According to news on May 12, charging cables are essential for mobile phones and other electrical appliances, and many people will have more. But if you buy a cheap charging cable, be careful, it is recommended to unplug it as soon as possible. China Fire Department issued a document saying that when Mr. Zhai from Hebei was working, white smoke suddenly came out of the mobile phone charging cable and the charging port was deformed, and he said that the cable was not original. Previously, CCTV's "Weekly Quality Report" experimented with a variety of charging cables on the market and found that there are 4 wires inside the general charging cable, and the high-quality cable has 9 layers of wire cores and protective structures, and the materials are good. Due to cost problems, inferior wires do not use qualified flame retardant materials, and cannot be automatically extinguished and assisted in combustion in case of fire; Poor corrosion resistance, serious rust in salt spray test, easy to cause poor contact or short circuit; Moreover, there is no metal steel sleeve at the interface, which is easy to tear. Fire protection reminds that don't be greedy for cheap charging cables, but look for regular brands.
