These savings have been verified by an Independent Regulatory Compliance Laboratory and results showed that when the Energy Wizard plug in was used there was a reduction in energy consumption.
Still can't see how it will workThe destruction manual said:Find a mains socket you don’t currently

It probably is a PF correction device of sorts perhaps analysing the current/voltage ratio with a DSP then attempting to compensate with rapid current injection (isn't that the way some of the new fangled harmonic distortion PF correction devices work?) I can't quite get my head around it at the moment (need to draw it out on paper) because the current injection would use energy and I may be talking rubbish but I think you could achieve some correction in such a way but not much, in other words you might be able to PF correct small loads/small phase angles. In short, a waste of money.
I don't see how they can monitor current either, usually the measuring device has to be in series (or a wrap around CT) as opposed to being in parallel.
Not that pf correction will save a domestic customer any ££s as normal meters measure in Watts, not VA.
