Picture a situation where you’re relying on your power bank to keep your smartphone alive during a busy day, only for it to mysteriously switch off, or when you’re eager to recharge it, and it decides to take an unplanned rest. What a nightmare, isn’t it?
If you’ve encountered this exasperating moment, you’re not alone. That’s why we are here to help you out. Together today, we are going to explore two key scenarios – power bank shutdowns while charging other devices and during their own recharging process.
We are also going to provide practical solutions to ensure that your power bank remains a dependable ally in your pursuit of uninterrupted connectivity.
Without further ado, let’s begin!
Why Does Power Bank Turn Off While It Charges Another Device?
Okay so why does your power bank keep turning off inexplicably during the crucial task of charging another device? Well, let’s discuss the possible causes and their solutions.
Problem 01: Low-Quality Cables and Connectors
At the heart of the problem lies the often underestimated charging cables and connectors. These seemingly innocuous components play a significant role in ensuring a smooth flow of power from your power bank to your device.
However, when these accessories are of poor quality, they can mess up and ruin your charging experience. Low-quality cables and connectors are well-known for causing voltage drops and inconsistent connectivity, leading to the power bank disconnecting, seemingly of its own accord.
Problem 02: Inadequate Power Bank Capacity
Another common issue is an inadequate power bank capacity relative to the device being charged. Power banks come in various capacities, typically measured in milliampere-hours (mAh) or watt-hours (Wh). If your power bank has a lower capacity than the device you’re trying to charge, it may not provide sufficient power, causing it to shut down prematurely.
Problem 03: Faulty ICU
All power banks have an internal control unit (ICU). This is what regulates the current levels in the device. Once it identifies a USB connection, its circuit begins charging the external device.
However, if this ICU is defective and worn out, it can no longer control the current (I) nor detect any USB connection. In such a case, the power bank automatically turns off as it assumes there’s no device being charged.
Problem 04: Battery Dead
It doesn’t always have to be so complicated! Sometimes, your power bank may turn off, not because of any damaged internal components, but simply because it ran out of battery power.
Therefore, because it can no longer charge another device, it decided to turn off itself and take a nap.
How to Resolve These Problems?
Once you’ve identified what exactly is the problem, go ahead and troubleshoot your power bank with the help of these suggestions below:
Solution 01: Investing in High-Quality Accessories
To tackle this issue, invest in high-quality charging cables and connectors from reputable brands. Seek out accessories with durable construction and efficient power transfer capabilities.
This way you can significantly reduce the chances of power interruptions caused by poor connectivity.
Additionally, it’s wise to regularly clean the charging ports of both your power bank and your device to remove dust and debris, which can further hinder a secure connection, ensuring a consistently reliable charging experience.
Solution 02: Match Power Bank Capacity to Device Needs
Check your device’s battery capacity (often listed in mAh or Wh) and compare it to your power bank’s capacity.
If your power bank has a lower capacity, consider upgrading to a higher-capacity model. This ensures that the power bank can deliver the necessary power to charge your device fully without shutting down mid-charge, providing a more reliable charging experience.
Solution 03: Repair ICU
Well, there’s nothing much you can do by yourself if the ICU component is damaged. You’ll have to call a professional technician to get it repaired or replaced with a new one. You may also want to contact the manufacturing company first to see if you can get free replacements under non-expired warranty.
Solution 04: Charge Battery
Before thinking anything too sophisticated, simply try charging your power bank for a couple of hours. Give it some rest and then try charging your devices again. Perhaps, the issue will be gone.
Why Does Power Bank Turn Off While It’s Being Charged?
Now let’s shift our focus to the annoying issue of power banks shutting down during their own recharging process. Crazy right?
So, let’s talk about the two main problems that may cause this and what you should do to resolve each.
Problem 01: Overheating
Power banks, like all electronic devices, are susceptible to overheating during the charging process. To safeguard against potential damage caused by excessive heat, power banks are equipped with safety mechanisms that can trigger an automatic shutdown.
Solution 01: Ensure Proper Ventilation
To tackle this problem effectively, it’s essential to ensure proper ventilation when charging your power bank. Avoid enclosing it in tight spaces or covering it with insulating materials like blankets. Instead, place your power bank in a well-ventilated area during charging. This allows heat to dissipate more effectively, reducing the risk of overheating and the subsequent shutdown. By adopting this practice, you can not only enhance the longevity of your power bank but also ensure a more reliable charging experience.
Problem 02: Incompatible Chargers
Using a charger with a higher wattage output than what your power bank is designed to handle can generate excess heat during the charging process. This can lead to overheating and, ultimately, a shutdown to prevent damage.
Solution 02: Match Charger Wattage to Power Bank Specifications
To overcome this issue, always match the wattage of the charger with your power bank’s specifications. If your power bank is designed to handle a certain wattage, use a charger that provides an equal or lower wattage output. This practice ensures that your power bank receives the appropriate amount of energy without overheating, preventing unexpected shutdowns and potential damage.
By addressing these common problems (such as low-quality cables, proper ventilation, and matching charger wattage etc.) and implementing these practical solutions suggested above, you can ensure that your power bank remains a steadfast companion in your quest for uninterrupted connectivity – whether you’re charging your devices or recharging the power bank itself.
Frequently Asked Questions
1. How do I stop my power bank from turning off?
Answer: Always use high-quality accessories. Invest in good cables and connectors. Always keep your charging ports clean by removing dust and debris regularly. It’s also important to match power bank capacity – ensure it meets or exceeds device needs. Avoid cramped spaces and insulating materials and always stick to recommended wattage or lower.
2. How do you keep a power bank awake?
Answer: Additionally, some power banks have features like LED indicators or shake-awake functions that can help keep them active. Ensuring that your power bank is periodically charged and discharged can also help maintain its readiness for use.
3. How long should a power bank last?
Answer: A well-maintained power bank can last for approximately 3-5 years or up to 500 charge cycles, but this can vary depending on usage patterns and quality.
4. Why does my power bank turn off after 30 seconds?
Answer: Your power bank may turn off after 30 seconds due to its built-in power-saving features. Many power banks are designed to conserve energy and automatically power down when they detect inactivity to save power for future use. You can typically reactivate them by pressing a power button, shaking them, or simply plugging in a device to charge.
