To reset a power bank, remove all cables, press and hold the power button for 10 to 15 seconds, leave it for one or two minutes, then charge it again before testing it with your phone. This simple reset can fix small charging errors, frozen LED lights, and power output issues.
If your power bank is still not charging after a reset, the problem may be with the cable, charging adapter, USB port, battery health, or internal circuit. In some cases, replacing an old power bank is safer than trying to keep using it.

Why Does a Power Bank Need Resetting?
A power bank is not just a battery. It also has a small control system inside. This system manages charging, output, LED lights, battery protection, and power flow.
Sometimes, this system can freeze or act incorrectly. A reset gives the power bank a fresh start.
You may need to reset your power bank if:
- It is not charging your phone
- It is not charging itself
- The LED lights keep flashing
- It turns on but gives no power
- It switches off too quickly
- The battery level looks wrong
- Wireless charging is not starting
- The USB-C port is not responding
For UK users who carry a power bank for work, travel, university, trains, shopping, or outdoor plans, this issue can be annoying. A quick reset may save you from replacing the device too early.
How to Reset a Power Bank Step by Step?
Step 1: Disconnect Everything
Remove every cable and device from the power bank. Do not keep your phone, charging cable, wall plug, or wireless device connected.
This helps the power bank stop all current activity before the reset.
Step 2: Press the Power Button Once
Press the power button once to check if the LED lights turn on. If the lights appear, wait a few seconds.
If the lights do not appear, move to the next step.
Step 3: Hold the Power Button
Press and hold the power button for 10 to 15 seconds.
Some power banks will flash their LED lights. Some will turn off. Some will show no clear sign. That is normal because every model works differently.
Step 4: Leave It for a Short Time
After holding the button, place the power bank on a dry, flat surface. Leave it unused for one or two minutes.
Do not plug in your phone right away.
Step 5: Charge the Power Bank Again
Connect the power bank to a wall charger. Use a good USB-C cable if your model supports USB-C charging.
Let it charge for at least 30 minutes before testing it again. If the battery is fully drained, it may take a little longer before the lights appear.If you are unsure about charging methods, read our guide on how to charge a power bank correctly.
Step 6: Test It With Your Phone
Now connect your phone. Check if charging starts. If your power bank is magnetic, align it properly with the back of your phone.
If charging starts, the reset worked.
How to Reset a Magnetic or Wireless Power Bank?
A magnetic or wireless power bank may stop charging if the phone is not aligned properly, the case is too thick, the battery is low, or the power system is frozen.
To reset it:
- Remove the power bank from your phone
- Take off any thick case, cards, metal rings, or magnetic accessories
- Press and hold the power button for 10 to 15 seconds
- Leave it unused for one or two minutes
- Charge the power bank for 30 minutes
- Place your phone back in the centre of the charging area
- Make sure the magnets line up correctly
- Wait a few seconds for charging to begin
Wireless charging can take a moment to start, so do not remove the phone too quickly.
If your magnetic power bank keeps disconnecting or charging stops again and again, a newer Magnetic Power Bank with a stand can be a better choice for desk use, video calls, travel, and bedside charging.
What If the Reset Does Not Work?
If your power bank still does not work, the reset may not be the real fix. Check these things before you give up.
- Check the Charging Cable: A damaged cable can stop the power bank from charging or giving power. Try another cable and test again.
- Check the Wall Charger: Some low-power plugs charge very slowly. Use a stable wall charger that can give enough power to the power bank.
- Try Another Phone: Connect the power bank to another phone. If it charges the second phone, your first phone or cable may be the issue.
- Check the USB Port: Dust inside the port can block charging. Use a dry soft brush to clean it gently. Do not use water.
- Let It Charge Longer: If the power bank battery is fully empty, it may need 30 to 60 minutes before it shows any sign of life.
Signs Your Power Bank May Need Replacing
A reset can fix a small system fault, but it cannot repair an old or damaged battery.
Your power bank may need replacing if:
- It drains very quickly.
- It takes too long to charge.
- It charges your phone only for a few minutes.
- It gets too hot
- The case looks swollen.
- The USB port feels loose.
- The lights keep acting strangely.
- It shuts down again after every reset.
If the power bank is swollen, cracked, leaking, or giving a burning smell, stop using it. Do not charge it again.
This is a strong place to guide readers toward safer new options like the 10000 mAh Magnetic Power Bank or the Magnetic Power Bank with Stand. Most power banks gradually lose battery capacity over time. You can read more about how long a power bank lasts and what affects its lifespan.
Can Resetting a Power Bank Damage It?
No, a normal reset should not damage your power bank. Holding the button and removing cables is safe when done correctly.
Avoid unsafe actions such as:
- Opening the power bank
- Pushing metal objects into the port
- Using broken cables
- Charging near water
- Leaving it in a strong heat
- Using a swollen battery pack
Power banks use lithium battery cells, so safe handling matters.
Why Is My Power Bank Flashing But Not Charging?
Flashing lights can mean different things. In many cases, the battery is low, or the power bank is trying to charge.
It may also mean:
- The cable is loose
- The wall plug is weak
- The battery is fully drained
- The safety system has paused charging
- The power bank has an internal fault
Reset it first, then try another cable and wall charger.
