Comparison and evaluation of soft and non winding breakthrough type C data line
With the growth of the consumer electronics market, many traditional electrical appliance manufacturers have begun to join the market. Breakthrough is one of them. The most common breakthrough in the past was breakthrough arrangement. Now breakthrough has begun to seek its own breakthrough. It has begun to enter the consumer electronics market and launched many products with high cost performance, Let's take a look at the breakthrough USB type-C cable.

Take out the wire harness and use flat design. My first feeling is that it is soft. I really feel very good.
Head a absorbs magnetism, and head C slightly absorbs magnetism. The length is 127cm, slightly longer than the general 1m data line.
C head close-up, C head for full contact, but for a to C line full contact is not very useful, but also can see the attitude of manufacturers.
Let's make a comparison of three AC wires. The other two are the braided wire of newhail, 1m in length. The other is the AC wire I combined with 360 and Sony wires, about 80cm in length.
First talk about the intuitive feeling of the next three lines, and then test the internal resistance and charging.
The first feeling of breaking through the line is softness, really softness, very softness.
Now we start the internal resistance test, because the four wire method is used, so the accuracy is still very high, which can be used for reference.
Breaking through the 252.9 milliohm line, I think that typec has four current contacts. This internal resistance is actually not small.
The newhail line is 109.2 milliohm, which is not as good as the powerful Huawei 5A line's 60 milliohm, but the data is really good. You can also feel that the material used for this line is sufficient by looking at the wire thickness.
360 Sony line 109.2 milliohm, although the length of this line is the shortest, but for an assembly line, the results are still worth affirming, which also shows the strength of my wiring.
Well, after the three lines are tested, considering the internal resistance, the breakthrough line is still left behind by the other two lines far away, but the matter is not as simple as you think. Let's look at the charging test below:
The charging power of breakthrough line can be seen because of the convenience of typec port. When the mobile phone of typec is tested and charged, we can test the charging power on the mobile phone. Here, the test shows that the actual charging power of the mobile phone is very small, which is negligible. The advantage of testing on the mobile phone is that the data obtained by testing on the charger side is closer to the real charging rate of the mobile phone.
The charging power of newhail line is almost the same. Is it not that the smaller the internal resistance is, the smaller the loss is? Why is the power similar? We'll talk about it later.
The charging power of 360 Sony line is almost the same, and the power received by mobile phone is about 15W.
So why is that the question? Actually, the voltage can be seen. The voltage that breaks through the line resistance is relatively low. But the current charging of mobile phones is based on power. I can't reach the power I want. So I can improve the charging current to make the power reach about 15W. The voltage of newhail and 360 Sony line is relatively high. Because of the low loss, the current is slightly low, and the total power is 15W.
But this does not mean that the internal resistance is low and useless. The advantage of internal resistance will be obvious when using large current. However, the shortcomings of breaking through the line have no impact on the charging rate of mobile phone by adding the improvement of mobile phone charging algorithm in this small current device. On the contrary, its flat design, soft and non winding characteristics will make it more people choose. The internal resistance of newhail wire is quite good, but the rough wire diameter and hard design make it difficult to get the love of mobile phone users. It can be used on fixed large current equipment.
Finally, I will choose the breakthrough line as the charging line of mobile phone, only because it is soft enough, flat design is not easy to wrap, and the c-head design is short. These advantages make the breakthrough line become the data line of small current devices such as mobile phone. By the way, I will boast that the 360 Sony line I made has performed well.
