Energy saving appliances are generally divided into lighting fixtures and power saving appliances. The design principles of energy saving appliances are generally based on principles such as reactive power compensation, voltage regulation, peak current leveling, buffer absorption, etc. According to different usage scenarios, different specifications and models of energy-saving products are designed and produced. The main electronic device of a 'saver' is a capacitor. If a resistive or capacitive circuit is connected, it can also cause overcompensation, and the current will increase instead. System energy-saving devices, motor energy-saving devices, lighting energy-saving devices, air conditioning energy-saving devices, boiler energy-saving devices, pumping unit energy-saving devices, etc. At present, there are various types of energy-saving appliances, with mixed advantages and disadvantages. Therefore, when purchasing energy-saving appliances, one should be careful not to use them in vain. It is recommended to maintain a clear mind when choosing to avoid being deceived. Previously recognized energy-saving appliances were mostly used in the industrial sector, and a set of industrial energy-saving appliances is expensive, with higher prices even reaching 10000 yuan. The household energy-saving appliances sold on e-commerce platforms, in addition to the "empty shell" energy-saving appliances encountered by netizens, also have capacitors placed inside the shell
