In fact, the so-called positive and non-standard power adapters are worthy of the formal standard power adapter and the value of the power adapter that is not produced. Of course, their gap is very huge, today we will take a look at the gap between the standard and non-standard power adapters.
1. Raw material cost gap
The standard power adapter is completely in accordance with the safety standards. Capacitance capacity, safety devices, etc., one can not be less, most of them use the well-known built-in IC in the industry to ensure safety, focus on performance, and improve product life. The non-standard power adapter can be smaller or smaller in terms of capacitor capacity, and the safety device can be omitted in the province. Which IC is cheaper to use? In this way, it can only guarantee the basic output voltage and current, and even some components containing the virtual standard, 0.5A is written as 1A, and 1.5A is written as 2A, which is everywhere.
2, manufacturing and quality cost gap
According to the ISO quality relationship system, it can greatly affect the cost of a product production process and quality inspection process, such as the power adapter, the electronic product, the production process, the professional level of the personnel, and the original of each of the power supplies. Welding will seriously affect the quality of a product. Whether it is all aging during the aging process, whether the aging time is guaranteed or not, is closely related to the quality of the product. The quality monitoring process, the proportion of detection, the testing techniques, and the testing instruments are all not to be ignored.
3, after-sale costs
We all know that the Apple phone exploded and the Samsung NOTE 7 exploded. Why? Because they are the benchmark of the industry, the products they make should be good. This is what we have in the subconscious. Once they have problems, they should not. But we should be more convinced that other small companies that do cottage machines, they sell more mobile phone charging explosions. But we don't know. If the Apple Samsung mobile phone in your hand bursts, you can find Apple and Samsung. If you are unfortunately the mobile phone in your hand, you don't know which one is produced. If it is explosive, who can you find?
Of course, the above is just a little bit. Everyone must believe that one point is worth the price. BMW Mercedes has its own reason. Whether the power adapter passes the safety certification is absolutely a guarantee that its quality will pass.
