StopWatt is a compact plug-in device marketed for U.S. homes as an electricity stabilizer that supposedly smooths voltage, filters so-called dirty electricity, improves power factor, and reduces energy bills when placed near the breaker box, yet independent tests and fact-checks consistently show it produces little to no measurable savings on residential electricity use and belongs to a family of rebranded low-cost “energy-saving boxes” often promoted with exaggerated claims.
