Among all the mobile phone accessories, the data cable is the most inconspicuous, but it is now becoming more and more important. Mobile phone charging uses USB data for charging. At present, almost no mobile phone supports removable batteries. Power has become a big concern for people, so that some business people suffer from power phobia because of this. The function of transmission has become a subsidiary function, not so much a data cable as a charging cable. The initial USB power supply standard stipulates that the maximum current of 500mA is specified, which obviously cannot meet the requirements for fast charging of mobile phones. In terms of data transmission, the 2.0 standard is adopted, and the data transmission rate can reach 480Mbps. At such a high rate, the data cable is required to have The shielding layer, and the cross-sectional area of the wire should be increased accordingly in order to reduce the wire resistance. When charging, only two power cords in the USB cable are used, and the battery capacity of the mobile phone is getting larger and larger, so what kind of data cable is easy to use?
The most direct reason for the quality of the data cable is the difference in the quality of the cable. Some USB cables have very thin wires and large cable resistance. When charging, a lot of power is consumed early on the wires, wasted, and the charging time is slow. .
The IPSKY USB-C game braided data cable solves all the problems of the data cable very well. In terms of color, two colors of red and black are provided for different users to choose. The length is 1.5 meters. If you use Type-C equipment, it can be used.
From the appearance point of view, the outer skin of the data cable adopts a braided layer made of multiple strands of high strength, which can resist bending and tension. Even if it is used for a long time, it will not break due to external aging.
The IPSKY USB-C game woven data cable can carry a large current of 3A and fully meets various fast charging protocols. As long as the charger and device support it, the IPSKY USB-C game data cable can support it.
In addition to the above-mentioned material factors, the advantage of this data cable lies in the design of the Type-C interface, which is a right-angle design. The special meaning of calling it a game data cable lies in two aspects: 1. Elbow design, for most The layout of the charging port at the bottom of the mobile phone will not cause interference while charging while playing games or watching videos on the horizontal screen of the mobile phone. 2. Due to the low cable resistance and low line loss, the charging efficiency is higher than that of ordinary data cables. The heat is also small.

The outer wrapping of the woven material can effectively improve the tensile strength and bending resistance of the data cable, even if it is clamped by the drawer, it will not cause damage.
Compared with the common straight-port data cable, the right-angle data port has the advantage of protecting the charging port of the mobile phone. If it is charged in the bag, the length of the ordinary port is too long. If the cable is subjected to external force, the power is easily transmitted to the port. If it damages the interface, the force on the right-angle elbow is much smaller.
Of course, we still speak with data to test this data cable. We use a 65W fast charging source and electronic load, a USB analyzer, and a common data cable for comparison.
The first is the fast charge test. Connect the IPSKY USB-C game braided data cable for the mobile phone to the charger, and you can see that the fast charge protocol is in effect. The current charging voltage is 9.42V and the current is 1.79A. The charging power is close to 20W.
Now we connect two USB analyzers to both ends of the data line and use an electronic load to test. When there is no load, the power supply voltage is 5.21, and the Type-C terminal displays 5.1945V. Due to the display accuracy, these two values are Within the reasonable measurement error range.
Connect the electronic load, adjust the load current to 1.1A, the power supply voltage is 4.87V, the Type-C terminal voltage is 4.6068V, that is to say, under 1.1A current, the line loss of IPSKY USB-C game braided data cable It is 0.27V.

Now we look at the ordinary data line, the uniform current, the line loss has reached 0.52V.
This is 0.49V under 2A current.
The ordinary data line has reached 0, 74V.
Replacing the electronic load with a mobile phone can also explain the problem. Start fast charging, the current is 1.76A, and the line loss is 0.4V.
The normal data line starts fast charging, the current can only reach 1.63A, and the line loss is 0.63V. When the current drops, the loss on the wire increases. The quality of the material inside the data cable is obvious.
Many students don't understand what this means, so let's test the temperature with an infrared thermometer. Half an hour after starting the fast charge protocol, the temperature rise at the Type-C interface is 30 degrees Celsius.
The interface temperature of the ordinary data cable is close to 36 degrees after half an hour, which is a bit hot.
Through this test, it is not difficult to see that the pros and cons of the data cable do have a greater impact on charging. A high-quality data cable can add the power of the charging head to the mobile phone to the greatest extent, reducing additional losses, and from time to time. In other words, it can shorten the time required to fully charge; from an economic point of view, if inferior quality data lines are used, more energy will be wasted in the form of heat. Finally, due to the high-quality cable, the contact resistance at the interface is reduced, the heat generation of the mobile phone interface is also small, and the life of the interface will be extended. You must not use a low-quality data cable to charge, otherwise, the charging time will become longer and waste time, not to mention, the serious will cause the interface to heat up and damage the mobile phone charging interface, and the serious will also cause a safety accident.
