@carlsbad2 my Power Plant Premier doesn’t have a watt meter, unfortunately.
I did the test today. I didn’t have anything plug in, and after 10 hrs, it becomes too hot to touch. The heat is build up gradually. At about 5 hrs, it gets quite warm but I can still place my hand on it. But now, I cannot touch it for more than 5s. And once again, there is no load on it, no equipment is plugged in. I don’t have a IR thermometer, but I search on the internet, it says 60 C is normally too hot to touch. Given I can still lay my hand for 5s or so, I estimate it to be not much higher than 60 C. Maybe 60-70 C? I think based on all the reply and what I read on the internet, this is still not normal, right?
