With the continuous iteration and development of digital devices, the fast charging power is getting higher and higher. Consumers have gradually discovered that different data cables often provide different charging power to devices. Original cable or third party?
With the continuous iteration and development of digital devices, the fast charging power is getting higher and higher. Consumers have gradually discovered that different data cables often provide different charging power to devices. Original cable or third party?
Cable length, cable material, and cable price are all factors that affect the choice. The selection of data cables should first look at their own needs, and then choose according to the usage scenario and other conditions.
Composition and importance of data cables
Data cables are composed of wires and insulation. Thick wires can carry larger currents and speed up charging. For wires, the thicker the better, because thick wires can carry larger currents, thereby speeding up charging. In addition, high-quality data cables will also add aluminum foil shielding layers and metal braided meshes to ensure the stability of the charging and transmission process. Therefore, good data cables are often relatively thick.
Data cable quality judgment
However, there are also some bad merchants in the market who may deliberately make the insulation of the data cable thicker, while the internal wire quality is very poor. There is a behavior in the market that deliberately thickens the insulation to cover up inferior wires, so we cannot judge the quality of the data cable based solely on its appearance. It can only be said that a good data cable will not be too thin; and a data cable that is too thin is often of poor quality.
▲ Impact of data cable length
Regarding the length of the data cable, although the lengthened data cable provides convenience, it increases the line resistance and line noise, affecting the charging efficiency and data transmission speed. Although the lengthened data cable (such as two or three meters long) provides convenience for certain activities, such as playing King of Glory while charging, the overlong data cable will increase the line resistance, which in turn affects the charging efficiency. At the same time, the overlong data cable may also cause bit errors due to line noise, reducing the data transmission speed. Therefore, while pursuing convenience, we must also weigh the impact of the length of the data cable on the charging efficiency and data transmission.
Interface design and stability
The interface part of the data cable is mainly composed of a shell and a contact. The data cable interface consists of a shell and a contact. The gold plating of the contact can improve the plug-in life and stability. The gold plating thickness of the high-quality data cable is thicker. At present, the mainstream data cables on the market are covered with a thin layer of gold on the contact, which is designed to extend the plug-in life of the data cable and prevent the contact from oxidizing, thereby ensuring the stability of charging and transmission. High-quality data cables usually have thicker gold plating thickness, about 50 microns, while ordinary data cables may only be covered with a very thin layer of metal.
Purchase and use suggestions
- Make sure to purchase genuine charging cables from regular channels to ensure quality and safety.
- Select matching and high-quality adapter charging cables to ensure charging efficiency and stability.
- Do not charge in an overheated environment to prevent safety hazards such as explosion or fire.
- It is recommended to purchase high-quality products from well-known brands through regular channels to improve the user experience and safety.
- Avoid overcharging the power bank for a long time to prevent overcharging and affect the service life.b
