How do those “power saver” boxes work, if it all, to reduce household appliance electricity usage?
In: Technology
They have a blinking LED, and that makes people think it’s actually doing something. They work in the sense that they make money for the people selling them.
They claim to improve the power factor, and without going into detail about what the power factor is, it’s enough to know that
a) the power factor doesn’t matter at all in residential buildings
b) the amount of actual circuitry contained within the device is too small by several orders of magnitude to do what it’s claiming to do
It’s just a blinking light.
