Usually, the power bank’s LED will not turn on when it runs into charging issues. In some cases, you will see a charging indication, but the charge level will not increase.
Anything from a broken power cable to a damaged battery could stop the power bank from working. It could also be that the voltage from the power source is not enough to charge the device.
Besides this, extreme temperature also stops the power bank from charging. Its internal circuitry is designed such that the Lithium-ion battery stops charging once it reaches extreme temperatures, preventing the device from permanent damage. So you may also ensure that the power bank is not running too hot before getting into the fixes mentioned below.
Check the Power Cable, Port and Adapter
you may first start by ensuring that the power cable and adapter are functional. This may include broken/exposed wires, a bent power port, or even a swollen battery. If the cable or the adapter has visible damage to it, try using a different one.
However, if the power bank itself is damaged or swollen, there is a chance that the battery in your power bank is permanently damaged. If you are still under the warranty, you need to contact your manufacturer.
If the power bank and its charger do not have any visible damage, you may try using the power adapter on another device. The power bank usually charges with a micro-USB or USB Type-C port. So, you can try using the power bank’s power adapter and cable to charge another device that has a micro-USB or USB Type-C charging port.
If it charges another device, the issue is likely with the power bank itself. Furthermore, to charge the power bank,its charger should supply the correct amount of voltage and current. Your power bank will have a separate sticker that shows the amount of voltage required to charge it.
If the charger does not meet the voltage/current requirement, you may face issues when charging the power bank. In such cases, you may try charging the power bank using a different charger that meets the voltage/current requirement.
After a certain time of usage,dust will settle in the input portson any device. The dust particles can cause an obstruction, which may stop the input port from performing its task. In the case of power banks, dust particles on the power port may stop the device from charging. So, you should clean the ports to ensure that there are no dust particles on the charging ports (both input and output).
Reboot the Power Bank
Another reason the power bank fails to charge could be due to the residual charge stored in the capacitors inside the power bank. In such cases, you may try force-rebooting your power bank.
The process of rebooting the power bank can be different. For some power banks, you need tohold the power button for a few seconds to reboot. However, the process can be a little trickier for others and some power banks may not provide a power button at all.
To ensure that you follow the right steps, you may refer to the power banks user manual to reboot. If the user manual does not have the steps to reboot the power bank, it may not support a reboot.
Use Wall Outlet to Charge
