Can the use of the "divine tool" slow down the "electricity meter"? Authoritative Appraisal: Fake Merchant | Energy Saver | Authoritative

Some merchants claim that "energy-saving appliances" can save a lot of electricity by plugging in the power supply. Authoritative institutions have determined that they have no energy-saving effect

Power supply department to remind: all interference meter behavior is illegal

With the arrival of the hot summer, the neighborhood's electricity bills have generally risen from the previous few months. Recently, when a reporter was shopping on an e-commerce platform, he found that the platform had recommend the so-called "power saving artifact" to the reporter: the merchants selling this "power saver" claimed that as long as it was plugged into the socket at home, it could play an amazing role in saving electricity-"after plugging in, the electricity meter would not go", "only 10 kilowatt-hours a year", and even some merchants said they could "turn the electricity meter backwards".

Then, do these "artifacts" really have the role of business propaganda? Where is it produced? Is it suspected of breaking the law? How should consumers protect their rights? The reporter conducted an investigation.

Merchant Video:

"Artifact" after the use of "meter" slow

After recommend the so-called "power saving artifact" to the reporter on an e-commerce platform, the reporter searched for the word "power saver" on the platform. then the reporter found hundreds of merchants selling goods such as "energy saving king", "super power saving king" and "high-power power saving black technology". The sales prices of these "power saver" ranged from tens of yuan to hundreds of yuan, but the method of use is basically the same-plug the saver into the socket in the home to slow the meter down. However, among the sales volume of these merchants shown on the platform, the most has reached the monthly sales 2000.

As a result, the reporter and the business customer service consulting the role of the product. A customer service enthusiastically showed reporters a video of the product. In the video, a man spoke in less standard Mandarin and declared that "the effect of power saver can reach 100, and the refund is invalid". In the video, the reporter saw that the man also did an experiment: he turned on the hair dryer, and the "meter" on the side began to rotate, and when the man plugged the "saver" into the power supply, the "meter" immediately "brake", and when the man unplugged the "saver", the "meter" began to rotate rapidly. The man said that the "artifact" can be plugged into any socket in the home, and the old and new meters are applicable, "saving half of the electricity bill in one month easily".

The customer service further publicized to the reporter: "The product has been installed and debugged before leaving the factory. It is not necessary to install and receive it and plug it directly into any socket at home. We are intelligent and fully automatic to stabilize the voltage within 100 square meters. It is very convenient. We are not aiming at saving electricity for an electrical appliance, but optimizing your overall electricity consumption, as long as it is a connected circuit under an electric meter." When the reporter asked about its working principle, the customer service replied: "The power saving principle is to optimize the voltage and balance the current loss in the current recovery circuit, form a complete reverse current inside the recovered current, press it back through the live wire for reuse, and automatically adjust the current size according to the energy consumption of the electrical appliance to increase the power to achieve the power saving effect."

The price of this "power saver" consulted by the reporter is 30.8 yuan. Customer service said that this style can achieve 15% power saving effect. If you want to achieve the effect of "saving half of electricity" as in the video, you need to buy the new model launched by the company this year, which costs 58.8 yuan. When the reporter asked "is it safe to use the product" and "what if it is found", the customer service replied decisively: "it's legal, dear."

Testing institutions:

After testing, "artifact" has no power saving effect

In order to further investigate the "power saver", the reporter bought one from the platform and sent it to the Guangzhou Power Supply Bureau for verification. The Guangzhou Power Supply Bureau attached great importance to this and immediately entrusted it to a third party-Guangzhou Institute of Metrology and Testing Technology for testing.

The reporter saw that the "power saver" was written with the words "intelligent power saving system", claiming to save 15% ~ 45% of electricity bills, and said that the product "saves electricity, money, green, environmental protection and health", and even has the words "original genuine goods, mobile phone scanning two-dimensional code to check authenticity. However, when the reporter scanned the code with his mobile phone, a web page that had nothing to do with the product came out.

On June 7, the Guangzhou Institute of Metrology and Testing Technology issued a test report, confirming that this so-called "power saver" did not have any power-saving effect. It is reported that the detector heats 1.5L of water with the same temperature to a boiling state, and circulates 10 times when there is no "power saver" involved in the circuit, with a cumulative power consumption of 1.4kwh; However, after the "power saver" is connected for 10 cycles, the cumulative power consumption is 1.41kwh. It can be judged from the detection result that the "power saver" has no power saving effect.

guangzhou city power supply bureau:

Abnormal interference with electric energy meter is illegal

According to the test report, Guangzhou Power Supply Bureau also made the following reply to the reporter:

Recently, a large number of artifacts called "power saver" have appeared in the market, claiming to save 40% ~ 50% of electricity. The publicity is very exaggerated, and it is accompanied by demonstration videos, and its sales volume is also very high. In order to find out and verify its authenticity, Guangzhou Institute of Metrology and Testing Technology conducted experimental testing on the "power saver" on the market. According to the experimental analysis, it is concluded that the "power saver" sold on the market has no effect on the power consumption before and after use, nor can it save 40%-50% of the power as stated in the advertisement, which is suspected of false propaganda. All the equipment and methods that use abnormal legal means to interfere with the normal operation of the electric energy meter are illegal acts of stealing electricity, so consumers should be cautious in consumption.

Journalist investigation:

Site "No Check Here" Official Website "Maintenance"

What is the manufacturer in the production and sales of "power saver"? A few days after the purchase of the product, the reporter once again logged on the e-commerce platform found that the online store has been closed.

In the instruction manual of the "power saver", the reporter saw that its manufacturer was "33X Energy Saving Technology Co., Ltd." and the company telephone number, company address and company website were also written in the instruction manual.

When the reporter inquired about the company in the "Tianyan Check" software and the "National Enterprise Credit Information Publicity System", he did not find any relevant information; through the search of multiple maps, the reporter found that the company's address on the manual could not be searched. When entering the manufacturer's website, the reporter also found that the words "website is being maintained" appeared on the website.

Finally, the reporter dialed the mobile phone number left on the manual, but a man answered. The other party said that he was the owner of the energy-saving technology co., ltd. and the company produced "power saver. But when the reporter told him that the product he bought had no effect, the other party replied: "if you think it has no effect, in this case, you can consult customer service for a refund, we do not force it." When the reporter said that the online store had been closed and no refund could be found, the man became impatient and quickly hung up the phone.
