Why the power adapter price gap is large, Scott as a professional manufacturer of electronic power adapter today to give you a analysis of this problem:
In general, a power adapter is composed of a large number of electronic components, and due to potential electrical hazards, the power adapter is a closed product that is not allowed to open the enclosure. This leads to a lot of users to measure the wattage and the most intuitive price on the nameplate of the power adapter. The power adapter, the seemingly simple "plastic box", is not as simple as we think. Only material aspects can affect the quality of a power adapter 70%, and circuit design, production process and other factors also occupy a lot of proportion. In addition to the rated power, its stability is the most intuitive factor affecting the user experience.
It's the idea that many people buy products. Popular point, power adapter internal electronic components of the materials can be divided into three kinds, the lowest level for the old material or false material; the middle level is the highest level of the primary material is good. The old factory will generally copycat material, false material as brand-name manufacturers will make good use of a little time, but only the brands will use the best quality materials, really good. So the same level of two 36W power adapter, the average price of 30 yuan product is better than those only 15 yuan of cheap goods.
So, with the concept of "one cent a penny goods" to describe the power adapter, is the most image of the. Although the price difference of a single electronic components is not very obvious, but for the use of dozens of components of the power adapter, the difference between the quality of the material on the more obvious. It is not difficult to explain why some of the same class of power adapter prices are higher than Shanzhai products.
For the power adapter, from the initial design to the packing sale, it is necessary to have a complete set of R & D, production and testing process. In order to ensure the power adapter products consumers eventually get has a stable quality and excellent performance, the whole process of any one of the links is crucial, which is relatively easy to ignore our consumers in the choice of power adapter details.
Normally, a power adapter after the completion of the test, in order to test compliance with the original design standards, but also through aging test, electrical performance testing and high voltage testing and so on. And these test equipment and the environment is also part of the strong investment needs of manufacturers. At present, there are only some regular power plants with these conditions.
For consumers, the ultimate concern is the final price. However, for the current domestic power market with very serious homogenization, the price difference of two power adapters with watt number may be as high as 50% or more. When we select the power adapter, we can't measure it only with the standard of "how much per watt.". Also consider the power adapter brand, materials, workmanship, after-sales and many other aspects. Only in this way can we let the market in a variety of vacuity, shoddy phenomenon more common on the power adapter to choose from for our own.
