Why can't the power bank be charged when it is fully charged? What should I do if the power bank cannot be charged?

Power banks are a common charging tool in life, but many people encounter the situation that they can't charge suddenly when using power banks. So why can't the power bank charge a full charge? What should I do if the power bank can't charge? The following editor will explain them one by one, hoping to help everyone.

Why can't the power bank be fully charged?

If the power indicator light is on during charging, it is mostly due to a fault in the power bank's control circuit. If the signal indicator light flashes but the power cannot be charged, it is mostly a battery problem. If the power bank has not been used for a long time (number of times), you can try replacing the control circuit of a used power bank.

What to do if the power bank cannot charge

1. Check whether the charging data cable and plug are original. Although most power banks now use Android data cables, it cannot be completely ruled out that some power banks are more sensitive to cables. Try to use original ones.

2. Check the input voltage and current of the power bank, and try to ensure that the voltage and current of the charging cable are within the required range of the power bank. If it is too low, it may not be charged, and if it is too high, it may cause great damage to the power bank, and there is a very small probability that it will explode! This problem can be solved by replacing the original charging cable. If there is no original cable, be sure to check the input voltage and current.

3. Some power banks have a charging protection function. When the voltage is too high or the battery continues to be charged for a long time after being fully charged, the power bank may enter the charging protection state. At this time, connect the charging data cable to the computer USB port for charging. The charging protection state will be released after about 2 to 3 hours, and then you can charge it.

4. Some power banks cannot be charged after they have been completely exhausted if they have not been used for a long time. At this time, you can also use the charging cable to connect to the computer USB port. After charging for 2 to 3 hours, you can slowly charge it.

5. If the fourth point is triggered actively, manually drain the power bank completely and then connect it to the computer USB port to charge.

If the above methods cannot fix the power bank problem, the internal parts of the power bank may be damaged. Just replace it.

Is it bad for your phone to charge with a power bank?

Nowadays, mobile phones have excellent charging protection measures. For example, if you plug in the charger for a night, when your mobile phone battery is full, it will not charge your mobile phone battery. Because the protection circuit of the mobile phone is very good, there is no need to worry about the problem of charging with a power bank.

If you use a power bank to charge, it is very likely that the current is slower, so the charging will be slower. This is acceptable, after all, power banks are suitable for temporary emergency situations.
