Why it is important to be able to turn off power bank and when it is necessary
Xiaomi Power Bank 10000 3 external battery (PLM03ZM model) is one of the most popular devices for backup power to smartphones, tablets and other equipment. Despite the simplicity of design, many users are faced with the question: how to turn it off correctly? It would seem that it could be easier to press a button and ready. But in practice, it is not so clear.
Powerbank shutdown is required in several cases: long-term storage (for example, if you do not plan to use it for several months), transportation in the planeβs luggage (according to air travel rules), saving charge with rare use or troubleshooting (for example, if the device is βhangyβ and does not respond to presses). Incorrect disconnection can lead to a deep discharge of the battery, which reduces its life, or even damage to the controller β the βbrainβ of the power bank responsible for charging safety.
In this article, we will discuss all the official and alternative ways to turn off Xiaomi Power Bank 10000 3, and also tell you what to do if the device does not respond to standard methods, you will learn how to avoid typical errors and prolong the life of your external battery.
Official method: switching off the power button
The most obvious and recommended method by the manufacturer is to use a physical button on the case. On the Xiaomi Power Bank 10000 3, it is located on the end next to the charge indicator.
- Short press (less than 1 second) β check the level of charge (LEDs light up).
- Long press (3-5 seconds) β switching on / off the power supply on USB-port.
To turn off the powerbank:
Press and hold the power button.
Wait until all indicators go out (usually 3-5 seconds)
Release the button β the device completely shuts down-->
Important: If a charger is connected to the power bank (for example, it is charged from the network), the switch off may not work. In this case, first disconnect the cable, then try again.

If the charge indicators flash after switching off, it could mean that the controller is still active. Give the device 10-15 seconds to shut down completely.
Automatic Shutdown: When Powerbank Shuts Down
Smart electronics Xiaomi Power Bank 10000 3 provides several scenarios of automatic shutdown, which should be considered:
- π No load: If no device is connected to the power bank for 30 to 60 seconds, it automatically stops power supply to the power bank. USB-It's a protection against overheating and unnecessary energy use.
- π Critically low charge: At a charge level below 5%, the device shuts down to avoid deep discharge of lithium-ion cells.
- β‘ Short circuit or overload: If the connected device consumes too much current (e.g., above 2.4A on one port), the controller urgently shuts down the output.
Automatic shutdowns arenβt always good, for example, if you plug a low-power device into a power bank (like a fitness bracelet or Bluetooth headphones), it may not wake up outputs because of too low current, in which case a long-pressed forced turn on will help.
Always.
Only before long-term storage
Never turn it off.

What to do if the power bank does not turn off: diagnosis of problems
Sometimes Xiaomi Power Bank 10000 3 can "hang" - do not respond to the press of a button, continue to serve power or, conversely, do not turn on.
| Symptoms. | Possible cause | Decision |
|---|---|---|
| Does not respond to the button, the indicators are constantly on. | Controller freeze due to voltage surge | Turn off all cables, hold the button for 10-15 seconds |
| Spontaneous on/off | Moisture or mechanical damage | Dry the device for 24 hours in a dry place |
| The indicators flash in a chaotic order | Failure of the battery cells | Contact the service center (replacement of the battery is possible) |
If standard methods donβt help, try resetting the settings:
- Connect the power bank to the charger (5V/2A).
- Hold the power button for 15-20 seconds.
- Release the button and turn off the cable. The device needs to restart.
What happens if you leave the power bank on for a long time?
Shutting down before storage: how to maintain battery capacity
If you plan to stay off the power bank for several months (like winter or on a business trip), it needs to be properly prepared. Lithium-ion batteries spoil from two things: deep discharge (below 20%) and long-term storage at 100% charge.
Optimal algorithm:
- Charge the power bank to 40-60% (2-3 LEDs on the indicator).
- Turn it off with a long press of a button.
- Store in a dry place at a temperature of 10β25 Β°C (not in the refrigerator!).
- Check the charge level every 3-6 months and recharge up to 50% if necessary.
Why 40-60%? At this charge level, the chemical processes in the battery slow down, and the risk of degradation is minimal. Storage 100% accelerates the oxidation of the electrodes, and by 0% leads to irreversible loss of capacity.

Storing a depleted power bank is the main reason it fails, and even after a year of 0% downtime, it may not be possible to restore it.
Can I turn off the power bank while charging another device?
Technically, yes, but it's not recommended. If you turn off Xiaomi Power Bank 10000 3 during power transfer, it can lead to:
- β‘ Abrupt power failure of the connected gadget (risk of data loss or file system damage).
- π Failure of the power bank controller (in rare cases, flashing is required).
- π Accelerated battery wear due to incorrect discharge cycle completion.
The exception is if the connected device is already fully charged (for example, the smartphone shows 100%), but the power bank continues to supply current, in which case you can safely press the switch off button.
On Xiaomi Power Bank 10000 3, the indicators burn constantly during active power transmission and start flashing slowly when the current drops below 0.1A (actually the charging is completed).
Alternative ways to shut down: when the button does not work
If the mechanical button fails or the power bank does not respond to the presses, there are several workaround methods:
- Discharge before automatic shutdown: Connect a low power device to the power bank (e.g, LED-flashlight or fan) and wait until it is discharged to 0.
- Use of Discharge Charger: Some smart chargers (such as the Xiaomi ZMI QB820) have battery discharge mode. Connect the power bank to such a device in Discharge mode.
- Short-term closure of outputs (for experienced users only!): β οΈ Attention, this method is risky! + and USB-port with a metal object (e.g., a paper clip) for 1-2 seconds, which simulates the connection of the load and can "wake up" the controller to then turn off the button.

If you're exposed to power bank freezes, check the cables and adapters. Poor wires with damaged insulation can cause power surges that knock the controller down.
