To reset power bank issues like a device that won't charge your phone, a power bank that won't turn on, or one with lights stuck on, you typically reboot its internal controller with a soft reset or a pinhole reset button. A reset power bank procedure clears minor software glitches and restores normal operation without affecting stored energy.
When to reset power bank
You should consider a reset power bank routine if you notice specific symptoms that indicate a software-level problem rather than a hardware failure. These symptoms include the power bank not turning on when you press the power button, not charging devices even when connected properly, or being completely unresponsive to any input. Another clear sign is when the LED indicator lights stay stuck on or blink in an unusual pattern, which often means the internal controller is frozen. If the power bank overheats during normal use or drains its battery rapidly without powering anything, a reset can also help clear the glitch causing that behavior.
Before you reset your power bank
Take a few simple precautions before starting any reset procedure. Disconnect all cables and devices from the power bank, including the charging cable and any phones or tablets attached to its output ports. Ensure the power bank has some charge left, if it is completely drained, plug it into a wall charger for a few minutes first. If the unit feels hot to the touch, let it cool to room temperature before resetting, as heat can interfere with the internal electronics and make the reset less effective.
Method 1: soft reset with the power button
The most common reset power bank method works on nearly every model that has a physical power button. This soft reset reboots the internal controller without erasing any settings or requiring tools.
- Disconnect all cables and devices from the power bank.
- Locate the power button, usually on the side or top edge of the unit.
- Press and hold the power button for 10-20 seconds continuously.
- Release the button and wait a few seconds.
- Press the power button once normally to see if the power bank turns on.
If the power bank responds by showing its LED indicators or powering up, the soft reset worked. If nothing happens, try the pinhole reset method below.
Method 2: pinhole reset button
Many power banks include a dedicated reset button hidden inside a small pinhole, usually located on the side or back near the charging ports. This reset power bank method is designed for situations where the power button alone cannot clear a stubborn glitch.
- Inspect the exterior of the power bank for a tiny circular hole, often labeled "RESET" or marked with a small icon.
- Straighten a paperclip or use a SIM ejector tool.
- Insert the pointed end gently into the pinhole until it touches the button inside.
- Press and hold the reset button for a few seconds (typically 3-5 seconds).
- Remove the tool and wait a moment for the power bank to reboot.
After releasing the pinhole button, the power bank should restart on its own or respond to a normal press of the power button. If the pinhole is not present, your model likely only supports the soft reset method.
Method 3: battery calibration
When the battery percentage display is inaccurate, for example, showing 50% but dying moments later, a reset power bank routine alone won't fix the meter. Calibration resets the battery gauge so the display reflects the actual charge level.
- Use the power bank normally until it completely discharges and shuts off on its own.
- Leave the power bank off for at least a few hours to ensure the battery is fully drained.
- Connect the power bank to a wall charger using the original cable.
- Charge it uninterrupted to 100% without plugging any devices into it.
- Once fully charged, unplug it and use it normally.
This full discharge and recharge cycle recalibrates the internal battery management system. Repeat the process once more if the percentage display still seems off after the first cycle.
What a reset won't fix
A reset power bank procedure only addresses software glitches in the internal controller. It will not repair physical damage to the USB ports, such as bent pins or loose connections, which require hardware replacement. Faulty cables, whether frayed, damaged, or incompatible, will continue to fail even after a successful reset, so always test with a known-good cable. A chemically degraded battery that no longer holds a charge due to age or excessive heat cycles cannot be revived by any reset method; the only solution is replacing the power bank or its battery if the model allows it. If your power bank still misbehaves after trying all three reset methods, the issue is almost certainly hardware-related, and further troubleshooting will not help.
