What is StopWatt?

StopWatt uses advanced Electricity Stabilizing Technology to provide a smooth and stable electrical current output that improves power efficiency, reduces dirty electricity and electromagnetic interference (EMF), and protects electronic appliances from voltage fluctuations and power surges.

The device is designed with a simple plug-and-play approach. Just connect it to a compatible wall outlet, leave it plugged in, and it works continuously in the background. No tools, batteries, complicated settings, or professional installation are required.

Its compact, discreet form factor makes StopWatt suitable for a variety of settings including homes, apartments, offices, and trailers — anywhere a standard 110V outlet is available.

How StopWatt Works

A person uses a device to test an electrical wall outlet
Step 1: Test the Outlet

Before installation, users can test a wall outlet to see the current electrical environment. This baseline helps illustrate what StopWatt is designed to improve.

Step 3: See the Difference

After StopWatt is connected, users can re-test the outlet. The device filters harmonic waves, reduces dirty electricity, and helps smooth voltage spikes.

Internally, StopWatt uses capacitors and magnetic filters to filter and buffer harmonic waves and reactive power. It eliminates harmful voltage spikes, reduces dirty electricity by removing carbon from circuits, and provides surge protection to extend appliance lifespans.
