For those of you who are used to mobile phones, the mobile phone data cable is probably the most familiar thing (it is better to be inseparable 24 hours a day). But the things that are most familiar are often the most unfamiliar. For example, do you really know your data line? It's totally different from your imagination. After the data line is deformed, it is enough to surprise you!
1 interface
Let's start with what we are most familiar with. Which mobile phone do you use? The data line interfaces used by different mobile phones are actually different. For example, the lightning port of apple mobile phone, micro port of ordinary android phone, and type-c interface which emerged in recent years, you should never think that just buying a data cable will work, use the lightning port of apple to charge the phone of type-c interface... You think too much?
2 specifications (shape)
What can a data line look like? We are generally accustomed to prefer the official standard data cable, but they are always too long or too short to be satisfactory. If you are still complaining that the data line is too single, then you are really wrong.
Take the metal data cable as an example, the length can be from 2 meters to 0.25 meters. What is the concept? From the height of your height to the width of an A4 paper, you have everything.
If this is still too long for you, then there is a key deduction, usually guest a key chain, when necessary, it can be used, but also worry about the problem of forgetting to bring the data line?
3 functions
Mobile phones are differentiated from fast charging, and charging heads are also divided into fast charging and non-fast charging. Then, is there any difference between fast charging and non-fast charging in the data line?
Strictly speaking, the data line does not have the difference between fast charge and non-fast charge, but there is a difference between input and output current. If a data line can only support 1A current, even if it is charged with a 2A charger, the speed is also It will be largely suppressed, and it will also be very harmful to the data line itself.
The current chargers have basically reached 1.5A or 2A or more, basically supporting 2A is a large current charging. This can be carefully identified at the time of purchase.
4 Brand
This one is obvious. There are so many brands on the market that it is dazzling. How to choose the data cable that suits your mobile phone?
Data lines can't be bought indiscriminately, You can't buy unbranded data. We all know this. How to choose? In addition to the brand data line, the easiest way is to search the data line when you buy online, and choose the best price for you in the most popular ones.
5 Number of interfaces
In addition to our common single-head data line, the number of interfaces can be dragged two, three, four, seven or even ten... You can't do it without them.
Is the data line of this kind of much head good? There's a lot to say.
On the one hand, this kind of data line can make many devices charge at the same time. On the other hand, the charging head is rated current. When so many devices are charged at the same time, the current divided by each device is bound to be extremely limited.
Continue to give examples: The teacher has 10 sugars in his hand. Only you are alone. He gives you all the sugar. At this time, the other 9 students are back. See you for a share, so each of you has There is only one sugar.
However, the writer is talking about a special one-to-two data cable. They are not connected to several mobile phones at the same time, but functions such as "Android Apple Universal". Yes, there are two data cables at the same time. Different interfaces.
This kind of data cable can be considered. Think about the mobile phone with two interfaces at the same time. You can only go out with one data cable when you go out next time (after all, the probability that two mobile phones have no power at the same time is relatively small). Think about it, there is still a little excitement.
In fact, the data line has some other differences, such as apple's MFI certification, qualcomm's QC certification, data line material and thickness and a series of things. In the final analysis, just like the mobile phone, the decision to use a data line is also determined by the quality and after-sales service of the brand in addition to the above functions and categories. After all, we buy things for ease of use, not for inconvenience. What do you think?
