If you currently have your power bank plugged in but no red light is visible, you could be having some of the issues detailed in this guide.

How Do I Know If My Power Bank Is Not Charging?

Most power banks will have a LED lighting system that indicates the different levels of charging. Consult the manual for the specifics of your device and then check for the light indicator that signifies charging. If the proper lighting notification is not displayed, then it will be safe to assume that your power bank is not charging properly.

Why Isn’t My Power Bank Charging?

1. Power Banks Data Port Is Dirt Or Damaged

Your power bank has ports that help to facilitate the charge between your device and a power outlet. This port is in addition to the one that transfers charge from your power bank to your phone, tablet, or laptop.

Over time, these ports can accumulate dirt or grime, which can keep them from functioning correctly. There is also the possibility that damage could have been incurred from improperly removing the charging cable, or from general wear and tear.

You will find that all charging ports across all your devices are prone to wear out over time, leading to connectivity problems when trying to charge your devices. This is sometimes the case with power banks.

Since the power bank is used so much, it is subject to being plugged and unplugged much more frequently than other devices. This can cause the ports on your device to wear much quicker than you would normally expect.

One way to avoid this is to keep your charging ports clean, while also trying to remove the charger carefully to avoid any damage. While no charging port lasts forever, you might find that if you avoid plugging and unplugging your device unnecessarily, it will last longer.

2. Cable Problem

By the same token, your charging cable could be the reason that your power bank is not able to draw any power. Charging cables are one of the most heavily used utilities in the whole world. As with any item that is frequently used, it is subject to significant wear and tears over time.

Generally, a charging cable is very durable, often lasting a while before needing to be replaced. A charging cable is much easier to replace than a faulty charging port, so cable issues are the preferable issue to encounter.

As a charging port, a cable can only be used so many times before the connector tip is worn down and will no longer efficiently charge your device. The lifespan of a charger will depend on the type and how it is treated when in use.

A charging cable is prone to damage, so it is important to be careful when removing and connecting to a device. Since your charger is likely to see frequent use, you can expect to have to replace it at least once in your device’s lifetime.

To lower your chances of having charger issues, consider annual replacements to avoid any loss of functionality when you need it. Being careful when handling your charging during plugging and unplugging can also help further the longevity of your charging cable.

3. Software Issues

More modern and technologically advanced power banks might use additional software to help give the user access to additional features. If your power bank utilizes Wi-fi or has some sort of feature that supports something other than basic charging, then you will most likely have to keep up with regular software updates like you would any device.

Software issues are a common problem with any modern technology, including power banks. Most devices depend on periodic updates to their software to patch out bugs and glitches and optimize features for the user.

If you have let your device fall behind on updates, this can cause connectivity issues when trying to charge, among other problems that will cause your power bank not to function correctly.

The best way to avoid this is to determine whether or not your device supports updates. If you find that it does, be sure to check back now and then and see if you have one available to install.

4. Battery Problems

All batteries have a finite lifespan. Your power bank is essentially just a portable rechargeable battery. Once the battery starts to near the end of its lifespan, you will start to encounter more problems till it eventually stops working entirely.

The lifespan of your power bank battery will depend largely on the brand and how often you used it. The lifespan of a power bank battery is typically quite long, though excessive use can lead to the battery’s lifespan being depleted faster.

Damage incurred to your power bank can also affect the battery. If your power bank has gotten wet or dropped, it could have damaged the battery to the point where it can no longer efficiently be charged. If you start having battery issues after dropping your device or getting it wet, you have most likely damaged the battery.

There is no way to fully avoid your power bank battery eventually breaking down, but with proper care, you can ensure that your device has a long life. Preventative measures include proper storage and handling and charging habits.

5. Socket Issue

The problem with your power bank not charging could be stemming from a faulty outlet socket in your home that you are currently plugged into. Your electrical outlets can become faulty due to wiring issues or issues with the connection ports.

You can test your power bank by using another outlet and seeing if it can charge properly. If it does, then you were likely plugged into a faulty outlet. Faulty outlets can be dangerous and should be addressed as soon as possible.

Only a licensed electrician can fix a faulty outlet in your home. It is not recommended that you attempt electrical repairs yourself. Doing so could be dangerous. You should also avoid plugging into faulty outlets, else your risk damaging your devices.

6. You Are Using An Extension Cord

Extension cords are a great way to temporarily stretch the range of a power outlet. They are typically not recommended for long-term use. The use of an extension cord with your power bank should not cause any problem, but long-term use could cause issues.

Extension cords are prone to damage, both external and internal. As most extension cords that you would typically plug your power bank into are relatively cheap, they can often incur damage that causes issues when transferring power.

If you are using an extension cord with your power bank, consider plugging directly into the power outlet if possible. You will likely find that your extension cord is simply defective and needs to be replaced.

Extension cords, like charging cables, are prone to wear after long-term use which could cause them to not function properly. Consider using only direct links to your power outlets for the most efficient charging.

7. You Are Not Charging It Long Enough

For your power bank to charge your devices optimally, it is recommended that you allow it to charge to full power before trying to use it. This will also lower the number of times that you must charge it since it will have full power available after every charge.

If you unplug your power bank before it has time to charge properly, it might not have enough battery power stored up to properly charge your device. The minimum that you should allow your power bank battery to charge before attempting to charge a device is halfway. Anything below that and your risk your device not being charged properly.

Any device that contains an internal battery that holds a charge will last longer if you let them charge to full and die before charging. This is sometimes not ideal, but the idea is that the less frequently you have to plug your device in, the longer the internal battery and charging ports will remain functional.

8. You Are Charging It With A Laptop

Most power banks can charge via USB. This makes charging simple and easy, with most providing an adapter that you can use when utilizing USB charging. This adapter, usually a small brick adapter, helps to facilitate the proper charge from a wall outlet to your power bank.

If you try to hook your power bank up into a laptop, you will likely find that it is unable to efficiently draw power. While your laptop might be able to deliver some charge to your device, it is likely not powerful enough to charge your power bank optimally.

If you get your power bank to register a charge from your laptop at all, it will likely take several times longer than normal to fully charge. Any power that your laptop is drawing will first be utilized by the laptop itself. The power is then passed to your power bank, where it will not be as effective as if the power bank were plugged in independently.

The best way to utilize USB charging on your power bank is to use the power adapter that is appropriate for your model.

9. You Are Trying To Charge A Device At The Same Time

Typically, a power bank will not support charging at the same time as a connected device. The power bank needs time to store the power up to efficiently charge any connected devices. If you have a device connected while you are trying to charge your power bank, you will find that neither will charge efficiently.

You could risk damaging your devices when using them in this manner. The safest way to charge your devices is to wait for the power bank to accumulate enough charge to transfer the power properly.

Consider just charging one of the other if you are in a position where you have to choose. Often in this type of situation, you could just simply charge the device you were trying to charge with the power bank.
