  1. How to determine the reliability of the power adapter?

  The reliability of the power adapter can be divided into inherent reliability, use reliability, and environmental adaptability.

  Intrinsic reliability refers to the inherent reliability of the product during design and manufacturing. For power adapters and other electronic equipment, inherent reliability includes the complexity of the power adapter, the selection and application of circuits and components, the working parameters and reliability of the components, mechanical structure and manufacturing process, etc.; for components It includes the quality of raw materials, manufacturing processes, working parameters, etc.

  Using reliability refers to the influence of operation and maintenance personnel on product reliability, which mainly includes the correctness of operation methods, maintenance procedures and methods, and the influence of other human factors. The reliability of use depends on the person using the equipment. Skilled and correct operation, timely maintenance and maintenance can significantly improve the reliability of use.

  Environmental adaptability refers to the impact of the product's environment (including work, storage and transportation environment, etc.) on reliability; it mainly includes climatic environmental conditions, mechanical environmental conditions, storage conditions, and transportation conditions. Taking effective protective measures for electronic equipment can improve the environmental adaptability of the equipment.

  The reliability of the power adapter mainly refers to the effective working life of the power adapter. The effective working life refers to the time during which the power adapter can effectively complete the power supply function and maintain the designed electrical characteristic parameters. The reliability of the power adapter has a great relationship with the failure rate of the components and the reliability structure of the whole machine.

  2. How to interpret the energy efficiency rating of the power adapter?

  On the nameplate of the power adapter product, there is generally a parameter called Efficiency Level, which is usually represented by Roman numerals. It is related to the efficiency of the power adapter. The higher the energy efficiency level, the higher the efficiency of the power supply.

  V represents the five-level energy efficiency, and Ⅵ represents the sixth-level energy efficiency. The sixth level of energy efficiency is also the highest energy efficiency standard at present, which means that the power adapter is more efficient and more energy-saving.

  In fact, the early power adapters did not have energy efficiency rating restrictions. Due to the increasing number of electronic products, in order to supply power to the equipment, too much power was consumed on the power adapter, which caused a lot of pressure on the environment, so the energy efficiency rating plan was promulgated. Manufacturers in many countries have also adopted it.

  Energy efficiency rating is now an important parameter of the power adapter, which will have an impact on the selection and export of the power adapter. For example, the United States has now enforced the six-level energy efficiency standard. Then there are only five-level energy efficiency power adapters, so they cannot be sold in the US market.

  The reliability of the power adapter is something that everyone needs to consider carefully before buying. Improving the energy efficiency of the power supply is the general trend, but not all manufacturers have that kind of technical strength. In the process, many power supply manufacturers with weak strength and poor technology will Was slowly eliminated.
