The thread is broken and charged for 1 hour until it reaches 10%. This is a problem we often encounter when using the charging cable. More serious is, for example, charging your own mobile phone, charging causes spontaneous combustion and other accidents. How to choose a beautiful and safe data cable, away from the harm caused by the copy products, there are five points to note:

Slow charging

The charging speed depends on whether the charging performance of a charging cable is strong. It depends on the input voltage and voltage drop when the current is applied. In other words, it depends on how much power is there when the current passes through the charging cable. The loss is related to the impedance of the core. At present, some copy charging cables on the market, the current is extremely unstable, and it is easy to consume the battery life of the mobile phone.

Slow transmission speed

Some people think that the length of the data cable will affect the transmission rate. In fact, within a certain length range, the length of qualified data cables will not have a great impact on the transmission speed. Most of the copy charging cables on the market have only 2 cores, and the original USB data cables use 4-core copper wires to support data transmission. And charging. In addition, the diameter of the line will actually affect the charging and data transmission speed of the mobile phone. If the wire is not good and the wire diameter is small, even if it is a regular length data cable, its transmission performance will not be very good. There may even be cases where the data cable is hot, causing a safety hazard.

Easy to break the thread

There are many reasons for the wire breakage, such as poor wire quality, overheating of the core, and long-term winding. When purchasing, it is best to choose some fine craftsmanship. The original data cable uses a high-purity copper core with a foil shield to greatly reduce heat loss while increasing charge and data rates.

Unstable current burnout hardware

The investigation found that the copy data cable is likely to destroy an important chip in the phone due to the unstable current supplied. This chip is responsible for controlling the charging voltage, power button, USB function, and so on. After being destroyed, the phone will not boot. The professional charging cable will generate a limiting voltage when the current is too large, protecting the mobile phone from damage.
