Can the power saver really save electricity?

There is no scientific experiment to prove that the economizer can save electricity, and many e-commerce companies promote the economizer, which leads to good sales, but there is no scientific statement to prove that the economizer can achieve the effect of online publicity.

This kind of power saver has a simple structure and looks like a box. There is a plug on it. When in use, just plug in the power supply to save electricity. Merchants claim that the purpose of saving electricity is not to steal electricity, but to achieve the purpose of saving electricity through high technology, which can save more than 20% of electricity in China, and the products are very popular.

The test results show that the power saver does not affect the power consumption of electrical appliances. When the electrical appliance is unplugged, the instantaneous power consumed by the electrical appliance will be reduced. In other words, when using so-called energy-saving appliances, the energy consumption of families will increase. Protect household appliances, reduce line loss, overload and overvoltage protection, compensate reactive power on the spot, and improve power factor and efficiency.

In fact, many "power savers" only have one capacitor connected to a circuit board, and a small capacitor costs a few dollars, without subversion.

Capacitors, as the name implies, are "containers for charging", which can store positive and negative charges. In daily life, there are capacitors as big as wires and as small as electronic motherboards. Capacitors have the functions of storing electric energy, alternating current, power filtering, signal filtering, signal coupling, resonance, filtering and reactive power compensation. And it is impossible to save electricity by 20%-50%!
