Why are some mobile phone data cable prices different
Why are some mobile phone data cable prices different?
The price of the data cable is affected by many factors, let's talk about the coating on the plug first. In general, it is stainless steel or nickel-plated, etc., in order to prevent the contact part of the plug from oxidizing, resulting in poor contact, and will not have a great impact on the output speed.
In addition, the thickness of the coating on the plug of the data cable of different prices can even be 10-20 times different, and it must be greasy to sell cheaply. Many people think that the original data cable of the mobile phone is the best. In fact, this is a misunderstanding. Some cheap mobile phones will still use a not very good data cable to save costs. It may be better than the cottage, but it is definitely not good.
After talking about coating, let's talk about the difference of wire. The wire determines the basic performance of a data line. A good data cable separates data transmission and charging. The inferior data cable doesn’t care about any interference at all. Just put the cable there. When we use it, the interference between the cables will be very large, which will definitely affect the speed. This is why cheap data cable charges slowly. The reason, and even more, can not transfer data while charging.
In terms of cost, inferior data lines will not use pure copper as the conductor and may choose lower-cost aluminum-clad copper or other alternative materials, which will also greatly affect the transmission efficiency. Even if they used pure copper, they would be very, very fine.
A lot of cheap data cables will cause serious charging and heating, and even cause fires due to cheap USB cable.
