I wasted money on a different power stabilizer last summer that did absolutely nothing. I was hesitant to try StopWatt, but its build quality is much better. The other brand got hot to the touch, but this one stays cool. My appliances seem to run much smoother with this unit.

About the StopWatt

What is StopWatt, and what is it actually meant to do?

StopWatt is a compact, plug-in electricity-saving device. it is designed for people who want to reduce their electricity consumption, avoid power surges, and extend the lifespan of household appliances.

This device helps stabilize electricity, reduce dirty electricity, and promote efficient energy usage within residential electrical systems.

This device is the size of a phone charger that can be connected to any standard wall outlet. There is no wiring to do and no app to install, and the setup is simple enough that you won't need a technician. Plug it in, the green light comes on, and you leave it there.

StopWatt is compatible with any home, office, bungalow, or trailer that operates on a 110V North American electric system.

Once plugged in, the device begins working automatically to filter and stabilize the electrical current flowing through the home’s wiring system.

It works through Electricity Stabilizing Technology - capacitors that absorbs spikes and release energy back in a smoother form. This is on-the-spot reactive power compensation.

A single unit can cover roughly 800 to 1200 square feet, which covers most households. Larger homes should use two or three, placed on separate breakers or at opposite ends of the house, with the first as close to the breaker panel as possible.

Plug in and leave it

Under a minute, no tools. A green light confirms it's running.

110V homes only

Built for North American systems. Not compatible with 220V

One unit per 800-1,200 sq ft

Larger homes use two or three, on separate breakers

Three people, three reasons they kept wearing it.

5.0/5 ★★★★★

I doubted one little plug could fix the terrible wiring in my old farmhouse. However, it did drop my monthly usage by about ten percent. It takes up a whole wall outlet, which is mildly annoying, but the surge protection alone makes it worth keeping.

5.0/5 ★★★★★

I thought plug-in energy devices were a complete scam. My power company raised rates again, so I finally bought StopWatt in pure frustration. But it actually works. I plugged it in near my breaker panel. My fridge runs quieter now, and my last bill was noticeably lower than the same month last year. Highly Recommended!

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! And it's only gotten better from there… We'll be customers for life."

How a box this small does anything at all

There is no setup to get wrong - the whole install is one socket and a green light. What takes time is what comes after, so give it a few weeks before you judge the results.

It works on the circuit

Plug it into any socket and it joins that breaker's circuit - so it's working on the supply every outlet there shares, not on one appliance. Best spot is the socket nearest your breaker panel. A second unit goes on a different breaker.

Capacitors absorb the spikes

When a fridge compressor or an AC unit kicks in, it pulls hard and the current jumps. The capacitors take up that excess and feed it back into the circuit in a smoother, flatter form, instead of letting the spike travel on.

A magnetic filter takes out the noise

Chargers, LED bulbs, dimmers and TVs all push high-frequency noise back into your wiring. That's what "dirty electricity" means. The magnetic filter targets it.

Reactive power gets corrected on the spot

Motors - fridges, washing machines, air conditioners - pull current slightly out of step with the voltage. Some of it flows back and forth doing no work, and the circuit carries it anyway. Evening that out is power factor correction.

110V North American systems only

One unit per 800–1,200 sq ft

60 days to send it back

What this is not. StopWatt is not a guaranteed way to cut your bill. Home meters charge for real energy in kilowatt-hours, not power factor, so any effect on what you pay is modest and varies house to house.

Benefits

Here are some of the benefits of StopWatt

No install

Nothing to fit, nothing to maintain

StopWatt is easy to setup. No electrician, no rewiring, no holes in the wall. Nothing to clean out or swap later either. It simply goes in a socket and stays there.

Renting

Works fine if you don't own the place

If you are living in a rental then permanent electrical work is not an option. This device needs no permission and changes nothing about the apartment.

Older homes

Built for wiring that isn't new

Older circuits fluctuate more and rewiring a house get things messy - about costs, too much work etc. If your lights get dim when you turn on AC, that is exactly the kind of house this is aimed at.

Low risk

Sixty days to decide

You just have to pay one time, there is no additional subscriptions. You can use it for 60 days form delivery and if it is not for you, simply sent it back.

Scales

Add more as the house needs

A single unit of StopWatt covers 800 to 1200 square feet. For bigger places you should use more units, spread across separate breakers. Nothing to reconfigure.
