How to turn off Xiaomi Power Bank 20000 mAh: all the ways and nuances

Why it is important to be able to turn off the power bank and when to do it

Power Bank Xiaomi 20000 mAh is one of the most popular portable chargers on the market due to its capacity, compactness and reliability. However, many users are faced with the question: how to properly turn off this power bank if it is not equipped with an explicit power button or continues to run out in standby mode? Unlike smartphones, where the on/off button is always in sight, external batteries often have hidden controls.

Powerbank shutdowns can be needed in several ways: to save charge during long-term storage, during transportation (for example, in an airplane), if the device has begun to overheat or behave unstable. In addition, some Xiaomi models automatically go to sleep after 10-15 seconds without loading, but do not completely shut down, continuing to consume energy. In this article, we will discuss all official and alternative ways of turning off, including resetting settings and working with different versions of the firmware.

We will focus on Mi Power Bank 2/3 (20000 mAh), Redmi Power Bank 20000 mAh and their modifications, as the algorithms may differ, and consider why some Xiaomi power banks do not turn off in the standard way and what to do about it.

How to turn off Xiaomi Power Bank 20000 mAh: official instructions

The standard way to turn off depends on the model and year of the device. Most Xiaomi power banks do not have a separate shutdown button, instead using a combination of actions with a charge check button.

1. A brief press of the button (1-2 seconds) – check the level of charge (indicators light up).
2. Long press (5-10 seconds) – forced shutdown / turn on.
3. Double pressing (with intervals <1 sec) – activation of low power mode (for some models).

For Mi Power Bank 3 20000 mAh (PB2003ZM) and Redmi Power Bank 20000 mAh, the official instruction recommends:

1. Connect the power bank to the charger (even if it is fully charged).
2. Hold the charge check button for 10-15 seconds until the indicators go out.
3. Turn off the cable, the device will go into deep sleep mode.

If this method doesn’t work, your model may support automatic shutdown after 30 days without use (Auto Power Off feature).

Why Powerbank doesn't shut down: Common reasons

If your Xiaomi 20000 mAh doesn’t respond to a long push of a button or continues to run out when it’s off, the reasons may be:

• 🔋 Charge below 5% – the device blocks the shutdown to avoid deep battery discharge.
• 🔌 Connected device – even if the cable is not connected to the smartphone, the connector USB may be active.
• 🤖 Firmware failure – especially relevant for Bluetooth models (e.g. Mi Power Bank 3 Pro).
• 🌡️ Overheating or hypothermia - at a temperature below 0°C or higher than 40°C Powerbank can ignore commands.

A common problem for Redmi Power Bank 20000 owners is a false alarm, for example, if the device was discharged to zero and lay uncharged for a long time, the controller can block the shutdown, in which case the full charge-discharge cycle will help:

1. Connect the power bank to the network for 12+ hours (even if the indicator shows 100%).
2. Discharge it before automatically shutting down (plug your smartphone and wait for the shutdown).
3. Re-charging - after that, the off button should work.

Alternative Shutdown Methods: Resetting and Forced Shutdown

If the standard methods didn’t work, you can try hardware reset, which is suitable for most Xiaomi models, but requires caution:

Charge the device to a minimum of 30%|Use the original Xiaomi cable|Press and hold the 20 button+ seconds|Disconnect all devices from USB-port

-->

For Mi Power Bank 2 20,000 mAh (PLM05ZM) and similar models:

1. Connect the power bank to the charger (required!).
2. Hold the charge check button for 20–25 seconds until the lights start flashing in non-standard mode (for example, all 4 lamps will light up at the same time).
3. Release the button - the device will reset and turn off.

For models with a Bluetooth module (for example, Mi Power Bank 3 Pro), you can use the Mi Home mobile application:

1. Connect the powerbank to the application via Bluetooth.
2. Go to the device settings → Power management.
3. Select the option of Deep Sleep or Forced Shutdown.

⚠️ Warning: Forced reset can reset the charging cycle counter and other service data. Do not use this method more than 1 time every 6 months.

Model comparison: how to turn off different versions of Xiaomi 20000 mAh

The shutdown algorithms may vary depending on the generation of the power bank, and the following is a table with the main characteristics:

Note that Redmi Power Bank 20000 and Mi Power Bank 3 Pro require you to connect to the app to shut down completely.This is due to the presence of a built-in Bluetooth controller that manages power consumption. If you lose access to the application (for example, changed your smartphone), the only way to turn the device off is to drain it to zero and then fully charge it.

💡

If your powerbank supports Bluetooth but does not connect to Mi Home, try resetting the connection: hold the 10 seconds button until the Bluetooth indicator flashes quickly (blue).

What to do if the power bank does not turn off at all: diagnostics of malfunctions

If none of these methods worked, maybe the problem is a hardware malfunction.

• 🔥 Overheating on shutdown – a faulty charge controller or short circuit in the battery.
• 🔄 Cyclical reboot – firmware failure or control chip damage.
• 🚫 The button does not respond – contact oxidation or mechanical damage.
• ⚡ Spontaneous switching on - failure of the power transistor.

For diagnosis, follow the following steps:

1. Check the indicators: If you press a button, only 1 light bulb is a battery problem; if the lights flash randomly, the controller fails; if the lights don't burn at all, the circuit break or the deep discharge.

Check it out. USB-port

• Connect a known device (like a flashlight) if it's charging, the problem is the button.
• If the port does not produce voltage, the DC-DC converter is defective.

How to properly store power bank Xiaomi 20000 mAh

If you plan to avoid using the power bank for a long time (for example, during vacation or seasonal storage), it must be properly prepared to avoid battery degradation.

• 🔋 Charge levels are optimally 40-60%, and full charge (100%) or discharge (0%) accelerates the aging of lithium-ion cells.
• 🌡️ Storage temperature - from 10°C to 25°C. Avoid refrigerators, attics or cars in the sun.
• 📦 Packaging – use the original box or antistatic bag. Do not store near metal objects.
• 🔌 Shutting down all ports – even if the power bank is turned off, a connected cable can discharge it.
