I experience pleasure and pains, and pursue goals in service of them, so I cannot reasonably deny the right of other sentient agents to do the same - Steven Pinker

A con trick.
The box MAY do nothing useful whatsoever.
It is implied that the power factor is improved, but firstly how does the device "know" what the existing power factor is ?
Secondly, a box that small and connected via a 15 amp 120 volt plug cannot make much impression on the power factor of a 50KW load as is implied.
And finally domestic electricity metering in the USA and also in the UK measures true KWH and not KVAH so there is no discernible gain in improving the power factor of domestic loads.

Yes, that may be a different brand, but I suspect that all these devices are broadly similar and that all are a con trick.Mr. Fox wrote:'BigClive' does a good teardown/explanation on them here, incase you wondered what's inside:

It is regrettable but understandable that sheeple buy these devices. What is more worrying is that large public sector organisations buy them.
Use in Schools is particularly worrying in that it gives children and their parents a belief that they work.
