Customers often respond that the same rated power adapter, the market price gap why so big? Some even doubled? Once upon a time, a watt and a dollar slogan rang throughout the power industry, and today, many 36W power adapters are below 20 yuan price, then really should change to a watt and a dime? Look at the high-end power adapter products of the same industry from another angle, although the price is also going down, but also close to the level of one watt and one dollar. Is the power adapter industry really engulfed by the price war? Then what is the high price difference between the products? Let's take a look at the price difference of power adapters.
In general, a power adapter consists of a large number of electronic components, and because of potential electrical hazards, a 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 on the adapter's nameplate. Power adapter, this seemingly simple "plastic box" is far less simple inside than we thought. Only material can affect a power adapter 70% of the quality, and circuit design, manufacturing process and other factors also occupy a lot of proportion. In addition to rated power, its stability is the most intuitive factor affecting user experience.
It's the idea that many people buy products. Popularly speaking, the power adapter internal electronic components are roughly divided into three kinds of materials, the lowest level of old materials or fake materials; the middle level of inferior materials; the highest level of good materials. Generally, Shanzhai factories will use used materials, fake materials to charge, miscellaneous manufacturers will use a little better inferior materials, and only a first-line brand will use the best quality of the real materials, good materials. So the same level of two 36W power adapters, the average price of 30 yuan products are better than those bargains of only 15 yuan.
Therefore, it is the most vivid to describe the power adapter with the concept of "one penny for one commodity". Although the difference in the price of a single electronic component is not very obvious, but for power adapters using dozens of components, the difference in the quality of the material used is more obvious. It's not hard to explain why some large power adapters at the same level cost more than counterfeit products.
For power adapters, from the initial design to packaging sales, it is necessary to have a complete set of research and development, production and testing processes. In order to ensure that the power adapter products that consumers ultimately get have stable performance and excellent quality, any part of the process is crucial, and these are the details that our consumers tend to overlook when choosing the power adapter.
Normally, a power adapter after the completion of the production, in order to check whether it meets the original design standards, but also through aging testing, electrical performance testing and high voltage testing and so on. And these test equipment and environment are also part of the investment that manufacturers need to invest heavily. At present, there are only some regular power plants with these conditions.
For consumers, the ultimate concern is the ultimate price. However, for the current domestic power market with very serious homogeneity, the difference between the two power adapters with the wattage may be as high as 50% or more. When we choose power adapters, we should not use only the standard of "how much per watt". We should also consider the brand, materials, workmanship and after-sale of the power adapter. Only in this way can we choose our own power adapters in the market where the phenomena of falsehood and subprime are common.
