Why Power Bank Stops Charging After a While? Fix Like a Pro

Power banks have become an indispensable part of our lives, ensuring our devices stay powered up on the go. However, it can be quite frustrating when your power bank stops charging as expected.

In this article, we will delve into the reasons behind this issue and explore how you can prevent it. Let’s get started.

Understanding Power Banks

Power banks, also known as portable chargers, are external battery packs designed to charge your electronic devices when you can’t access a traditional power source. They come in various sizes, shapes, and capacities, making them convenient for various situations, from traveling to emergencies.

Why Power Banks Stop Charging

Learn the common reasons behind power bank issues and how to troubleshoot them effectively.


One common reason for power banks to stop charging is overheating. When a power bank gets too hot, its internal components may become damaged, leading to charging issues. To prevent overheating, avoid leaving your power bank exposed to direct sunlight and store it in a cool place.

Battery Degradation

Like all batteries, power bank batteries degrade over time. This degradation can result in reduced charging capacity and slower charging speeds. To prolong the lifespan of your power bank, avoid overcharging and discharging it completely.

Incompatible Cables

Using low-quality or incompatible charging cables can lead to charging problems. Always use high-quality cables that are designed for your specific device to ensure a stable charging connection.

Firmware Issues

Some power banks may experience charging problems due to firmware issues. Updating your power bank’s firmware can sometimes resolve these issues, so it’s essential to check for firmware updates regularly.

Signs that Your Power Bank is Failing

To identify if your power bank is failing, watch out for signs such as significantly slower charging times, reduced capacity, or the power bank getting abnormally hot during charging. These signs can indicate underlying issues that need to be addressed.

Preventive Measures

Ensure your power bank’s longevity by adopting these simple yet effective practices for hassle-free charging.

Proper Storage

Keep your power bank somewhere dry and cool. Avoid exposing it to extreme temperatures, as this can lead to battery degradation and overheating.

Charging Habits

Troubleshooting Tips

Quick fixes and solutions to keep your power bank charging smoothly when issues arise.

Cooling Down

If your power bank gets too hot, stop using it immediately and let it cool down. By doing this, harm to the internal parts may be avoided.

Checking Cables

Ensure that you are using high-quality and compatible charging cables. Sometimes, the issue might be with the cable rather than the power bank itself.

Firmware Updates

Check for firmware updates for your power bank. Manufacturers often release updates to address known issues and improve performance.

When to Replace Your Power Bank

If your power bank continues to exhibit issues despite troubleshooting, it may be time to replace it. Batteries have a limited lifespan, and if yours has reached the end of its useful life, a replacement is the best course of action.
