In the last few years I have purchased a pressure cooker and an air fryer. They both waste electricity by having an off light. Furthermore they act like red nightlights and my kitchen has an eerie red glow at night. What is the actual purpose for off lights besides to waste electricity?
The ultra tiny amount of electricity is… Well you probably would never notice it on your bill.
But yeah it can be annoying having it there. I guess the purpose is to tell you that it has power available if you need it
Yes those small LED indicator lights use around 10-20mA of current at like 3V which is only 0.06W of power.
