Nowadays, mobile phones have become our soul mate, we cannot do without phones, but the most horrible thing is that when the phone is out of power, and at this time, a data usb cable will solve our troubles.

So today, Lito Melody will let you know-how to choose the right mobile phone data usb cable?

Wire:

First, the usb charging cable is divided into two parts, the inner "wire" and the outer "insulation".

According to the physics principle, when the current is constant, the thicker the wire, the larger the current that can be passed, and the faster the charging will naturally! So, as the internal material of the conductor, the thicker the better!

At the same time, the good quality data usb cable will be added with a layer of aluminum foil shielding and metal woven mesh to make the charging and transmission process more stable. So a good data charger cable will be thicker.

However, it is not excluded that some factories will reduce the quality of the data usb cable - two data cables of the same thickness, it is possible that the insulation of the A data usb cable is very thin, but the wire inside is very thick; and the quality of the wire inside the B data usb cable, In fact, it is very bad, just making the insulation is very thick.

Therefore, it can only be said that the data charging cable will not be too thin; too thin data charging cable will certainly not be good.

Length:

We always want the usb charging cable to be long and long. It is best to have a data usb cable around the whole house! Then we can watch movies or playing games while charging.

However, if the charging cable is too long, it will cause bit errors due to the cable noise, affecting the rate of data transmission.

At the same time, the long data charging cable also represents the large line resistance, and the current loss is also more. So in fact, the shorter the data charging cable, the higher the charing efficiency.

If the material of the data line is the same, in the same environment, the shorter the data charging cable, the faster the charging speed, because the shorter the length, the smaller the resistance; on the contrary, the longer the data charging cable, the larger the resistance, the charging the slower the speed. So if you are wondering the speed of charing, then you need to think about it.

Interface:

The interface of the data usb cable is mainly composed of a housing and a contact. The current data charging cable will be coated with a thin layer of gold on the contacts to extend the insertion and removal life of the data cable, preventing the contacts from being oxidized and causing unstable transmission. For a good quality data cable, the thickness of the gold plating is generally thicker, and the general data cable is generally thinner.

Therefore, everyone can make a reference according to the thickness of the coating. Gold plating has no effect on the charging speed, but solves the problem of stability and longevity.

At the end, it is generally better to choose a thicker, shorter data usb cable, and buy a branded product with quality assurance.
