Hello, first of all, you first confirm that the mobile phone, charging bank is not out of power, is not completely out of power, especially the mobile phone in a cold environment without power is easy to enter a hibernation state, this time with a charging bank or computer terminal charging is more difficult to wake up, this time it is recommended to use direct charging.
The same goes for power banks. If you need to charge more than 50% of the electricity for a long time, it is not easy to run out of power and cannot be used.
The second is the problem of voltage or current, because some mobile phones are special, the voltage is different, so it can not be charged, the normal lithium battery is 3.7V voltage, such as the Apple mobile phone uses 5V voltage, if the charger does not do the boost, the general lithium battery is unable to charge the Apple mobile phone.
There is also the interface problem, because the charging bank in order to adapt to a variety of mobile phone applications, so are configured with common mobile phone interfaces.
If your phone interface and the charging bank interface do not work, you should change a data cable to try. We can rule that out with the naked eye, can't we? Have you successfully charged your iPhone with an Android port? Then there are the particularities of some mobile phones themselves.
They strictly control the charging voltage and current, resulting in some charging treasure can not be charged for it, try to change a charging treasure. Before choosing a charging bank, also know your mobile phone charging voltage and current, so as not to spend money and worry.
The main reasons are:
1, the power of the charging treasure is insufficient to automatically power off, you can charge the charging treasure for a period of time, and then charge the phone after the power is sufficient.
2. The connection between the charging bank and the mobile phone is faulty, resulting in automatic power failure. For example, the connection between the data cable and the charging bank, the data cable and the mobile phone is loose. If necessary, you can change a data cable to reconnect the charge.
3, the mobile phone system problem leads to automatic power off charging, you can restart the phone to try, or turn the phone off and try charging in the shutdown state.
4. It may also be caused by the hardware failure of the mobile phone or charging bank, such as the charging port failure of the mobile phone, the internal circuit failure, the mainboard chip and other parts failure, or the battery failure of the charging bank, the circuit board failure, etc., which needs to be repaired or replaced by the corresponding after-sales service.
