Everything you need to know about StopWatt

StopWatt uses Electricity Stabilizing Technology (E.S.T.) and advanced capacitors to straighten unstable electrical current, absorb harmonic waves, buffer electric current shocks, eliminate harmful surges, and filter dirty electromagnetic radiation (EMF) from your home wiring.

Yes, absolutely. StopWatt is UL approved and RoHS compliant, meaning it meets strict safety and environmental standards. It is safe to leave plugged in continuously and requires no maintenance. The device is designed for North American 110v standard voltage.

For a single device, plug it into an outlet as close to your breaker box as possible, or in a central location. For multiple devices, place them at opposite ends of your home to maximize the stabilizing and filtering effect across the entire electrical system.

Yes, StopWatt is safe to use with solar power systems. However, effectiveness may vary depending on your specific solar setup, as it has not been fully tested across all solar configurations.

StopWatt offers a 60-day money-back guarantee. If you're not satisfied, you can return the device within 60 days for a full refund — no questions asked. Additionally, a 1-year warranty covers free replacement if the device breaks or stops working.

For smaller homes or apartments, one device near the breaker box is often sufficient. For larger homes, using 2-3 devices placed at opposite ends of the property maximizes the stabilizing and filtering effect. Using more devices than recommended does not increase results beyond the optimal coverage.
