standard and unstandard power adapter

1: Raw material cost differency, standard power adapter is completely in accordance with safety inspection standards, capacitance capacity, 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. Non-standard power adapters can be small or small in terms of capacitor capacity, devices can save time, and which one 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.

2: The cost differency between manufacturing and quality, whether it conforms to the ISO quality system, 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 personnel, 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.
