Where is the difference between the two?
1: Raw material cost gap, the standard power adapter is completely in accordance with the safety standards, capacitor capacity, safety devices, etc., one can not be less, mostly use the industry-renowned built-in IC to ensure safety, focus on performance, 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 with virtual targets, 0.5A is written as 1A, and 1.5A is written as 2A, which is everywhere.
2: Manufacturing and quality cost gaps, according to the ISO quality relationship system, can greatly affect the cost of a product production process and quality inspection process, such as power adapters, electronic products, in the production process, personnel professional The degree, the welding of each original on the power supply 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-sales costs, we all know that Apple's mobile phone exploded, 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 are small cottages, the phones they sell will charge more. But we don't know. If the Apple Samsung mobile phone in your hand is bursting, 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 mentioned is only 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.
