can not
There are several reasons why it cannot be charged!
1, consider whether there is a problem with the charging cable, change a charging cable to see. When we buy a charging bank, we will be equipped with a charging cable. When we find that the charging bank cannot be charged, we should first check whether the charging cable is broken. The easiest way is to compare the data cable with the mobile phone. But this is rarely the case.
2, check whether the USB charging interface is firmly inserted, the first use of the USB interface is tight. In addition, the data cable can be replaced, or other mobile phones can try again to see whether it is normal, and you can also try again after charging the mobile power for a few minutes.
3, there may be a problem with the charger itself, for example, the external output current of the charging head is too small, you can try to connect the computer to charge, you can also try with a larger current 2A charging head. After some charging head is used for a long time, part of the fault will not be charged, it is recommended to replace the charging head and keep charging for more than 6 hours.

4. Is the charging treasure useless for a long time? Do not use mobile power for a long time, it is best to retain 50% of the state of power storage, if not, it is easy to break for a long time. In addition, it is recommended to charge the mobile power before using it for the first time, and it is not necessary to charge the lithium battery to full charge, let alone apply the power to run out. It is best to store the mobile power supply in a mild and dry place to ensure the safety of the mobile phone power supply.
5. The charging treasure enters the charging protection state, resulting in no charging. You can plug the charging bank into the USB output of the computer and charge it for 2 hours to release the charging protection state, and then it can be used normally.
