Three things to understand before ordering:
The 1-year device warranty covers defective or damaged units separately from the money-back guarantee. Contact support@stopwatts.com for both.
Per the manufacturer: plug the device into a standard 110V wall outlet. The green LED confirms the device is active. For one unit, a central location near the breaker box is recommended. For multiple units, place each as far apart as possible in the home. The manufacturer recommends leaving the device plugged in continuously — unplugging may reverse the filtering effect over time. No tools, no professional installation, no maintenance required.
What is StopWatt?
StopWatt is a plug-in home device designed to stabilize electrical current, filter what the manufacturer describes as 'dirty electricity,' and provide reactive power compensation. According to the manufacturer, it is UL approved and RoHS compliant. It is compatible with standard 110V North American electrical systems only. It does not require any installation — simply plug it into any standard wall outlet.
How does StopWatt work according to the manufacturer?
According to the manufacturer, StopWatt uses Electricity Stabilizing Technology (E.S.T.) to smooth electrical current fluctuations, advanced capacitors to buffer electrical spikes, and a magnetic filter to reduce electromagnetic frequencies in the 4–150kHz range that the manufacturer refers to as 'dirty electricity.' The manufacturer recommends allowing 3–4 weeks after installation for the device to stabilize the electrical environment, and up to 6–8 weeks before evaluating results.
How many StopWatt units do I need?
According to the manufacturer's guidelines: one unit for small homes (800–1,200 sq ft), two units for medium homes (1,200–1,500 sq ft), and three units for large homes (1,500+ sq ft). For multiple units, the manufacturer recommends placing them as far apart as possible — ideally at opposite ends of the home — rather than clustering them together. Using more units than recommended is not expected to increase results.
Where should I install StopWatt?
For a single unit, the manufacturer recommends a central location, often near the electrical breaker box. For multiple units, the manufacturer recommends placing each unit on a separate breaker, as far apart as possible within the home — for example, on separate floors or at opposite ends of the building. No tools or professional installation are required.
Is StopWatt safe to leave plugged in?
According to the manufacturer, StopWatt is safe to leave plugged in continuously. The manufacturer states the device is UL approved and RoHS compliant. The green indicator light confirms the device is active when plugged into a working outlet. The manufacturer recommends leaving the device plugged in continuously rather than unplugging it, as disconnecting the device may reverse the filtering effect over time.
Does StopWatt work with solar systems?
The manufacturer states there are no safety concerns with using StopWatt alongside solar systems. However, the manufacturer notes that the current version has not been thoroughly tested with solar-powered electrical systems, and results may differ from non-solar installations. The 60-day money-back guarantee covers purchases where results do not meet expectations.
What is StopWatt's money-back guarantee?
StopWatt is backed by a 60-day money-back guarantee from the date of delivery. If not satisfied within 60 days, contact the support team at support@stopwatts.com to request a refund and receive return instructions. All refund requests are handled by email. The manufacturer also includes a 1-year standard warranty covering defective or damaged devices.
Is StopWatt compatible with 220V systems?
No. StopWatt is currently only compatible with 110V North American electrical systems. It is not compatible with 220V systems used in many international markets. The manufacturer states they are developing a 220V version for future release.
When will StopWatt ship?
Orders ship within 24–48 hours of confirmation, excluding weekends and holidays, via USPS. Standard shipping takes 5–7 days. Express shipping via FedEx 2-Day or USPS Priority Mail takes 2–3 days. All orders include tracking information sent via email. StopWatt ships from within the USA — no customs fees or additional charges apply for US customers.
