Comparison and evaluation of soft and non winding breakthrough type C data cableComparison and evaluation of soft and non winding breakthrough type C data cable

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.

Cable and manufacturer information.

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 cable.

Close up of head a.

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.

The 360 Sony line is 109.2 milliohm. Although this line is the shortest in length, it is worth affirming for an assembly line, which also shows the strength of my wiring.

Well, after the three lines have been tested, from the perspective of internal resistance, the breakthrough line is still far behind by the other two lines, but it is not as simple as you think. Let's take another look at the following charging test:

Breaking through the line charging power, you can see that due to the convenience of the type C port, we can test the charging power on the mobile phone when testing the charging of the type C mobile phone. The test results here are the actual charging power of the mobile phone, and the difference between the test and the test without a meter is very small, almost negligible. The advantage of testing on the mobile phone is that the data obtained from testing on the charger is closer to the real charging rate of the mobile phone.

The charging power of newhail line is almost the same. Isn't it said that the smaller the internal resistance is, the smaller the loss is? Why is the power similar? We'll talk about that later.

The charging power of 360 Sony cable is almost the same, and the power received by the mobile phone is about 15W.

So the question is, why? In fact, we can see the reason by looking at the voltage. The breakthrough line resistance is large, and the voltage to the mobile terminal is relatively low. But now the charging of mobile phones depends on the power. I don't want to reach the power I want, so I increase the charging current to make the power reach about 15W. If you look at newhail and 360 Sony lines, the voltage is relatively high, because the loss is low, so the current is slightly low, and the total power is still 15W.

However, this does not mean that low internal resistance is useless. When high current is used, the advantage of internal resistance will be obvious. However, in the case of small current devices such as mobile phones, coupled with the improvement of mobile phone charging algorithm, the shortcomings of breakthrough line have not affected the charging rate of mobile phones at all. On the contrary, its flat design, soft and non winding features will make it more people's choice. The internal resistance of newhail cable material is quite good, but too thick wire diameter and hard design make it difficult to get the love of mobile phone users. It can be used in fixed high current equipment.


Finally, I will choose breakthrough line as the charging line of mobile phone, just because it is soft enough, flat design is not easy to wind, and the C head design is very short. These advantages easily make breakthrough line become the data cable of mobile phone and other small current devices. By the way, I would like to praise the 360 Sony line I made, which performs well.
