Look at the material, specifications and certification marks

At present, there is no national mandatory safety standard for charging data cables in my country. This is because the previous charging data cables were all below the safety voltage. However, with the rapid development of fast charging chargers, related technologies are also at the forefront of the world, resulting in the inability of safety standards to keep up.

Ms. Ni, a charging equipment seller at a mobile phone market in Nanjing, said: "Once a customer asked me to send a set of fast charging equipment, but did not tell me what brand of mobile phone he had. As a result, I took it back and it did not support it, and the charger was broken. When buying a data cable, you must specify the model of the mobile phone and whether it supports fast charging."

When consumers purchase charging equipment, they should first look at the material. Generally, they will choose PVC and TPE materials with strong flame retardancy. Second, the output specifications of the charging cable, terminal and charger should be consistent to avoid overload. Third, they should purchase products with CQC certification and produced by regular manufacturers.
