What are positive and non-standard power adapters
1: 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 the use of industry-renowned built-in IC, to ensure safety, pay attention to performance, improve product life. Non-standard power adapters can be smaller and smaller in capacitance capacity. Safety devices will be omitted in this 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 labels, 0.5A written in 1A, 1.5A written in 2A, everywhere.
2: The gap between manufacturing and quality cost, according to the ISO quality relationship system, can largely affect the cost of a product production process and quality testing process, such as power adapter, in the production process, the professional level of personnel, welding of each original part of the power supply, will seriously affect the quality of a product, whether all the products are old in the aging process. Whether aging time is guaranteed or not is closely related to the quality of products. The process of quality monitoring, the proportion of testing, the skills of testing and the instruments of testing should not be neglected.
3: After-sales costs, we all know that the Apple phone exploded, Samsung NOTE 7 exploded. Why? Because they are the benchmark of the industry, the products they make should be good. This is a convention in our subconscious. Once they have problems, they should not. But we should also believe that other small companies that make Shanzhai phones sell more mobile phones to charge and explode. But we don't know. If the Apple Samsung phone in your hand explodes, you can find Apple and Samsung. Unfortunately, if the cell phone in your hand is not known which one is produced, even if it explodes, who can you find?
