  1: The cost of raw materials is different. Positive standard power adapters are made in accordance with safety standards. Capacitor capacity, safety devices, etc., one cannot be missed. Most of them use well-known built-in ICs in the industry to ensure safety, focus on performance, and improve product life. Non-standard power adapters can be smaller and smaller in capacitance capacity, and safety devices can be omitted. Which IC is cheaper to use. In this way, it can only guarantee the basic output voltage and current, and even some components contain virtual standard, 0.5A is written as 1A, 1.5A is written as 2A, and there are many.

  2: The gap between manufacturing and quality costs, according to the ISO quality relationship system, can greatly affect the cost of a product's production process and quality inspection process. For electronic products such as power adapters, in the production process, the professionalism of personnel The degree of welding of each original on the power supply will seriously affect the quality of a product. During the aging process, whether all the components are aging and whether the aging time is guaranteed are closely related to the quality of the product. The quality control process, the proportion of testing, the skills of testing, and the testing equipment cannot be ignored.

  3: After-sales cost, we all know that Apple phones 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 believe that other small companies that make copycat phones sell more mobile phone charging explosions. But we don't know. If the Apple and Samsung mobile phone in your hand explodes, you can find Apple and Samsung. If unfortunately you don't know who made the phone in your hand, even if it explodes, who can you turn to.

  Of course, the above is just a little bit. We have to believe that you get what you pay for. There is a reason why BMW and Benz are expensive. Whether the power adapter has passed the safety certification is absolutely a guarantee of its quality.
