  Customers often respond that with the same rated power power adapter, why is there such a big gap in the price on the market? Some even doubled? Once upon a time, the slogan of 1 watt and 1 yuan has been heard throughout the power supply industry, but today, many 36W power adapters are priced below 20 yuan, so should it really be changed to 1 watt and 5 cents? Looking at the high-end power adapter products in the same industry from another angle, although the price is also falling all the way, it is also close to the level of 1 watt and 1 yuan. Is the power adapter industry really swallowed by the price war? Then the product has a higher price difference. It is how it happened? Let us take a look at the difference in the price of power adapters.

Why is the price gap of power adapters so big?(图1)

  Generally speaking, 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 does not allow the shell to be opened. This has led many users to measure by only the wattage and the most intuitive price indicated on the nameplate of the power adapter. The power adapter, the inside of this seemingly simple "plastic box" is far less simple than we thought. Only the materials used can affect 70% of the quality of a power adapter, and factors such as circuit design and manufacturing technology also take up a lot of proportion. In addition to the rated power, its stability is the most intuitive factor that affects the user experience.

  You get what you pay for, this is the idea that many people buy products. In layman's terms, the materials used in the internal electronic components of the power adapter are roughly divided into three types, the lowest level is old materials or fake materials; the middle level is inferior materials; the highest level is good materials. In general, knock-off factories will use old and fake materials to replenish their numbers. Non-brand manufacturers will use better inferior materials, and only first-line brands will use the best quality genuine materials and good materials. Therefore, the average price of the two 36W power adapters of the same level is 30 yuan, which is better than the cheap ones with only 15 yuan.

  Therefore, it is the most vivid to describe the power adapter with the concept of "you get what you pay for". Although the price difference of a single electronic component is not very obvious, for a power adapter that uses dozens of components, the difference in the quality of materials is more obvious. It is not difficult to explain why the prices of power adapters from some large manufacturers of the same level are higher than those of counterfeit products.

  For the power adapter, from the initial design to the packaging and sales, a complete set of R&D, production and testing procedures are necessary. In order to ensure that the power adapter products that consumers finally get have stable performance and excellent quality, any link in the entire process is very important, and these are the details that our consumers are more likely to ignore when choosing a power adapter.

  Normally, after a power adapter is manufactured, in order to check whether it meets the original design standards, it will go through multiple links such as aging test, electrical performance test and high voltage test. These test equipment and environments are also part of the need for manufacturers to invest heavily. At present, only some formal power plants have these conditions.
