Low Battery Level

One of the most common reasons a power bank won’t charge is its low battery level. When the power bank’s battery level is too low, it cannot charge your devices.

To fix this, plug the power bank into a power source and let it charge for a few hours until the battery is full. Some power banks have LED lights indicating when the battery is full, so watch for those.

Faulty Charging Cable

A faulty charging cable is another common cause of power banks not charging. If the charging cable is damaged, broken, or worn out, it cannot charge your devices.

First, check the charging cable for any visible damage, such as frayed wires or bent pins. If there’s damage, replace the cable with a new one.

If there’s no visible damage, try using a different cable to charge your power bank. If the power bank charges, the original cable was the issue, and you should replace it.

Dirty or Corroded Charging Port

Dirt, debris, or corrosion can accumulate on the charging port of the power bank over time, causing it to block the connection and prevent it from charging your device.

To fix this, use a clean, dry cloth to wipe the charging port of your power bank. If the port is severely damaged or corroded, take it to a professional to repair or replace the power bank.

Device Compatibility

Some power banks are only compatible with specific devices; if you try to charge an incompatible device, it won’t charge.

Check the compatibility of your device with the power bank. If your device isn’t compatible, you may need to buy a power bank that is compatible with your device.

Insufficient Power Source

If the power source you’re using to charge your power bank is weak or insufficient, the power bank won’t charge.

Try using a different power source with sufficient power output to charge the power bank. Also, check if the power source is working correctly.

Overheating

Overheating can cause the power bank to stop charging. This happens when the power bank is exposed to high temperatures or charging too many devices simultaneously.

Let the power bank cool down for a few minutes before using it again. Avoid charging too many devices simultaneously, and keep the power bank in a cool, well-ventilated place.

Damaged Battery

If your power bank is old or has been used extensively, the battery may be damaged, which could cause it to stop charging.

You may need to replace the power bank entirely if the battery is damaged. However, before doing that, try charging the power bank with a different solution, such as using a different charging cable or power source, to see if that fixes the problem.

If the problem persists, it’s time to replace the power bank.

Internal Circuitry Issues

In rare cases, internal circuitry issues can cause power banks to stop charging. This can happen if there’s damage to the internal components, such as the charging circuitry or the battery itself.

If you suspect an issue with your power bank’s internal circuitry, take it to a professional technician or the manufacturer’s service center for repairs. Attempting to repair the circuitry yourself can be dangerous and may cause further damage to the power bank.

Frequently Asked Questions (FAQs)

How do you force charge a power bank?

First, locate the USB cord and wall adapter that came with your power bank to force-charge a power bank. Connect the larger end of the USB cord to the wall adapter, then plug the smaller end into your power bank. Make sure to use a wall outlet with a stable power supply. Leave the power bank to charge until it reaches full capacity.

What is the lifespan of power banks?

Battery power banks have a limited lifespan and typically last between 1.5 and 3.5 years, equivalent to 600 to 1,000 full-cycle charges and depletions. However, the lifespan of a power bank can be prolonged by taking proper care of it, such as avoiding exposure to high temperatures and regularly charging it to maintain a healthy battery.

Do power banks harm batteries?

Using power banks excessively can cause damage to your phone’s battery over time, leading to a decreased battery lifespan and potential loss of charge. To prevent this, using power banks only when necessary is recommended to avoid overcharging your phone with them. Instead, maintain your phone’s battery level between 20-80% for optimal battery health.

Conclusion

Low battery level is a common cause of power banks not charging devices. To solve this issue, simply charge the power bank until the battery is full by plugging it into a power source. Keep an eye out for LED indicators that signal a full battery.
A faulty charging cable can prevent power banks from charging devices. Check for visible damage and replace the cable if necessary. If there’s no visible damage, use a different cable to charge the power bank. If the power bank charges, the original cable is faulty and should be replaced.
If dirt, debris, or corrosion accumulates on the charging port of your power bank, it may block the connection and prevent your device from charging. Wipe the charging port with a clean, dry cloth to fix this. If the port is badly damaged or corroded, it’s recommended that professional help be sought to repair or replace the power bank.
