Does StopWatt Really Work?
Whether StopWatt works as advertised is still a topic of debate.
The technology behind power factor correction is well known and is commonly used in factories, commercial buildings, and large industrial facilities. In these environments, improving the power factor can help lower certain electricity costs.
For most homes, however, the situation is different. Residential electricity meters usually measure the amount of electricity actually consumed, known as kilowatt-hours (kWh). In many regions, homeowners are not charged for reactive power. Because of this, many electrical professionals believe that plug-in power-saving devices may have little or no effect on a typical household electricity bill.
In simple terms:
- Power factor correction is a real electrical technology.
- In many homes, improving the power factor does not necessarily reduce the amount charged on the electricity bill.
- Any savings, if they occur, are likely to vary depending on the home’s electrical system and the types of appliances being used.
Customer reviews are also mixed. Some users say they noticed small improvements in power stability or electricity costs, while others report little or no measurable change.
Actual performance can depend on several factors, including:
- The appliances used in the home
- The condition of the home’s electrical wiring
- The quality of the local electricity supply
- How electricity is measured and billed by the local utility company
For these reasons, it is best to have realistic expectations. While StopWatt may provide benefits in some situations, there is no guarantee that every household will experience significant reductions in electricity bills.
