Electricity bills can become expensive when a home uses air conditioners, refrigerators, washing machines, computers, televisions, and other appliances every day. Because of this, plug-in electricity-saving devices have become popular among homeowners looking for a simple way to manage energy use.
StopWatt Electricity-Saving Box is a compact plug-in device marketed as an electricity optimization and power-factor correction product. The company says it can stabilize electrical current, reduce electrical waste, filter so-called “dirty electricity,” and potentially help lower electricity costs.
