How to better buy a 3-in-1 charging cable

There are several reasons for the slow charging of the three-in-one data line. One is that the quality of the wire is not good, and the loss is too large because it is too fine. The voltage reaching the mobile phone is too low, and the charging control circuit will reduce the charging current. The second aspect is due to three interfaces integration on one of the line, if three interfaces charge their phone at the same time also can reduce the charging current, in addition to prevent due to different agreement charging mobile phones at the same time insert three interfaces and high damage output cell phones, some of the more than one data line will be removed in the middle of the cable, only keep the power supply line, or that the sub cable, etc. In this way, there is no correct protocol identification when different mobile phones are charged, resulting in the reduction of charging current and affecting the speed of charging.

Choose charging data line, as far as possible or choose the original line, the latter third party quality or certification line, charging head should also choose the regular manufacturers produced, so as to ensure the speed of charging, not easy because of voltage output quality and other reasons caused by mobile phone interference and other problems.
