When we buy a new mobile phone, we usually send a data cable, but often the data cable is short, we will buy a longer spare, used for bedside charging, office charging and so on, after all, the data cable is too short really affect the mood of playing mobile phone.
So with different lengths of data cable, 1 meter and 3 meter cable charging and transfer speed is the same? What about data lines of different thicknesses? Do length and thickness matter for charging and transfer speed? Today we are going to talk about the thickness of the mobile phone data cable and the charging speed of those things!
2, the thinner the data cable, the slower the charge?
Theoretically speaking, thicker data line will indeed be more thin data line capable!
The resistance is related to the cross section of the Wire. The internal wire unit of the data wire is AWG, which represents American Wire Gauge. The smaller the value behind it, the thicker the diameter of the wire, the larger the electric flow it can carry, and the faster the charging speed.
Specifically, it can be simply understood as water discharge from pipes. In the same case, thicker pipes will flow through more water. If the pipes are too thin or too long, the transmission speed will not be very good.
So with all that said, how do you choose the right data cable?
First of all, we should choose according to the actual use scenario of the data cable.
For most people, the mobile phone data cable is used to charge, transmission of data is not very useful, in this case, according to the need to choose: dormitory or bed, you can choose 2 meters or longer; Spare in the bag, 25 cm short thread will do; For the office, one meter or 1.5 meter is just fine.
In theory, under the premise of qualified quality, choose the thicker kind is OK, as long as it is not particularly long (more than 5 meters), charging speed is not a big impact.
If your cable is primarily used to transmit data, that's a different story. On the premise of ensuring quality, choose a thicker or shorter transmission data will be better, after all, for the transmission of data, using too long data wire to transfer data, too slow speed can be maddening.
If the wire is not good, the wire diameter is small, even if the length meets the requirements, the transmission performance will be greatly reduced, and even the data line fever, it can be a mess.
To sum up:
The length and thickness of the data cable have an impact on charging and transmission speed, but simply for charging, the impact is not large, can be ignored; For data transmission, it is better to choose the shorter and thicker type.
From the use efficiency, of course, is the original charging set is the best, if you want to choose to use the third party data cable, as far as possible to choose some big brands, look at its specific parameters, especially Apple users, but also to choose those through MFi certified products.
