1, consider whether there is a problem with the charging cable, and find another charging cable. When we buy a charging treasure, we always have a charging cable as standard. When we find that the charging treasure can't be charged, we must first check whether the charging cable is broken. The easiest way is to compare the data cable that comes with the phone. But this kind of situation generally rarely happens.
2. Check whether the USB charging interface is plugged in firmly. The USB interface is very tight for the first time. In addition, you can replace the data cable, or other mobile phones can try again to see if it is normal, or you can charge the mobile power supply for a few minutes and try again.
There may be something wrong with the charger itself. For example, if the external output current of the charging head is too small, you can try to connect a computer to charge it, or you can try to charge the head with a larger current of 2A. Some charging heads will fail if they are used for a long time. It is recommended to replace the charging head and keep charging for more than 6 hours.
