StopWatt gives your home a smooth, stable electrical current — cutting waste, protecting your appliances, and lowering your power bill.
Offer expires at midnight · Ships from the USA
Unstable electrical current and "dirty electricity" quietly waste power and wear down your appliances, every single day.
Voltage spikes and fluctuations force your appliances to work harder than they should.
Electrical "noise" on your home's wiring silently drains extra energy every month.
Power surges and shocks slowly damage the electronics and appliances you rely on.
With Electricity Stabilizing Technology (E.S.T.), StopWatt straightens your unstable current into a smooth, constant output — for a more efficient home.
Provides a constant, smooth electrical output throughout your entire home.
Advanced capacitors absorb harmful spikes before they reach your electronics.
A built-in magnetic filter cuts your exposure to harmful electromagnetic noise.

"I'm so surprised by the amount we saved. Literally, you just plug it in — my wife was shocked when we got our first bill and saved $35!"
"In the first month we saved $33. Second month, $45. Third month, $52. Fourth month, $55. If that's not a strong testimonial, I don't know what is."
"If you're skeptical, I feel sorry for you. StopWatt has really made something special here. I'm not sure exactly how it works, but the savings are real."
"I put one in the kitchen, one in the bedroom, one in the living room. After six months we're easily saving $50 a month. It's a total no-brainer."
