Data cables are used to connect mobile devices and computers to achieve data transmission or communication purposes.What are the categories of data cables and how do we choose to buy the data cable?Lets take a look with Xiaobian!
Data cable classification
Classified from functions: Internet cable, flashing line, synchronization line, charging line, multi -functional line
Internet line: It can only be used for GPRS or CDMA 1X to access the Internet.
Brush: It can only be used to upgrade the flashing.
Synchronous line: It is used to transmit telephone books, pictures ringtones, SMS, multimedia data, etc., there are two -way transmission and one -way transmission, which is more common.
Charging cable: Generally, a USB charging function is added to the Internet or synchronous line, which can be subdivided into two types: charging and charging switch.
Multi -functional lines: support 2 or more functions such as Internet, synchronization, flashing, charging.
Classified from manufacturers: original original, domestic brands, domestic unlicensed
Original original
The mobile phone manufacturer is directly produced or provided by the material to entrust a manufacturer of manufacturers. The brand of mobile phone is the best quality and the most expensive.
Domestic brand
The data cable has its own brand, and the manufacturers address and telephone number is printed on the packaging. It is more formal, good quality, low in price, not much.
Domestically -made unlicensed
There is no identifier manufacturer and brand.Divided into 2 categories. The first is the data line of professional exports. The quality is very passing. The price is still lower than the domestic brand brand, the most cost -effective; the second is the miscellaneous line, the price is very low, and the quality is poor.
How to buy data cables
1. Soft and hard
High -quality data cables are relatively soft, and inferior data cables are often harder.Therefore, the soft line is often more durable and easy to store. For a long time, it may not be able to charge or pass data.
2. Interface
The most bad data cable is the interface at both ends, so the interface is important when choosing the data cable.The high -quality data cable adopts an integrated suppression process, exquisite workmanship, small and durable, soft texture texture, and close coordination with the cable.
3, length
The qualified data cable should not have a great impact on the transmission speed within a certain length range.Therefore, the length of the data cable depends on personal needs.
4. Loose
When buying, you can try it first to see if the plug is easy to use.For inferior data cables, the mobile phone interface is a bit tight, or it is very loose.It takes a long time in this way, it is not good to the mobile phone socket, and it is easy to damage the socket.
5. Inner core
Good data cables use thick high -quality copper cores, which can pass a large current to ensure fast charging, less heat, and more stable transmission.Because the inner core cannot be seen directly, when buying, you should try to choose a data cable with thick wire diameter, heavy quality, and harder wires.
6. Packing
See if the packaging is exquisite, whether there is a clear place of origin, production date, manufacturer telephone, address, qualification certificate, etc.The disadvantaged data cable is often poorly packed, without the production logo, and the manufacturers address is ambiguous.
7. Brand
The biggest key to buying data cables is the brand. If possible, try to buy the original products as much as possible.In addition, no matter how high price product manufacturers, there will be a certain failure rate, but the more qualified and good merchant failure rate will be lower, more services that users can enjoy.More perfect, buying is more assured.
What should I do if the data cable is connected to the computer and can only be charged
1. Not opening the smart USB mode
If this is the case where the mobile phone assistant is installed, turn on the mobile phone settings -developer options -check "keep wake -up and USB debug" and enter the next step according to the prompts.
2. Uncontured mobile phone assistant software
Computer anti -virus software generally detects mobile phone data automatically, and prompts to open: USB debugging and keeping awakening function.According to the prompts, the next step can be used.
3. Unpacking data cable
Under normal circumstances, the mobile phone data cable is common, but except for individual mobile phones, this will occur.Therefore, the original data cable must be collected to prevent similar phenomena.
4. The mobile phone may be medium virus
At this time, it is necessary to pass the anti -virus software for anti -virus, and then continue to connect.When the mobile phone cannot completely kill the virus, you can directly find the after -sales service for anti -virus and find out the reason.
5. The problem of the mobile phone itself
General mobile phone players are basically unable to solve themselves, and they need to find mobile phone maintenanceers for maintenance.
6. The problem of mobile data cable interface
If you use the same data cable to test the normal mobile phone, the charging is still displayed, and the computer cannot be connected.It means that it is a problem with the data cable. You can try to change a new data cable for secondary connection.
