wholesale 2 in 1 multi-function retractable cable 1m usb data sync charging data line

wholesale retractable charging cable

It is provided with scrub two-in-one stretch basket data line and new pure copper core, which is matte texture. Environmentally friendly TPE and TPU outer sheath has fine workmanship, comfortable feel, two-color matching, novel design. The interface adopts the form of adapter, which can be freely extracted, convenient and practical. With a professional team, modern technology equipment and mature craftsmanship, the product is improved in every detail.

The cost of manufacturing the Android data cable is very low, but the iPhone data cable is different. A regular Lightning data cable needs to be equipped with an official Apple-certified security chip, which can play a great role in protecting the device. The data cable with the Apple chip is built-in, and it is called the MFi certified data cable. However, due to increased manufacturing costs, third-party MFi data cables are generally much more expensive. Obviously, cheap two-in-one data cables are not MFi certified data cables (MFi certified data will be marked). Once you use these uncertified data cables, you will not be able to charge at least, and you will burn the phone. The Apple official also has a clear stipulation that Apple will not provide any warranty service for damage caused by the use of unauthorized accessories.

Copper has good electrical conductivity and is widely used in industry. Most of the wires are made of copper wire. The same is true for data wires. This production and processing data wire uses pure copper cores. (All copper core) is a copper wire drawn from a pure copper rod. The material is single. The surface and the inside are all copper metal. The appearance used to be yellow. The color is darker and lighter due to the purity of the copper. In terms of physical properties, it is bare. The copper wire is soft and has excellent electrical conductivity.

The load power of copper core wire is much greater than that of aluminum core wire. For example, a copper core wire and aluminum core wire that are also 2.5 square meters, if the aluminum core wire can load 1000 watts, then the copper core wire can load at least 2000 watts. Therefore, when we choose to buy wires, it is best to buy copper core wires, because the load rate of copper core wires is relatively large, and it is safer to use.

Copper core wire and aluminum core wire are relatively softer than aluminum core wire, but what I mean by softness is not hardness, but flexibility. The copper core wire will be more resistant to bending and will not be easily broken, while the aluminum core wire will easily be broken when it is bent.

The stability of copper core wire and aluminum core wire is also different. In the same environment, aluminum core wire will oxidize faster than copper core wire, which will also increase the resistance inside the wire, making the whole wire The temperature rises, thereby reducing the load rate of the wire. The copper core wire will be relatively stable, and it will be less prone to safety issues.
