These findings are the latest in a long series of investigations that show the checks and measures in place on online marketplaces to prevent the sale of unsafe, illegal products are still woefully inadequate. Safety checks from online marketplaces offering these products also appear to have missed numerous adverts and videos for these scam ‘energy-saving’ boxes on social media platforms. Plus six were fitted with unmarked, non-standard capacitors (which store electric charge), and all but one had poor quality soldering, indicating that they weren’t manufactured to UK standards.
‘It’s incredibly concerning to see that these scam eco-plugs are still widely available on many online marketplaces, despite the fact that they are illegal and potentially a danger to their users. Based on this evidence, it could be just as likely to put customers at risk of buying unsafe products as the other marketplaces Which?

Potential fire and electric shock risk
Stop Watt is exclusively available online, sold through questionable third-party sites. The StopWatt website showcases entirely fabricated testimonials and narratives, using generic images of fake customers. No plug-and-play gadget can significantly cut your home’s energy consumption. There is no proof that Stop Watt conserves electricity, let alone deliver the claimed 90% savings on utility bills. Its components are basic and fail to produce any measurable effect on household energy usage.
A small capacitor might marginally adjust power factor in specific cases, but this rarely translates to reduced residential electricity (kWh) consumption. The LED indicator on plug-in suggests functionality, but illumination alone cannot prove meaningful energy savings. Such devices face widespread criticism because their internal components rarely justify exaggerated claims about slashing residential electricity costs. A frequent complaint in this category is hidden subscription fees buried in fine print, depending on the seller’s sales strategy. The countdown timer often misleads buyers about actual stock availability.
Power Pro Genius is a plug-in designed to stabilize home electrical currents and filter out dirty electricity. At its worst, it poses a serious electrical hazard and fire risk. The StopWatt Pro Power Saver is sold online solely through unverified third-party platforms. The official StopWatt Pro Power Saver site features entirely manufactured reviews and stock photos of fake users. No evidence supports claims that StopWatt Pro Power Saver saves electricity, let alone claims of 90% bill reductions.

Dirty electricity—ranging from flickering lights to overheating devices and increased power drain—silently damages appliances and inflates bills. Many homeowners remain unaware of poor power quality issues, which often go unnoticed until costly damage occurs. This issue not only wastes electricity but can also degrade sensitive electronics over time. Another frequently overlooked but damaging problem is dirty electricity, which introduces electrical noise and voltage spikes into home wiring.
The government’s Product Regulation and Metrology Bill could provide a historic opportunity to safeguard online shoppers and enforce stricter accountability on digital marketplaces for unsafe products. In 2022, four similar devices sold on AliExpress, eBay, and Wish were recalled by authorities due to “serious fire and electric shock risks.” Scam products from online marketplaces have repeatedly failed lab safety tests, faced multiple government recalls, and misled buyers with exaggerated shipping claims. If card fraud is suspected, financial institutions typically advise card replacement. Poorly made plug-in electrical devices pose inherent safety risks, particularly when manufacturing quality is compromised.
On the flip side, StopWatt has drawn criticism from both users and watchdog organizations for failing to meet expectations. A number of users across online forums and third-party retail platforms have shared stories of reduced power bills, improved appliance performance, and peace of mind from using StopWatt. Some users report modest improvements in their electricity bills and claim noticeable reductions in device overheating and voltage irregularities. In sum, StopWatt uses fundamental electrical concepts like surge protection, voltage regulation, and basic power factor correction. That said, the term dirty electricity filter continues to trend in consumer circles, especially among those looking for eco-conscious smart home solutions. The concept of dirty electricity—a form of electrical pollution caused by spikes in electromagnetic interference (EMI)—is controversial.
