The thinner the cable, the slower the charge?

It's true that thin charging cables charge more slowly than thick ones

The unit of the internal Wire of the data cable is AWG, which stands for American Wire Gauge. The smaller the value behind it, the larger the Wire diameter, the larger the current it can carry, and the faster the charging speed.

Specific you can refer to a large straw and a small straw "workload".

In addition, the material of a data wire core is mainly divided into tinned copper, aluminum magnesium wire, enameled wire, copper wire, copper foil wire, bare copper, galvanized iron core and iron core and so on.

Picking up our physics knowledge, metal conductivity ranking is silver > copper > aluminum > iron > zinc > tin.

Therefore, the data line with silver and copper plating is basically high-end, followed by tinned copper, bare copper, or aluminum magnesium wire, enameled wire, copper foil wire, and then go to the lower level may be copper core plating, iron core galvanized, steel clad steel, ladle iron and so on.

So when you buy the data line, you can also take a look at the product introduction page which lists the material and data of the core of the data line, which is also to increase your knowledge.

In addition, now many businesses will cover the data line with metal braided mesh and a layer of aluminum foil shielding layer, which can not only improve the charging and data transmission efficiency, but also enhance the pull-out performance of the data line.

Of course, there will also be some unscrupulous merchants will falsely thicken the skin of the data line to show the thickness, we should not be easily fooled when buying.
