Why power adapter price gap so large

There is often a customer response, power adapter rated power of the same, why the market price gap so big? Or even double? 1 watts 1 dollars for only a short while ago, the slogan of service on the power industry, power adapter and look today, many 36W are all below 20 yuan price, so the changed to 1 watts 5 cents? Another angle to see the same industry high-end power adapter products, although prices are way down, but also close to 1 watts 1 yuan level, the power adapter industry really is the price war swallowed? So there is a higher product price difference is how it happened? Let's take a look at the power adapter where the price difference.
Generally speaking, a power adapter is composed of a large number of electronic components, and the electrical potential danger, and a power adapter is not allowed to open the closed shell products. This leads to a number of tile many users only through the power adapter on the nameplate marked and most intuitive price to measure the power supply. Adapter, this seemingly simple "plastic box" inside is far from our imagination as simple. Only materials can affect the quality of a power adapter 70%, and circuit design, production process and other factors also occupy a large proportion. In addition to the rated power, the stability is good or bad influence to the most intuitive the factors of user experience.
A penny, this is a lot of people buy a product concept. The popular point, power adapter internal electronic components of the materials can be divided into three kinds, the lowest level for the old material or false material; the middle level is the highest level of the primary material; is good. The general copycat factory will use the old material false material as brand-name manufacturers will make good use of a little time, but only the brands will use the best quality data, good. So the same level of two 36W power adapter, the average price of 30 yuan products are better than those of only 15 yuan cheap goods.
So, with the concept of "a penny" to describe the power adapter, is the image of a single electronic component. Although the difference is not very obvious, but for the power adapter to use dozens of components, the difference in materials is more obvious. It is not hard to explain why do some of the same level of large power adapter price is higher than the copycat products.
The power adapter, from the initial design to the sales packing, must have a sound R & D, production and testing. In order to ensure the power adapter products consumers eventually get has a stable quality and excellent performance, the whole process of any one of the links is crucial, and these are our consumers easy to ignore in the choice of power adapter details.
Normally, a power adapter after completion of production, in order to test whether meet the design standards of the original, but also after the aging test, electrical performance test and pressure test and so on many aspects. And the test equipment and the environment also need a part of manufacturers to investment. And now these conditions have only some of the regular power plant.
For consumers, the most concern is the final price. But for the domestic power market is very similar, with two power adapter wattage difference may be as high as 50% or more. In our selected power adapter, "not only how much money per watt" standard also to measure. Considering the power adapter brand, materials, workmanship, customer service and other aspects. So that it can make us in a variety of vacuity, market shoddy phenomenon more common on the power adapter to choose from for our own.
