What is the difference between a power adapter and a conversion socket? How to authenticate?
1. What is the difference between a power adapter and a conversion socket?
1. The conversion socket is to prevent the power jacks of the two places from being different, which may cause your electronic equipment to not be connected to the more productive connection accessories.
It has nothing to do with voltage and cannot be transformed. Transformers are needed to transform electricity. At the same time, due to the different types of plugs and sockets in different places, we often need to carry various sockets to fly around, which led to the birth of the Global Pass conversion socket.
2. The power adapter is a small connector with its own transformer function, which can be different according to the different jacks. The most common is the charging plug of the notebook, also called the power adapter.
Even if you have a power adapter, if you travel abroad on a business trip, you need to use a conversion socket. Of course, it is recommended to use a GSM conversion socket. Poor quality conversion sockets and power adapters are an important cause of electrical fires. The quality problems of small plugs, sockets and converters will pose a serious hazard to the personal and property safety of consumers. At the same time, it is also hoped that consumers should focus on the safety of the products when purchasing plugs, sockets, converters, and switches. They also need to pay attention to the use of these products in their daily lives.
2. Certification of power adapter
Doing a certification for a power adapter requires dozens of tests according to international standards: for example, IEC60950 is an IT-type test standard. For power supplies, there are some tests as follows during certification:
1. EMC interference and anti-interference test, lightning test, static test
2. Safety test: plug test, drop test, high pressure test, normal working temperature rise test, abnormal temperature rise test, component effectiveness test, leakage current test, fire test, ball pressure test, etc.
Of course, the safety certification test mainly considers the safety aspect of the product, but as long as the certification can be passed, the quality of the product is limited to a certain extent. Therefore, the quality of truly certified products is still guaranteed.
In fact, no matter which country’s certification is, its standards are transformed by the national standardization organization IEC, so the product performance is basically the same. It's just that different countries have different voltages and plugs, just adding some tests on the basis of the IEC standard. The reasons for the difference in the price of power supplies with different certifications are: the price of the housing and the cost of certification.
