If you can not identify can not charge, it is necessary to repair. If you can recognize and charge, replace the data cable and the charger (the original estimate is also damaged). . and then look at the voltage is not too low, not only to the maintenance station to repair, and pay attention to the iPad and iPhone do not mix the power adapter, the voltage is different.

Q:Wire and cable model ZD what does it mean

Wire pipe water problem: In fact, this problem is very serious, then this line should be scrapped or replaced, if you continue to reluctantly use not only to bring you the safety of trouble and the insulation of the wire dropped sharply! Because there is water it will lead to internal leakage can also make the wire heat caused by wire burning and trivial trivial accident, so be sure to take the necessary replacement! Supplement: the wire out of all, with the wire to grab the absorbent gauze and the like back to the twitching, many times for the gauze to dry the water, hair dryer toward the tube to heat the tube to dry and then re-layout of the new line.
