How It Works
Stabilizes the power
With groundbreaking Electricity Stabilizing Technology (E.S.T.), StopWatt can stabilize unstable power output and deliver a constant, even performance. This improves power flow throughout the home and leads to a more efficient system.
Eliminates harmful power surges and overvoltages
By using advanced capacitors, StopWatt can eliminate harmful power spikes and prevent damage to devices and electronics.
Reduces dirty EMF electricity
The magnetic filter removes carbon from the circuit, helping to significantly reduce your exposure to harmful electromagnetic radiation (EMF/EMR) from electronic devices, appliances, and polluted power lines.
GET STARTED IN 3 SIMPLE STEPS
Using StopWatt is fast, easy, and straightforward.
Stabilizing your power is as simple as 1, 2, 3...
CONNECT YOUR DEVICE
Find a location for the device as close as possible to your circuit breaker. For multiple devices, install each device on a separate circuit breaker. Separate floors or opposite ends of the house work best.
ENSURE YOUR DEVICE IS WORKING
The green light turns on when the device is plugged into an active outlet and begins filtering and stabilizing the power.
FILTER, STABILIZE, AND SAVE
In an average household it takes 2 to 3 weeks for the power to stabilize and EMF currents to be filtered. It may take 6 to 8 weeks to see the benefits and results.

Svenja Esser, Naumburg Verified Customer
Not many things in life are child's play... StopWatt is one of them.
“So well, I eventually bought three of them. One I placed in my kitchen, one in the bedroom and one in our living room. After a few months I can safely say we are saving at least €50 per month. StopWatt is child's play. Want to save money each month? Buy a few and you're ready.”5/5 Verified Review

Common Questions
Does StopWatt work in Germany?
Absolutely. StopWatt is approved and contributes to stabilizing the power supply across the country.
Does it work in my home?
Absolutely. StopWatt is approved and contributes to stabilizing the power supply across the country.
Is it safe to leave StopWatt plugged in?
Definitely. StopWatt is the only power factor device that is both UL‑certified and RoHS‑compliant, making it the safest power factor product on the market.
How many units do I need?
To achieve maximum EMF filtering results, it is recommended to install 1 StopWatt per 74–111 m² area. Using more than the recommended number does not yield better results.
What happens if the power goes out in our house or office?
Don’t worry. You don’t need to re‑filter the whole house if the power goes out. Remember that during a power outage no new dirty EMF power enters the house. As long as your StopWatt remains plugged in, it will continue filtering when power returns.
Can StopWatt be used with a solar system?
There are no safety concerns. The StopWatt device can be used with solar installations. Our new version was launched this year and hasn’t been thoroughly tested in solar‑powered electrical systems, so we’re not sure how effective StopWatt will be with solar. There is a possibility you won’t see the same results as with a non‑solar system. Note we offer a 60‑day money‑back guarantee if you’re not fully satisfied.
Is StopWatt cool?
Yes! With the passage of the Energy Supply Stabilization Act (RES) for residential buildings, power factor devices and EMF filters like StopWatt are finally allowed in Germany.
What results can I expect with StopWatt?
Results vary based on many factors, including house size, power consumption, solar usage, location/climate, utility, house age, and many others. We ask customers to give StopWatt two full months to filter electrical pollution in the 4‑150 kHz range (the most harmful dirty electricity). If results after two months don’t meet expectations, contact us for a full refund. No questions asked.
Does StopWatt help the environment?
Yes. By making your household power flow more efficiently, you consume less electricity and save energy.
