Nowadays, with the continuous development and development of smart products, the domestic power adapter industry is also developing rapidly. Different types and powers of switching power adapters have flooded into our lives. However, due to differences in manufacturers’ level, scale and production process, production has followed. The quality and price of the power adapter will also be very different, so how do we identify the advantages and disadvantages of the power adapter?
We can quickly identify from four aspects:
1. Check if the power adapter’s certificate is valid.
For the control aspect of the power adapter, it is a mandatory national certification directory. Therefore, the formal power adapters are compulsory in the domestic market. When we purchase the power adapter, we first look at the nameplate to indicate whether the certification mark is printed. In addition, we can check the certificate model of the product online. Etc. If the product is certified, then we can choose this power adapter.
2, carefully check the power adapter logo
The second step is to look at the interface and plug of the power adapter. First, make sure that the size of the DC head is the same as the one you are using. This is the most basic. If the sizes do not match, then there is no way to use it.
3. Check the interface and plug of the power adapter
Then look at the DC head will be loose, because the interface of the power adapter is unstable, it will cause the current of the whole machine to be unstable, which will cause damage to the equipment and cause a safety accident.
The above is some knowledge about the quality problems of the power adapter.
