There will often be a customer response that the rated power of the same power adapter, the price on the market why there is such a big gap? Some even double, right? Once upon a time, the slogan of 1 watt 1 yuan echoed throughout the power industry, and look at today, many 36W power adapters are under 20 yuan price, so really should be changed to 1 watt 50 cents? Take a look at the same high-end power adapter products from another point of view, although the price is also falling, but also close to the level of 1 watt 1 yuan, power adapter industry is really swallowed by the price war? So what about the high price difference? Let's take a look at the differences in power adapter prices.

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 housing to be opened. This has led many users to simply look at the wattage on the nameplate of the power adapter and the most intuitive price. Power adapter, the inside of this seemingly simple "plastic box" is not as simple as we think. Only materials can affect the quality of 70% of a power adapter, and circuit design, production process and other factors also occupy a lot of proportion. In addition to rated power, its stability is the most intuitive factor affecting the user experience.

You get what you pay for. That's the philosophy many people buy products with. Generally speaking, the materials used in the internal electronic components of the power adapter are roughly divided into three kinds, the lowest level for the old materials or fake materials; Intermediate level is secondary material; The highest grade is good. Generally, shanzhai factories will use old materials and fake materials to fill the number, and miscellaneous manufacturers will use better secondary materials, while only first-line brands will use the best quality real materials and good materials. So the two 36W power adapters in the same category, with an average price of 30 yuan, are better than those cheap ones that cost only 15 yuan.

Therefore, the concept of "you get what you pay for" to describe the power adapter, is the most graphic. Although the difference in individual electronic components is not very obvious, but for the use of dozens of components of the power adapter, the difference in material quality is more obvious. It is not hard to explain why some of the big manufacturers of similar power adapters are more expensive than the knockoffs.

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 procedures. Every part of the process is crucial to ensure that the power adapter that consumers end up with has stable performance and excellent quality, and these are the details that we consumers tend to overlook when choosing a power adapter.

Normally, after the production of a power adapter, in order to check whether it meets the original design standards, it will also go through aging test, electrical performance test and high voltage test and so on. And these testing equipment and environment is also a part of the need for manufacturers to invest heavily. At present, only some formal power plants have these conditions.

For consumers, what matters most is the final price. However, for the current very homogeneous domestic power supply market, the difference between the two power adapters of the same wattage may be as high as 50% or more. When we choose a power adapter, we can't just use the "less money per watt" standard to measure. But also comprehensive consideration of the power adapter brand, materials, workmanship, after-sales and other aspects. In this way, we can choose our own power adapter in the market where the phenomenon of false label and shoddy goods is more common.
