Basic Troubleshooting Steps

First, reset and restart your power bank. Do this by uncoupling and recoupling the battery pack. This can help reset the system and resolve many technical issues. If this basic step doesn’t work, then there are several other things that you can try.

1) Use different cables: Try using a different charging cable or wall adapter to charge your power bank and check whether it works properly with the new accessory. Many times, the issue may be due to faulty cables.

2) Check charging port: If your power bank’s charging ports are not functioning correctly, you may want to check them for any signs of damage such as bends or breaks which could be causing interference with the connection.

3) Check battery health: Excellent battery health is important for a smooth functioning cordless power bank. To ensure that yours is well maintained, use an appropriate charger and take precautions when discharging a full or low-charge unit. Also, take care when handling product with removable batteries as they are extremely fragile components that could easily get damaged if handled improperly.

4) Test different outlets: It’s always a good idea to test your cordless power bank under different kinds of outlets such as car chargers, wall chargers and USB ports in order to get a better idea of what’s causing the issue with it not charging properly or completely draining out before time.

5) Update Software/firmware: Power banks may have updates released periodically so make sure you have all necessary patches installed on yours for best results with connectivity/charging/discharging operations kept up-to-date along with software updates in order to stay on top of your device’s performance level.

Check the Connections and Cables

Before beginning any troubleshooting on your cordless power bank, the first step should always be to check the connections and cables. Verify that the charging cable you are using is compatible with your device and make sure it’s firmly connected at both ends. You may also want to try a different charging cable and/or wall adapter to ensure that either or both are not faulty.

Make sure no dirt or dust has built up on the charging contacts of either device. If necessary, use an electronics-safe brush or compressed air to remove any potential obstructions and then retry charging your power bank.

Inspect the Battery Level and Charging Status

The power bank has two parts — the battery pack and the charging cable. To inspect the battery level and charging status of your cordless portable power bank, you will need to first check whether the power bank is correctly connected to your device using a USB cord or wall adapter.

To check the battery level and charging status of your power bank, click or press on the power button. If there is still a full charge remaining in the device, you should observe at least four out of five LED lights illuminating on its front side when this button is clicked. The LED lights indicate how much charge remains within the device; each LED denotes a 25 per cent increment in battery capacity. If fewer than four LED lights are observed when pressing on this button, it might be time to re-charge your cordless portable power bank.

You can also visit your Power Bank settings through your device settings menu (i.e Apple/Android) for more detailed information about its current charge level and charging status if required.

Restart or Reset the Power Bank

If restarting your device does not solve the issue, you may need to reset or factory reset the power bank. Resetting a power bank turns it off and on again as part of its regular boot-up routine. This can sometimes clear any glitches or problems that have developed with its programming or charging circuits.

To reset your power bank, simply press and hold the “Power” button for 5-10 seconds until the LED lights turn off. Once these lights turn off, release the button, then press it once more to restart your device. This procedure will usually solve most operational issues with your cordless power bank quickly and easily.

Advanced Troubleshooting Techniques

If the above trouble-shooting techniques have not resolved your issue, we recommend trying some of the more advanced techniques outlined below. You may also want to contact a qualified technician if your attempts fail or prove too daunting.

Reset your power bank: A soft reset may resolve the issue. To do this, deplete the battery completely and recharge it fully. This will unplug any connections that weren’t able to shut down properly during its last use, resulting in improved performance.

Check for potential damage: Inspect all visible and connected parts for evidence of damage that may account for any malfunction or failure issues you’re experiencing with your power bank. If there are signs of physical damage such as broken buttons, cracked ports, fraying wires, etc., then consider seeking professional help and/or replacing it with a new model if warranted.

Update driver software: Make sure you’re running the latest driver version for your device as older versions can cause problems. You can usually find recommended updates by searching by device name and model number online, but always double-check before downloading anything from an unfamiliar source!

Diagnosing Faulty Components

Diagnosing Faulty Components

Before you start to troubleshoot and diagnose your cordless power bank, it’s important to know the basics of how these components work. Knowing this will help you to easily determine if the power supply is faulty or if any other elements are the cause of your issues.

The power supply is usually comprised of three main components — a power brick, cord and voltage converter — all working in combination to deliver electricity to your device when plugged in. The brick works as a step-down converter, reducing current from a higher level, to make it compatible with lower consumer electrical outlets (120V standard in North America). The lead itself contains two wires; one that carries power from the wall socket, and another that carries electricity back out.

The converter is responsible for regulating volts delivered from the wall socket and converting them into the optimal voltage needed by the device being charged. If any one of these components is defective or prone to malfunctioning, this can be an indicative sign that your battery won’t adequately charge. If these factors are not properly maintained or replace when necessary, your battery could undercharge and may become damaged over time due to insufficient charging cycles.

Checking for Physical Damage

While cordless power banks are engineered to be resilient and long-lasting, physical damage is a possibility. Given the power banks oftentimes have Li-ion cells, any physical damage, such as denting or puncturing, can cause irreparable injury and result in no output or charging.

Check your power bank over for any signs of obvious visible signs of physical damage that could lead to malfunction. If you find any notable sign of wear or tear, discontinue using the device until it can be inspected and provided with an accurate diagnosis.

Testing the Voltage and Amperage

Testing the voltage and amperage of your cordless power bank can help you determine which components are causing issues or not working correctly. You’ll need a multimeter, set to AC volts and AMPs, to measure the voltage and amperage of your power bank.

To begin the voltage and amperage test, connect one probes of the multimeter to one end of the battery terminals on the power bank; this should let you know whether or not it’s being charged properly. For models with replaceable batteries, make sure that they are connected properly before testing. If there is no charge when monitoring with a multimeter, then it’s likely that your charger is not giving enough voltage to charge or it’s simply not charging at all.

The next step is to measure the amperage being sent from the charger. To do this, connect one probe each to either side of the DC port on your charger itself, using an appropriate size adapter as needed. The results should indicate if any current is being passed through wires connecting your power bank battery and DC jack — if current doesn’t pass through either way then there may be an issue with either the wiring or one of its components. A practical level should be within 5% – 20% of what was listed on its documentation when you purchased it in order for it function properly; any discrepancy here may hint at a faulty part needing replacement or repair.


We have now come to the end of this guide. We have discussed all types of troubleshooting issues with your cordless power banks like not charging properly, not turning on at all, incorrect battery levels and problems connecting your device. We hope you are now able to detect any issues with your device and resolve them in an efficient manner.

Remember, if you are unable to solve the issue yourself or if the problem is too complicated for an untrained individual, you should seek professional help from a certified technician. If the problem is related to general wear and tear of the powerbank due to regular use, then it is important that you get it serviced from a trusted service centre as soon as possible.
