Unable to charge reasons:
1, there may be a problem with the quality of the adapter, any goods will have defective products. So in this case, please change the new line with the merchant in time.
2, it is possible that the USB contact of the mobile power supply is not very good. The mobile power supply has not been plugged in many times, and the interface part will always have some wear, which requires a new USB charging cable.
3, it is possible that the voltage of the mobile power supply is too low. The normal charging voltage of the mobile power supply is 5V, and the voltage of the mobile power supply will continue to decrease after the power consumption, generally when it is 4.3V, it can not be charged, because the battery voltage of the mobile phone will be increased to 4.2V when charging, so it must be higher than this voltage to charge.
1. It may be that the charging bank data cable or power adapter is damaged, resulting in failure to charge, replace the data cable or power adapter and charge again; 2. The charging interface or power switch of the charging bank may be faulty, and the parts need to be repaired and replaced; 3, may be the charging treasure battery aging, need to repair and replace the battery (if the charging treasure has been insured, it is recommended to directly replace the new charging treasure).
Reason: Charging cable problem Data cable contact is poor, it is recommended to use a new wire or use the original data cable. When the charging treasure is sold, it is generally equipped with a charging cable. When the charging treasure is not charged, first check whether the charging cable is broken, and you can use the data cable of the mobile phone to charge the charging treasure
