    Why is the price difference between power adapters so large?
    time:2019-07-05 10:02        Click volume:【236 】Times

    There are often customers who say that the power adapter with the same rated power, why is the price on the market so wide? Some even doubled? Once upon a time, the slogan of 1 watt and 1 dollar rang throughout the power industry, and today, many 36W power adapters are at the price below 20 yuan, so really should be changed to 1 watt 5 cents? Looking at the high-end power adapter products in the same industry, although the price is also lower, but it is close to the level of 1 watt and 1 dollar, 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 look at the difference in the price of the power adapter.

          Typically, a power adapter consists of a large number of electronic components, and because of the potential electrical hazard, the power adapter is a closed product that does not allow the enclosure to be opened. This has led many users to measure only the wattage and the most intuitive price indicated on the power adapter nameplate. The power adapter, the seemingly simple "plastic box" inside is far less simple than we think. Only the material aspect can affect the quality of a power adapter 70%, and the circuit design, production process and other factors also occupy a large proportion. In addition to the rated power, its stability is the most intuitive factor affecting the user experience.

          One penny is worth the price. This is the idea that many people buy products. Generally speaking, the materials used in the internal components of the power adapter are roughly divided into three types, the lowest level is the old material or the fake material; the middle level is the secondary material; the highest level is the good material. Generally, the cottage factory will use old materials and fake materials to fill the number. The brand-name manufacturers will use a little bit of secondary materials, and only the first-line brands will use the best quality materials and good materials. Therefore, the two 36W power adapters of the same level, the average price of 30 yuan is better than those of only 15 yuan.

          Therefore, the concept of "a penny and a share of goods" to describe the power adapter is the most vivid. Although the difference between a single electronic component is not very obvious, but for a power adapter using dozens of components, the difference in the quality of the material is more obvious. This is not difficult to explain why some of the same level of power supply adapters are higher than the cottage products.

          For the power adapter, from the initial design to the boxing sales, there must be a complete set of R&D, production and testing procedures. In order to ensure that the power adapter products that consumers ultimately get have stable performance and excellent quality, any part of the whole process is crucial, and these are the details that our consumers are more likely to ignore when choosing a power adapter.

          Normally, after the completion of a power adapter, in order to verify compliance with the original design standards, it will also undergo 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. Currently, there are only some regular power plants with these conditions.

          For consumers, the most concerned is the final price. However, for the current domestic power supply market with very homogenization, the difference between the two power adapters with the wattage may be as high as 50% or more. When we choose a power adapter, we can't just measure it by the "how much per watt" standard. It is also necessary to comprehensively consider the brand, materials, workmanship, and after-sales of the power adapter. In this way, we can select the power adapter that suits us in the market where the virtual standard and the shoddy are more common.
