Customers or consumers often respond that why is the price difference so large for power adapters with the same rated power? Some even doubled or doubled? Once upon a time, the slogan of "one watt, one yuan" was heard all over the power supply industry. But today, many 36W power adapters are priced below 20 yuan, so should they really be changed to "one watt, five cents"? Looking at high-end power adapter products in the same industry from another perspective, although the price has been falling all the way, it is close to the level of one watt and one yuan. Is the power adapter industry really swallowed up by the price war? What about the high price difference of products? Let's take a look at the price difference of power adapter.
Generally speaking, a power adapter is composed of a large number of electronic components. Due to the potential electrical hazards, the power adapter is a closed product that is not allowed to open the shell. This leads many users to measure the power adapter only by the wattage indicated on the nameplate and the most intuitive price. The power adapter, which looks like a simple "plastic box", is not as simple as we imagined. Materials alone can affect 70% of the quality of a power adapter, while circuit design, manufacturing process and other factors also account for a lot of proportion. In addition to the rated power, its stability is the most intuitive factor affecting the user experience, and the safety problem cannot be ignored.
It is the philosophy of many people to buy products according to the price. Generally speaking, there are three kinds of materials for electronic components in the power adapter, the lowest level is used materials or fake materials; The intermediate level is secondary material; The highest level is good material. Generally, copycat manufacturers will use old materials and fake materials to make up the number. Miscellaneous manufacturers will use better inferior materials, while only first-line brands will use the best quality real materials and good materials. Therefore, two 36W power adapters of the same level, with an average price of 30 yuan, are better than those bargains with only 15 yuan.
Therefore, it is the most vivid to use the concept of "one price, one goods" to describe the power adapter. Although the difference in the price of a single electronic component is not very obvious, for power adapters that use dozens of components, the difference in the quality of materials is obvious. It is not difficult to explain why the price of power adapters from some large manufacturers of the same level is higher than that of counterfeit products.
For the power adapter, it is necessary to have a complete set of R&D, production and testing processes from the initial design to packaging sales. In order to ensure that the power adapter products that consumers finally get have stable performance and excellent quality, any link in the whole process is crucial, and these are details that our consumers are easy to ignore when choosing power adapters.
Normally, a power adapter will go through aging test, electrical performance test, high voltage test and low voltage test to check whether it meets the original design standard after being manufactured. These test equipment and security environment are also part of the need for manufacturers to invest heavily. At present, only some formal and powerful power adapter manufacturers can meet the high standard conditions of human, machine, environment and safety.
For consumers, the most important thing is the final price. However, for the current domestic power supply market, where homogeneity is very serious, the price difference between two power adapters of the same wattage may be as high as 50% or more. When we choose the power adapter, we can not only use the standard of "how much per watt" to measure. The brand, material, workmanship, after-sales, safety and other aspects of the power adapter should also be comprehensively considered. In this way, we can select our own power adapter in the market where various virtual labels, shoddy products and other phenomena are common.
This is the price difference between the jerry built power adapter and the real one.
