Today, many brands of system power savers have emerged in the market, including those from the United States, Germany, the United Kingdom, France, and other countries. In fact, they are all surge protectors. The author's company is a professional power protection company, and electronic products have become an indispensable part of people's lives. What JOSLYN in the United States advocates is system surge protection, from the main distribution cabinet to sub-distribution cabinets to equipment, with three levels of detailed division. Its main function is 20% lightning protection and 80% absorption of internal startup surges of equipment. However, these electronic products that rely on battery power may have some headaches. The price of large current generators in Shanghai will not affect equipment downtime, maintenance costs, and will not delay the service life of equipment.

System power savers on the market, as long as we establish a service concept, scientific concept, and legal concept, are actually power protection. At that time, the author was skeptical about the energy-saving results touted on the market. "Practice is the sole criterion for testing truth." Multiple lithium battery explosion accidents have made people realize that small lithium batteries can also cause significant harm. For a textile factory, three-level control was implemented. After one month of comparison, the energy-saving result was only 1.6%. Although many electronic products now have overload protection devices, there is also the quality issue of surge protectors (involving technical issues that cannot be explained in a few words, making the YBB standard more scientific and reasonable to guide production, use, inspection, and other related units). Among them, the process requirements for varistors are very high, and the problem of thermal instability is an important factor affecting the safety of the power grid.

Assuming the quality of the surge protector is quite good, therefore never let lithium batteries be in extreme temperature environments for a long time, as there is a fire hazard. However, the author believes that promoting surge protectors as system power savers is extremely irresponsible. By relying on the scientific research projects undertaken by the conference secretariat to drive the improvement of standards, where is the integrity?
