The "KVAR Power Factor Optimizer" claims to reduce your electricity bill by using capacitors to alter the power factor of the electricity being consumed in your home. It further claims that an improved power factor will extend the life of electrical devices, help electrical motors run more efficiently, save light bulbs and eliminate static interference. But this is not correct for most home owners!

The "Dolphin Smart Electricity Saver" also known as "Electricity Saving Box" and also known as the "Flexi Power Saver or Flexi Powersaver" claims to reduce your electricity bill by 30% though correcting the power factor in your home. This is a misleading scam!

AC power flow has the three components: Real Power, measured in Watts; Apparent Power measured in Volt-Amperes; and Reactive Power, measured in reactive Volt-Amperes (var). The Power Factor of an AC electric power system is defined as the ratio of the Real Power to the Apparent Power.
