Heavy metal
The solder joint between the wire and the interface, the data line of the leather wrapped around the wire, the button and other parts may contain heavy metal lead and chromium. The data line is often touched by hand, even by children, which is extremely easy to cause lead to enter the human body.
Fracture
The data line is often bent, and the connection between the wire and the interface is easy to break, and the small parts that break are easy to be eaten by children.
Short circuit
The copper wire inside the inferior data line is very thin, which is easy to break during use, causing a short circuit, affecting the safety of the charger, and even burning. And the use environment of the charger is often at the bedside, and it is extremely dangerous if the fire occurs.
Affect mobile phone battery
The copper wire inside the inferior data line is slender, not even pure copper (such as enameled wire), which causes a large resistance value. The power supply itself consumes more, which may cause the charging speed to slow down or even charge.
