In my country, the control of power adapters from research and development to manufacturing is very strict. With the continuous innovation and development of smart products, the domestic power adapter industry is also advancing by leaps and bounds. Power adapters of different models and powers have flooded into our lives. However, Due to the differences in the level of manufacturers, business scale, and production processes, there will also be great differences in the quality and price of the power adapters manufactured. So when purchasing, from which aspects can you quickly identify the pros and cons of power adapters? ?
What aspects can we quickly identify? First, check whether the CCC qualification certificate of the power transformer is qualified, second, check the logo of the power adapter, and third check the socket and plug of the power adapter.
In terms of control of power adapters in my country, it belongs to the category of national mandatory verification file directory. Therefore, the circulation of regular power adapters in the Chinese market has been subject to compulsory verification by the state. When you buy a power adapter, we first look at the nameplate logo (CCC certification), and check the product's qualification certificate model on the Internet. problem, then we can pick this power adapter.
When the first step is completed, we will look at the interface and plug of the power adapter. First, determine whether the size of the DC head is consistent with the device you are using. This is the most basic. If the size does not match, it will not work. Then look at Will the DC head be loose? If the interface of the power adapter is unstable, the current of the whole machine will be unstable, which will cause damage to the equipment and cause safety accidents.
The last point is to look at the logo of the power transformer. In fact, this point is similar to the first point, but we determine the main parameters. All the information of a qualified power adapter is indicated on the nameplate, such as voltage, current, energy Consumption level, safety, manufacturer, etc. Of course, if you only use it in China, it must be marked in Chinese, and the information will be very complete.
