Saver is not cheap

Now that the Power Saver on the market only costs 5-40 yuan, it can save 20%-50% of the power, and it can achieve the power saving effect by connecting to the outlet. Some Power Saver merchants use different products to sell their products. Slogans, even more, even live demonstrations of power saving effects...

Well, these “quiet and inexpensive” Power Savers are expected to have good prospects for development in the world’s call for energy saving and environmental protection. They will be popularized in major electrical malls, supermarkets and other places like the energy-saving lamps, but why? "Boy" stuff only appears in the stall or Taobao?

In the face of so many questions, reporters/experts from various quarters made unannounced visits to understand the real inside story of this “high-tech” product:
First, the electric current becomes smaller to indicate that the power saving is at the hawker's demonstration site: the owner puts out a “saver” and plugs it into a socket of a tow line. The number of ammeters inserted on the same tow line actually fell. The Lord explained that if the current is smaller, it means that the electricity is saved. When it is installed at home, the power meter naturally goes slowly.
Insider 1: Live demonstrations of ammeters are tricks for "promoters," such as using a magnetic device to control the speed of an ammeter to deceive consumers.
Insider 2: When he opened the Saver, he found that there were only two light-emitting diodes and two current-limiting resistors. There was no advanced energy-saving device. The reason for controlling the ammeter may be that the owner controls the ammeter when selling, pretending to cause a change in the current.

Second, the formal manufacturers, there are after-sales website in order to reflect the source of the product is a formal channel, all of these products are printed on the packaging of manufacturers, and after-sales website complete. Prove to buy such products, there is quality assurance.
Insider: The reporter contacted the company on the packaging. After the company’s responsible person received the photo of the Power Saver provided by the reporter, he clearly stated that the product was not produced by the company. Some factory names are even counterfeit.

Here we look at the power-saving principle of the Power Saver: the product is generally divided into lighting and lighting power saver. The use of high-pressure filtering and energy absorption technology automatically absorbs the energy of the reversed potential of the high-voltage power equipment and continuously returns it back to the load, which saves the power drawn by the power equipment from the high-voltage power grid.

Experts suggest that people who want to save electricity may choose to use some smart energy-saving outlets, which are mainly used to reduce standby energy consumption. However, such sockets cannot be “insert all-inclusive”. For example, smart air-conditioning power sockets can only be used for air conditioners and not for other electrical appliances. The price is also more expensive than an ordinary socket, and many of them exceed 100 yuan.

Power Savers do not take precautions against consumers. In particular, some counterfeit “savers” will not only save electricity, but will consume more electricity on the contrary, and they will burn for a long time. This will cause damage to household appliances and electricity meters and remind the public not to believe in scams to avoid losses.
