How does the power adapter factory teach you to distinguish the advantages and disadvantages of switching power adapters?
In China, the control from R & D to production of switching power adapters is very strict. However, with the continuous updating and development of intelligent products, the domestic power adapter industry is also developing rapidly. A large number of switching power adapters of different models and powers have poured into our lives. However, due to the differences in manufacturer level, scale and production process, the quality of power adapters produced subsequently There will also be great differences in price, so how can we identify the advantages and disadvantages of switching power adapter?
We can quickly identify from four aspects:
1. Check the safety certificate of the power adapter
The control of power adapter in China belongs to the national compulsory certification catalogue. Therefore, the regular power adapter has passed the national compulsory certification in the domestic market. When we buy the power adapter, we first look at whether the nameplate is printed with the mark of conformity. In addition, we can query the certificate model of the product online. If the product has passed the safety certification, we can choose this power adapter
2. Carefully check the label of the power adapter
The second step is to look at the interface and plug of the power adapter. First, determine whether the size of the DC head is consistent with the equipment you are using. This is the most basic. If the size does not match, it will not work.
3. Check the interface and plug of the power adapter
Then check whether the DC head is loose. If the interface of the power adapter is unstable, the current of the whole machine will be unstable, which will damage the equipment and cause safety accidents.
