And because the voltage is not equal, it may damage the model. I once bought a 9.9 free shipping cable on Pxizi, and it wasn't long before my phone was sent to be repaired. At present, most of the relatively cheap data cables sold on the market come from Huaqiang North, and most of them are made of scraps and some relatively poor quality raw materials. There are often problems with charging failure or slow charging, and some serious leakage will occur. But there are some although the brand is not a famous brand, but the quality can be, such as green link, millet and Rome Shi, these brands are tried out by others, for the small white to buy the data line does not need to understand too much principle, as long as the data line is durable, and these brands are relatively well-known because of the use of more people, durable, so the word of mouth naturally comes out. But I recommend you a I accidentally found a brand data cable - BSI flash series two drag three fast charge data cable, do not know, a good thing with the next jump.
Huaqiang North data line to number millet data line is the most popular
