Verdict: Don’t buy Pro Power Save expecting a lower electricity bill. The reviewed sources provide no credible independent evidence that it delivers the dramatic household savings advertised. We also found no verified Consumer Reports test or endorsement of the product in those sources. Power-factor correction is a real technique in some commercial settings, but that does not show that a small plug-in device will cut a home’s electricity use.
What Pro Power Save claims to do
Pro Power Save, also marketed in similar-looking listings under names such as Pro Power Saver, Stop Watt, Power Saver Pro and Watt Saver, is sold as a small plug-in device. Advertising may say it stabilizes voltage, cleans “dirty electricity,” improves power factor, protects appliances or reduces wasted current. Some sellers promise substantial bill reductions; similar marketplace listings have claimed savings of 20–35%, while other promotions have gone as high as 90%. These are seller claims, not independently verified results. Similar listings do not establish that every product or seller is the same company.
The key question is not whether a gadget changes a voltage reading or has a light that turns on. It is whether the home uses fewer billable kilowatt-hours (kWh) while doing the same work—and whether that reduction is large enough to show up on the bill.
What the evidence says
Lead Stories found no credible independent evidence supporting claims that this kind of device can cut an electricity bill in half. Science Feedback examined Pro Power Save in the context of a wider family of similarly promoted plug-in products, including products sold under other names, and reported misleading product claims and celebrity associations.

There are also complaints and consumer reports in the Better Business Bureau’s Pro Power Saver profile and its customer-review page, as well as BBB Scam Tracker report 751037, report 780439 and report 683424. Reports describe disputed savings claims, dissatisfaction with the product, refund difficulties and concerns about pricing. One report compares a claimed three-unit price of $157 with visually similar units said to be available for about $16 for three; that is an individual report, not a verified universal price comparison. Another describes advertising of “up to 90%” savings and a customer who said their bill increased. These are consumer allegations, not controlled electrical tests. The BBB says it does not endorse products or businesses.
Taken together, the sources raise substantial concerns about the advertising and provide no sound basis to expect the advertised savings. They do not establish that every unit sold under a similar name has identical components, or that every specific unit has been laboratory-tested.
Why power-factor claims don’t prove residential savings
Homes using alternating current draw both real power, which does useful work, and reactive power, associated with some electrical loads. Power factor describes how effectively supplied power is converted into useful work. Motors and some commercial lighting can contribute to a low power factor. Utilities may charge certain commercial customers for demand or reactive-power issues, so engineered power-factor correction can matter in those settings. The U.S. Department of Energy’s utility-bill guide discusses power factor in the context of large motors and industrial facilities.

That is different from an ordinary U.S. household bill, which is generally driven primarily by kWh consumption. A capacitor or similar component at one outlet does not make a refrigerator, air conditioner, water heater or other appliance need dramatically less energy to perform the same task. Correcting power factor in a particular commercial installation is not evidence that a universal plug-in box will reduce a home’s metered energy use by 50–90%.
Likewise, “voltage stabilization” and “dirty electricity” are not proof of savings. Household voltage is supplied through utility and service equipment; a small outlet device is not equivalent to a whole-home regulator. Even if a gadget altered some electrical waveform characteristic, that would not automatically mean fewer billable kWh. A credible claim should specify what is measured, the test method, the baseline, the number of samples and independent results—not just a technical-sounding description or a testimonial.
Is there a real Consumer Reports review?
We did not find a verified Consumer Reports test or endorsement of Pro Power Save in the sources reviewed. Nor should the available BBB complaints or independent fact checks be described as an official Consumer Reports verdict. Pages and advertorials that place “Consumer Reports” beside terms such as “reviews” or “complaints,” or use “as seen in” badges, do not establish that the publication tested or endorsed a product. Look for a genuine article on the publication’s own site before treating that attribution as real.

