-volt power supply for a carbon rod soldering station.
I plug in the transformer and note a 9 watt load even though the transformer is just sitting there grinning at me.
After an hour or so, the lamination's (the heavy square mass of steel wafers) has grown uncomfortably warm. I wouldn't want to have to fondle the transformer for very long.
This is yet another reason why I like those switching power supplies. They are far more efficient than a transformer type AC/DC circuit.
But to bring up another point, how angry does the converter get when the whip is put to it? Excessive heat is death to electronics. Whenever I tinker I read electronic component data sheets and wince. A 100 amp gizmo may be de-rated to 10 amperes max at higher temps.
My hearing has gone the way of crank handle starting, so fan noise is not a big issue with me. My gizmo projects usually whistle with F5 on the saffer simpson scale wind velocity. Absurdly huge heat sinks. I am a true cheapskate.
