I put the data line opened, want to extend the data line charging at the bedside, data line there is a layer of metal mesh, the thick black line is connected with the data line and the data line, I use ordinary enameled wire extension, only extended red and black, can be a normal charge, but the layer of metal mesh is used for what? For the field? I extend the data line feasible? Long-term use will not be on the screen of the mobile phone battery or what impact, please explain the ropes,
Metal mesh is used to shield the surrounding electromagnetic interference, such as cell phone signals, WiFi, etc., to protect the quality of the signal transmission cable
In short, the anti interference, but also more solid. Generally do not have any effect, if you are in the vicinity of a strong magnetic field may be a bit of use, the general data line is the transmission of electrical signals, their ability to resist interference is relatively strong, unlike television antennas, such as. Oh, I understand. You're curious
The charging cable does not need to be shielded, only the extension is no problem, the signal cable needs to be shielded, especially the earphone, the sound and the like
