It purpose is to correct the power factor. They are using the flurosent light or motor as the load example. Which is bad in power factor.
That is why you see the Amp lower after switch ON.
But your home is not charge according to power factor. TNB charge you in Kwh.
That's why this thing have no effect to your bill.
Don't waste your money in this device. And those have it, better throw it to rubbish bin.
For large power users like factories, pF is important because if we do not correct the pF using capacitor bank, measured in kVArh, TNB will charge us penalty.
For average home users, the savings is negligible as TNB do not charge you according to kVArh, but in kWh (TNB adsorb the pF 'losses')
Like what ozak says is true, no difference to your electricity bill.
