How to reboot Xiaomi Verbank correctly: all ways + problem solving

Xiaomi’s superbanks are some of the most popular external batteries on the market, thanks to their combination of price, capacity and reliability, but even with these devices, there are sometimes problems: indicators freeze, refuse to turn on or malfunction. USB-In most cases, a simple reboot helps, but not everyone knows how to do it correctly without risking damage to the device.

In this article, we will discuss all the working ways of rebooting for Mi Power Bank, Redmi Power Bank and other models of the brand, from the classic reset button to forced discharge. You will also learn what to do if the superbank does not react to the reboot and does not show signs of life (this happens when a deep discharge or a controller failure), instructions are suitable for devices of any capacity, from compact 5000 mAh to powerful 20,000 mAh+.

1.When do you need to reboot Xiaomi's overbank?

Not all malfunctions require resetting. Before you start a reboot, check if the problem is really in the overbank itself, not the cable, charger or plug-in gadget. Here are the typical symptoms that reboot helps:

• 🔄 Indicators burn chaotically or show an incorrect charge level (for example, 100% when the battery is discharged).
• 🔌 USB-Ports do not work: the superbank does not charge the phone / laptop, but it itself charges from the network.
• ⚡ The device does not turn on after full discharge or long storage.
• 🔋 Charging is jerky (it turns on, then turns off) or interrupted by 80-90%.
• 📱 The phone does not recognize the superbank (writes "Charging is not supported").

If Xiaomi's power bank just went down and didn't turn on, it's not always a breakdown. Modern lithium polymer batteries have deep-discharge protection, and the controller can block the operation before connecting to the power source, in which case you don't need to reboot: just connect the power bank to charge for 10-15 minutes.

⚠️ Warning: If the verbank is swelling, making extraneous sounds (hisping, crackling) or basking unloaded, don't try to reboot it. These are signs of critical battery wear and further use is dangerous! Take the device to a service center or dispose of it.

Method 1: Classic button reboot (for models with power button)

Most Xiaomi superbanks have a physical charge-check button, which is also used for software resets.

• 📦 Mi Power Bank 2/3 (10000/20000 mAhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh)
• 📦 Redmi Power Bank (10000/20000 mAhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh)
• 📦 Mi Power Bank Pro (10000 mAh, USB-C)
• 📦 Mi Pocket Power Bank (5000/10000 mAhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh)

To restart the device:

1. Disconnect all cables from the overbank (input and output).
2. Press and hold the switch on for 10-15 seconds.
3. Release the button when the indicators are turned off or flashed in sync.
4. Connect the verbank to charging for 5-10 minutes, then check the work.

If the indicators don't respond, try pressing the button 2-3 times in a row at 1 second intervals. Some models (e.g. Mi Power Bank 3) recognize this sequence as a reset command.

Method 2: Forced discharge through full discharge

If the button doesn't work or it doesn't (as in Mi Power Bank 1S), you can reset the controller by completely discharging and recharging the device, which works with built-in deep discharge protection, which reboots the controller when it reaches a critical charge level.

How to do this:

1. Connect a load to the superbank (for example, a smartphone or a lamp) and wait for the full discharge.
2. Leave the overbank off for 1-2 hours.
3. Connect to the charger (preferably the original one) and hold for at least 30 minutes, even if the lights aren't on.
4. Press the on button (if any) or simply plug the gadget in to check.

This method helps in 70% of cases when the overbank is “hang” due to a failure of the controller, but it is not suitable for devices with a badly worn battery (capacity below 50% of nominal value) – they may not turn on after discharge.

⚠️ Note: Do not use high-consumption devices (for example, laptops or powerful power banks) for discharge. LED-lamp-light 5W. Too fast a discharge can damage the controller.

Method 3: Reset via charger (for models without a button)

Some Xiaomi power banks (such as Mi Power Bank 1S or Mi Ultra Compact) do not have a physical button, in which case the reboot is performed through the charging connection cycle:

1. Connect the overbank to the charger (preferably with a 5V/2A output).
2. Wait until at least one indicator lights up (usually 5 to 30 seconds).
3. Turn off the cable from the superbank, wait 10 seconds.
4. Reconnect 3-5 times in a row. The controller should reset.

If the indicators don’t light up, try:

• 🔌 Use a different cable (preferably the original one from Xiaomi).
• 🔌 Connect to another charger (e.g. from a smartphone).
• 🔌 Change the port (if the bank has several ports) USB-exits).

This method works by resetting the controller state when the power is repeatedly connected/disconnected, and is less reliable than hardware reset, but often helps with the "hang" of indicators.

💡

If the overbank is not responding to charging, try connecting it to your computer via USB. Sometimes a weak current (500 mA) helps to wake the controller.

5. Method 4: Reboot through deep freeze (emergency method)

If Xiaomi’s overbank doesn’t turn on or react to other methods, you can try short-term freezing, which works because of the physical properties of lithium-ion batteries: at low temperatures, their internal resistance changes, which sometimes helps to “reset” the controller.

How to do this:

1. Place the overbank in a sealed bag (to avoid condensation).
2. Place it in the freezer for 15-20 minutes.
3. Take out and let it heat up to room temperature (1-2 hours).
4. Connect to charging for 30 minutes, then check the work.

This is a non-guaranteed way to help, but in some cases, it brings the power bank back to life. Don't use it often, because extreme temperature changes shorten battery life.

⚠️ Warning: Do not put the verbank in the freezer near the groceries or for a long time (more than 30 minutes). Condensation can damage electronic components, and deep freezing worsens battery capacity.

6. Method 5: Hardware reset (disassembly and disconnection of the battery)

If all previous methods have failed, the last resort is to physically shut down the battery, which requires disassembling the overbank and is only suitable for users with experience in electronics, and Xiaomi’s warranty will be lost!

What you need:

• 🔧 Plastic blade or mediator for opening the body.
• 🔧 Screwdriver (usually cross, size depends on the model).
• 🔧 Multimeter (optional, to check the voltage).

Step-by-step:

1. Carefully open the body, starting with the seam. Be careful - many models have latches that are easy to break.
2. Find a battery connector (usually a white connector with 2-3 wires).
3. Unplug the connector for 10-15 seconds, then plug it back in.
4. Get the case together and check the overbank.

If the battery is not turned off, there may be a faulty controller or damaged battery cells, in which case professional repairs will be required.

💡

Turning off the battery is the most reliable way to reset, but it voids the warranty and requires care. Don't take a swerbuck if you're not sure about your skills!
