Power banks may be lifesavers, but they can also be a source of frustration when they malfunction. One of the most typical issues with portable chargers is that their lights may flicker in a certain pattern that is difficult to decipher at first.
The erroneous light blinking might also be caused by another problem, such as the battery bank not being able to recharge. In this post, we’ll look at some of the most prevalent reasons and treatments for this problem..
The LED indicator lights and their functions
The majority of power pack are equipped with four miniature LED power indicator lights that give information about the battery’s charging status.
The power bank’s LEDs are flickering as a source of illumination.
One of the LED lights on a power bank will often blink when you connect the power bank to a power outlet to recharge it, signalling that the power bank is accepting the charge. As shown in the illustration, each of the LED lights indicates the current state of the battery’s charge:
- The first light flashing indicates that it is between 0 and 25 percent charged.
- The second light flashing indicates that the battery is between 25 and 50 percent charged.
- The third light flashing indicates that it is between 50 and 75 percent charged.
- When the fourth light blinks, it indicates that the battery is between 75 and 100 percent charged.
- During the charging process, these lights are often on and off. They also flash if you click the power button to see how much power is left in the power bank, which is a function that practically all power banks offer as well. When the device’s four LED lights are illuminated continuously, it indicates that the unit has been completely charged.
When you connect your mobile phone to the power bank, on the other hand, the LED indicator will begin to blink, showing the following information:
- When all four lights are flashing, it implies the battery has between 75 and 100 percent of its charge left.
- Three flashing lights indicate that it has between 50 and 75 percent of its charge left.
- Two flashing lights indicate that it has between 25 percent and 50 percent of its charge left.
- When just one light blinks, it indicates that it has between 0 and 25 percent of its battery left.
If you want to avoid the power bank from totally depleting, you should unplug the mobile phone at this time, since doing so may cause harm to the battery, particularly if done frequently.
LED lights blinking but the power bank won’t charge
In rare circumstances, you may observe that the power bank is not charging, despite the fact that it is plugged in, and that the LED lights are flickering. This is normal.
In other circumstances, you may have to wait many hours or even a day before the power bank will charge, or it may only charge halfway or somewhere in between, despite the fact that the lights on the power bank indicate that it is completely charged. Something does not seem to be quite right.
Is this an indication that the power pack has fully failed, or is it something more minor? The reality of the case is that there is no clear yes or no response in this circumstance.
It is possible that this problem is caused by a variety of distinct conditions. Because of this, we’ve devised a self-diagnosis checklist that you may use to determine the source of your issue.
Possible causes and troubleshooting checklist
It is possible that the problem is a little flaw that can be quickly corrected, or that it is a significant problem that need expert repair services. It might be caused by one of the following issues:
1. Make sure that the power cable is fully inserted
It is possible that you simply did not properly put the power connector into the charging port, resulting in a poor connection between the two devices. Examine the plug to ensure that it fits tightly into the socket. In addition, make certain that the power connection on the power bank is completely put into its respective socket.
Take care to ensure that there isn’t any form of foreign matter in the charging port such as dust, sand, or dirt. Sometimes contaminants that get lodged in the socket might result in a poor connection. Just be cautious not to break one of the pins if you do it incorrectly.
2. Try using a different power cable
Alternatively, if the connections are secure but the battery bank is still not charging, it is likely that the power cord is defective. Some power cords might be of very poor quality, which has a direct impact on the charging pace of the device.
It is also possible that the cable does not support rapid charging technology, which is required by the power bank, and as a result, the power bank is not receiving enough charge. It is simple to resolve this problem by changing the power cord and attempting again.
3. Charge the power bank via a wall socket, not via a laptop USB
If possible, charge the power bank from a main electric power outlet rather than from a computer, since the output current from a computer’s usb connection is normally less than half an amp (0.5 A), which is insufficient to charge the power bank.
4. Try charging the power bank with a different adaptor
It is conceivable that the adapter you are using to charge your power bank has become broken or that the value it produces is so low that the power bank is unable to charge. Instead of using the same adapter, try using a new one. If this method succeeds, you may be assured that the charger is defective, and you should replace it immediately.
5. The power bank battery might have died
You may have an internal issue with your power pack if it does not seem to be charging properly, as no lights illuminate when attached to a power source and no charge appears to be occurring when your mobile phone is linked to it.
If the power bank has been subjected to a severe shock, such as a fall, or has been exposed to high temperatures for an extended period of time, it is possible that its internal circuits have failed.
If you have used your power bank on a regular basis, it is possible that the batteries have reached the end of their useful life. According on the manufacturer and model, power bank batteries have a life span ranging from 300 to 1000 cycles of use.
In all of these instances, the condition is significant, and the power bank should be fixed by a qualified technician.
