We made our money back in 4 months

I don't usually write reviews, but I have to share some numbers with you all… 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!

Frequently Asked Questions

Everything you need to know about StopWatt before you buy.

StopWatt uses Electricity Stabilizing Technology (E.S.T.) to smooth unstable electrical current, absorb harmonic waves, and buffer power surges using advanced capacitors. Its magnetic filter cleans dirty electricity in the 4–150kHz range, while reactive power compensation keeps voltage steady and reduces energy lost as heat. The result is cleaner, more efficient power flow throughout your home.

Absolutely. StopWatt is UL approved and RoHS compliant, meaning it has passed rigorous safety and environmental testing. It's designed for continuous use in North American 110V electrical systems and poses no fire or electrical hazard when used as directed.

One StopWatt unit is recommended per 800–1,200 sq. ft. For medium homes (1,200–1,500 sq. ft.), two units are ideal. For large homes over 1,500 sq. ft., three units provide optimal coverage. Using more than the recommended number of units will not increase results.

Results vary depending on home size, electrical infrastructure, appliances, and location. Typically, it takes 3–4 weeks to stabilize the current and filter dirty electricity, and up to 6–8 weeks to see the full benefits. Many customers report noticeable savings starting in their first month.

StopWatt is compatible with all 110V North American electrical systems, including homes, condos, offices, bungalows, and trailers across all 50 US states. It is not currently compatible with 220V systems. Installation requires no professional help — simply plug it into any active outlet.
