How It Works
Stabilizes The Power
With groundbreaking Electricity Stabilizing Technology (E.S.T.), StopWatt straightens the unstable electric current and delivers a constant, smooth output — improving the flow of power throughout your home for a more efficient system.
Eliminates Harmful Shocks & Surges
Using advanced capacitors, StopWatt eliminates harmful spikes of electricity, preventing damage to your appliances and electronics.
Reduces Dirty EMF Electricity
The built-in magnetic filter removes carbon from the electrical circuit, significantly reducing your exposure to harmful electromagnetic radiation (EMF/EMR) generated by your electronics, appliances, and dirty electrical system.
Get Started In 3 Easy Steps
Using StopWatt is quick, simple, and easy — stabilizing your electricity is as simple as 1, 2, 3.
Plug In Your Device
For one device, find a location as close as possible to your breaker box. For multiple devices, install each unit on a separate breaker — separate floors or opposite ends of the home work best.
Confirm It's Working
The green light illuminates when the device is plugged into an active outlet and begins to filter and stabilize the electrical current.
Filter, Stabilize & Save
The average home takes 2-3 weeks to stabilize the current and filter the EMF dirty electricity. Allow up to 6-8 weeks to start seeing full results.
Customer Reviews
Read what our customers have to say about StopWatt
"I'm so surprised by the amount we saved with these StopWatt devices… literally, you just plug them in and that's it! My wife was shocked when we got our first bill and we saved $35! It's only gotten better from there. We'll be customers for life."
"I don't usually write reviews, but I have to share some numbers. In the first month, we saved $33. The second month, $45. The third month, $52. Fourth month, $55. If that isn't a strong testimonial, I'm not sure what is!"
"If you're skeptical, I feel sorry for you. StopWatt has really made something special here. I'm not entirely sure how it works, but the savings are REAL!"
"I ended up buying 3 of these — one in the kitchen, one in the bedroom, one in the living room. After six months, we're easily saving at least $50 per month. StopWatt is a no brainer."

Questions? We've Got You Covered
Will StopWatt work in my state?
Absolutely. StopWatt is approved and helps stabilize electricity in all 50 states, including Hawaii and Alaska.
Will it work in my home?
Yes. StopWatt works in any home or business with electricity, including condos, offices, bungalows, and trailers — basically any space with electricity will benefit from having StopWatt installed.
Is it safe to leave StopWatt plugged in?
Absolutely. StopWatt is the only power factor device that is both UL approved 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's recommended to install 1 StopWatt for every 800–1,200 sq. ft. of space. Using more than recommended will not increase results.
What happens if the power goes out?
Not to worry — you won't have to filter the entire home again. As long as your StopWatt stays plugged in, it continues filtering as soon as the power comes back on.
Can StopWatt be used with a solar power system?
Yes, there are no safety issues using StopWatt with solar systems. The current version has not been extensively tested on solar-powered systems, so results may vary — the 60-day money-back guarantee covers you either way.
Is StopWatt legal?
Yes. Now that the Residential Energy Stabilization (RES) law has been passed, power factor devices and EMF filters such as StopWatt are legal in the USA.
What results can I expect?
Results vary based on home size, electricity usage, solar usage, location/climate, power company, and home age. Give StopWatt a full 2 months to filter electric pollution — if results aren't what you expected, contact us for a full refund.
Where do I place/install my StopWatt?
For one unit, install it somewhere central — often near the breaker box for convenience. For multiple units, install them as far apart as possible, ideally at opposite ends of the home, to maximize effectiveness.
Is there a warranty?
Yes, all orders include a 1-year standard warranty. If your StopWatt device breaks, is damaged, or stops working, contact support@stopwatts.com and we'll send a free replacement.
How long does it take to work?
Similar to an air or water filter, StopWatt takes time to fully filter dirty electricity — approximately 3–4 weeks for the average home. You're covered by the full 60-day money-back guarantee while you test it.
Does StopWatt work with 220V electrical systems?
Not at this time. StopWatt is currently only compatible with 110V North American electrical systems. A 220V version is in development.
What is the Power Saving Guarantee?
If after 60 days of using StopWatt you haven't saved enough in electricity to cover the cost of your purchase, you'll receive a 100% refund, including shipping costs — no questions asked.
