I realise this technology is ‘questionable’ in its claims (EG: It says it stores mains electricity for up to 10 seconds), but exactly what sort of components would it have inside? Could it be worth buying just for hacking the parts? It says 18KW, so it could have something fairly beefy inside.Worth a punt?

 

Hello,

It looks like a scam to me.
Perhaps some capacitors and a diode or somthing is inside to let the leds burn.

It's likely to have nothing but a couple of wires inside. With only two prongs, it's hard to see what could connect to it for any putative savings.

 

It looks to me like it would simply light up the LEDs and consume more power. How could anything like that plug into a wall and save that much power? I'd say it's definitely a scam.

 

"optimises the voltage and current demands"

It's just another one of those power factor correction capacitors in a box. It's probably a few uF, that seems typical.

 

Is not the power factor a thing that causes problems mostly for the power companies, as they do not get paid for the energy. But also that it may result in system instability and severe overvoltage fluctuations.

 

Hey if you really want to find out, buy it and crack it open...


however, given the size of that thing the 18kW metric just doesnt add up.
