What are positive and non-standard power adapters?

April 19, 2023

Many people are not very clear about the positive and non-standard power adapters, YHY told you that is the formal standard power adapter and the irregular production of power adapters. Of course, the difference between them is very large, here is a look at the difference between the two.

1. Raw material cost gap

Positive standard power adapter is completely in accordance with the safety standards to do, capacitance capacity, safety devices, etc., one can not be less, most of the use of industry famous built-in IC, to ensure safety, pay attention to performance, improve product life. Non-standard power adapter can be small in capacitance, safety device province save, IC which is cheap to use which. In this way, it can only guarantee the basic output voltage and current, and even some contain imaginary index components, 0.5A is written as 1A, 1.5A is written as 2A, everywhere.

2. Manufacturing and quality cost gap

According to the ISO quality relationship system go or not, can greatly affect the cost of a product production process and quality detection process, such as power adapter this kind of electronic products, in the production process, the professional degree of personnel, power on each of the original welding, will seriously affect the quality of a product, aging process, whether all aging, aging time is guaranteed, Are closely related to the quality of the product. Quality control process, the proportion of testing, testing skills, testing instruments, are not negligible.

3. After-sales cost

We all know about the iPhone exploding, the Samsung NOTE 7 exploding. Why? Because they are the industry benchmark, their products should be good, this is our subconscious convention, once they have a problem, should not. But we should believe that other small copycat companies, they sell mobile phone charging explosion more. But we don't know. If the Apple and Samsung phone in your hand blows up, you can call Apple and Samsung. If you're unlucky enough to have a phone in your hand that you don't know who made it, and if it explodes, who do you call?