Advertising red flags to watch for
- Extreme savings promises: Claims of 20%, 50% or 90% off a household bill should be backed by independent, household-level kWh measurements. A testimonial or voltage reading is not enough.
- Celebrity associations: Science Feedback reported misleading associations with figures including Elon Musk, Joanna Gaines and Leonardo DiCaprio. Verify endorsements on the person’s official channels rather than trusting an advertorial image or quote.
- Fake-news styling and urgency: A page presented as a news report, with countdowns, “secret” energy-company claims or assertions that utilities are suppressing a device, is a reason to slow down and verify the seller.
- Unverifiable technical reports: Ask for the laboratory, test protocol, measured kWh reduction and results for the exact model—not a generic diagram or unexplained certificate.
- Testimonials without controls: One lower bill may reflect milder weather, fewer people at home, different appliance use, rate changes, billing dates or an estimated meter reading.
- Unclear seller and return terms: Check the legal seller, physical contact details, full price, refund deadline and return procedure before paying. Similar-looking marketplace items are not proof of the branded product’s identity or performance.
The FTC advises consumers to be skeptical of drastic utility-saving promises and to research products and sellers using terms such as “scam” or “complaint.” See its guidance on spotting home-related fraud.

- Record the baseline. Photograph the meter or save the utility account’s kWh usage, billing-period dates and rates before testing. Dollar totals alone can change with rates, fees and billing length.
- Compare equivalent periods. Account for weather, heating and cooling, occupancy, holidays, appliance use and rate changes. A single lower bill does not show that a device caused the drop.
- Measure the right thing. A properly rated plug-in watt meter measures the appliance connected through it. It does not measure whole-home savings or prove that a separate box changed the utility meter’s reading.
- Keep the appliance’s task the same. For an appliance-level test, compare watt-hours over comparable operating conditions, with and without the device. If the appliance does not use fewer watt-hours to do the same job, the claimed saving has not been demonstrated.
- Use a longer view for whole-home use. Compare total household kWh over genuinely comparable billing periods, while recognizing that household changes and weather can confound the result. A basic outlet meter cannot establish whole-home savings.
Do not rely on a glowing LED, a changed voltage reading or a lower dollar bill by itself. The FTC’s home heating and cooling guidance and utility-bill advice point toward practical efficiency steps rather than drastic gadget promises.
If you already bought one
- Stop using it if it becomes hot, smells unusual, makes noise, trips a breaker, causes flickering or shows discoloration. Do not open or modify it.
- Save the order confirmation, advertisement, seller messages, packaging and any stated refund terms. Request a refund in writing and keep a record of the response.
- If the seller does not resolve the issue, contact your card issuer or payment provider promptly to ask about dispute options. Deadlines and protections depend on the payment method.
- Report suspected deceptive marketing to the FTC and the marketplace where you bought it; you can also contact your state consumer-protection office.
- Do not send identity documents or additional sensitive information to an unverified seller. Do not plug an untrusted device into an overloaded outlet, extension cord or power strip just to test it.
The available evidence does not establish that every Pro Power Save-branded or similarly named unit is electrically dangerous. Still, any mains-powered device should have a traceable manufacturer, clear electrical ratings, credible safety certification applicable to your country, and understandable warranty and return terms. Do not assume it is a surge protector or appliance-protection device unless the exact unit has appropriate ratings and certification.
Safer ways to reduce or understand electricity use
- Start with measurement: A plug-in energy meter can show the consumption of an individual appliance; the Kill A Watt product page is one example. It cannot verify whole-home savings.
- Track the whole home: A panel-based monitor such as Sense or Emporia Energy may help identify circuits or loads, but check panel compatibility, installation requirements, electrician needs and current service terms.
- Control appropriate loads: Smart plugs or switched power strips can schedule or shut off suitable standby loads. Do not use them for heaters, motor loads, refrigerators or equipment that must stay on unless the device maker explicitly permits it.
- Target heating and cooling: Air sealing, insulation, thermostat schedules and HVAC maintenance can address real sources of household energy use. The FTC’s heating and cooling guide explains practical steps.
- Check upgrades and rebates: Compare efficiency information when replacing an appliance, and look for rebates or demand-response programs directly through your utility or official program pages. The ENERGY STAR product directory is a starting point for efficiency information.
For a persistent voltage problem, contact your utility or a qualified electrician rather than relying on an anonymous outlet gadget. Commercial facilities with specific power-factor charges should consult a qualified electrical professional about equipment designed for their measured load and billing arrangement.
