We Bought & Tested The 5 Best-Selling Electricity Savers. Here’s Why StopWatt is Our #1 Pick
You can learn a lot about a company from the moment their product arrives—and StopWatt instantly stood out.
Instead of the usual plain packaging and a receipt, we were pleasantly surprised to find a handwritten thank-you note inside. It’s a small gesture, but one that speaks volumes—especially in a world where most tech brands overlook the personal touch.
Originally developed in 2019 as a university project by two engineering students in California, StopWatt quickly gained traction with investors. Despite rapid growth, the company has stayed true to its roots: putting people and planet first.
At a time when energy costs are climbing and sustainability matters more than ever, StopWatt has emerged as a smart, affordable solution for households looking to cut back on electricity waste.
From the thoughtful packaging to the company’s mission, every detail pointed to a quality product with purpose.
So we got to work.
Here’s what our testing revealed.
Our Test Results
Setup Takes Just 1–2 Minutes — No Tools or Expertise Required
StopWatt impressed us with its simplicity right out of the box. While it includes clear, step-by-step instructions, we found them almost unnecessary—the device is that intuitive.
All you have to do is plug the device into your selected electrical outlet. That’s it!
One of the Easiest Setups We've Seen — Clearly Designed With the Customer in Mind
StopWatt stands out as one of the most user-friendly energy-saving devices we’ve tested. Its quick, hassle-free setup reinforces that this product was built with the everyday consumer in mind.
With installation out of the way, it was time to put StopWatt to the test. We ran a series of evaluations to see if it truly delivered on its promises.
Here’s what we discovered:
Energy stabilizing – stabilizing the electrical current in your home can help prevent serious damage and tragedies, so we knew this was one of the most important features to test. We used an ammeter to see how StopWatt affected the electrical circuit in our office and were impressed with how much the spikes were reduced.
Cutting idle energy usage – many of our devices are sucking up electricity even if we’re not actively using them – this is called “idle mode”. We tested this by leaving StopWatt plugged in for a week and compared electricity consumption in our office. To our shock, the electricity usage was cut by 46%!
Device protection – one thing we don’t often realize is that our electronics are more sensitive than we could imagine. Items that are smaller, such as light fixtures and desktop gadgets, can be severely damaged by power surges or unstable currents. This is a significant feature of the StopWatt, as it can help improve the longevity of your tech.
Electrical fire prevention – we measured and compared the current quality before and after plugging StopWatt in. Surprisingly, the current in our office was verging on dangerous instability levels. This is a great investment for those living in older buildings, as wiring may be unsafe. StopWatt is an excellent way to feel safe in your home again.
StopWatt Outperformed Every Competitor in Side-by-Side Testing
We conducted the same rigorous tests across multiple leading energy-saving devices—and StopWatt consistently came out on top.
While its core features already make a strong case, we took it a step further. We evaluated additional performance areas that could be the deciding factors when choosing the right energy saver for your home.

Ease of Use
StopWatt Delivers Instant Efficiency — No Calibration, No Complications
During testing, one standout advantage became clear: StopWatt was by far the easiest to use. Unlike other energy savers that required manual setup or time-consuming calibration to your home’s electrical current, StopWatt worked instantly.
Just plug it in—and it gets to work immediately. If you value speed, simplicity, and hassle-free performance, StopWatt is the clear winner.

I got StopWatt for my uncle in Florida, who’s always been big on cutting down utility costs. The setup couldn’t have been easier—he plugged it in near the kitchen outlet and didn’t have to think about it again. A few weeks later, he called me in shock—his electric bill had dropped more than it had in years! Now he’s hooked, ordered three more, and even gave one to his neighbor. It’s rare to find something this simple that actually works.
Brian Thompson, Florida
I tried out StopWatt last month and was honestly shocked—my electric bill dropped almost instantly after I plugged it in. That was all the proof I needed! I grabbed two more for the garage and guest room, and the savings just kept growing. This month, my bill is nearly cut in half. I’ve already sent a few to my sister in Ohio and my buddy in Georgia. If you’re thinking about trying it, don’t wait—this thing is a game-changer!
Lisa Harper, Illinois
I was struggling big time this summer after getting laid off temporarily. The AC alone was eating up my savings, and I had to make tough choices just to stay afloat. Then I found out about StopWatt. I plugged it in, and within weeks, my power bill dropped enough to actually breathe again. Bonus—it's eco-friendly! I’ve always been the ‘save-the-planet’ friend, and now I can finally recommend something practical that doesn’t annoy everyone. Total lifesaver!
