StopWatt is a compact, plug-in device that stabilizes electrical current, reduces dirty electricity, and protects your appliances — all while helping lower your monthly electricity bills.
Your plug-and-play power optimization solution
StopWatt is a plug-and-play power optimization device designed to improve electrical current stability in homes and small offices. Using Electricity Stabilizing Technology (E.S.T.), it straightens unstable electric current to provide smooth power output, reduces reactive power waste, and filters out harmful dirty electricity — all without any rewiring or complex installation.
Simply plug it into any standard 110V outlet, and the device begins working immediately. Its advanced capacitors buffer power surges, while a built-in magnetic filter reduces electromagnetic radiation (EMF) throughout your home's electrical system. No maintenance is ever required.
