Xiaomi 67W Power Bank 20000 (Integrated Cable) FAQ

FAQ
Q1: Will the Xiaomi 67W Power Bank 20000 (Integrated Cable) automatically stop charging after fully charging a phone?
A: The Xiaomi 67W Power Bank 20000 (Integrated Cable) will not automatically stop charging. The power bank intelligently adjusts charging based on the phone’s requirements, following the phone’s own charging logic.
 
Q2: How is the charging power distributed when the Xiaomi 67W Power Bank 20000 (Integrated Cable) outputs through multiple ports simultaneously?
A: The actual output power of the Xiaomi 67W Power Bank 20000 (Integrated Cable) is intelligently distributed according to the connected devices, and it dynamically adjusts based on the remaining battery level of the devices being charged. In most cases, priority is given to the Type-C port output.
 
Q3: How to use the low-current mode of the Xiaomi 67W Power Bank 20000 (Integrated Cable)?
A: The low-current mode of the Xiaomi 67W Power Bank 20000 (Integrated Cable) is specially intended for charging devices such as Bluetooth headphones, bands, and watches.
To use the low-current mode of the power bank, please refer to the following information:
  1. After the power bank's USB-C port is connected to a low-current device, the power bank will automatically enter the low-current mode without manual operation. In this case, the power bank will not display the low-current indicator.
  2. If the USB-A port is needed to charge a low-current device, press the button twice. Then, the power bank will enter the low-current mode, and the display will show the low-current indicator.
The power bank can also exit this mode 2 hours later. The power bank can also exit this mode automatically by pressing the button twice or connecting to a non-low-current device. If this mode is not needed, exit in time to avoid power consumption.
 
Q4: How to turn on/off the Xiaomi 67W Power Bank 20000 (Integrated Cable)?
A: The Xiaomi 67W Power Bank 20000 (Integrated Cable) does not support manual power on/off. When connected to a device such as a phone, the power bank automatically begins charging without manual intervention. The power bank's built-in button is only for turning on/off the display and does not power it on or off.
If no device is connected, the power bank's charging port will not output power. Therefore, there is no need to worry about power consumption. After approximately 25 seconds without a device connected, the power bank will automatically shut down, and the indicator will stop flashing.
 
Q5: How many times can the Xiaomi 67W Power Bank 20000 (Integrated Cable) charge a device?
A: Since energy conversion loss occurs during the charging process, and different power banks have slightly different energy conversion efficiencies, the number of charges will vary. Therefore, an exact charging count cannot be provided.
The following are examples of the Xiaomi 67W Power Bank 20000 (Integrated Cable) for reference:
  1. It can charge the Xiaomi 15 about 2.61 times.
  2. It can charge the Xiaomi 15 Ultra about 2.56 times.
  3. It can charge the iPad Air 11-inch (M3) about 1.76 times.
  4. It can charge the MacBook Air 13-inch (M4) about 1.03 times.
 
Troubleshooting
Q1: Why does the Xiaomi 67W Power Bank 20000 (Integrated Cable) only charge an iPhone up to 80%, or sometimes fail to charge?
A: The Xiaomi 67W Power Bank 20000 (Integrated Cable) can only charge an iPhone to 80% or not charge at all for the following reasons:
  1. The iPhone has enabled the “Optimized Battery Charging” feature, which slows charging after 80% by switching to trickle input. Path to toggle: [Settings] >> [Battery] >> [Battery Health & Charging] >> [Optimized Battery Charging]. You can turn it off and try again.
  2. Running intensive tasks such as gaming, long video recording, or calls during charging can cause the iPhone to heat up. When the device temperature is high, the iPhone’s protection mechanism activates, which will slow down charging or even stop it.
 
Q2: Why does the indicator on the Xiaomi 67W Power Bank 20000 (Integrated Cable) keep flashing when an Apple data cable is connected, but not the phone?
A: This is normal. Since the Apple data cable contains a chip, it consumes a small amount of current when plugged into the Xiaomi 67W Power Bank 20000 (Integrated Cable). If the other end of the cable is not connected to a device, the power bank will intelligently recognize the cable as a "low-current device," causing the indicator to keep flashing.
 
Q3: Why does the Xiaomi 67W Power Bank 20000 (Integrated Cable) seem to lose power quickly when charging a phone?
A: The Xiaomi 67W Power Bank 20000 (Integrated Cable) supports fast charging, it can appear to discharge quickly due to its high output speed. Because of the high output power, fast charging will create the perception of faster battery drain. This is normal.
 
Q4: Why is there a current noise when the Xiaomi 67W Power Bank 20000 (Integrated Cable) is charging a phone?
A: Different phones have varying current fluctuations during charging. For example, iPhones can experience current fluctuations of several hundred mA. When the fluctuation frequency falls within the human audible range, a current noise could be heard. This is normal and does not indicate any risk to the Xiaomi 67W Power Bank 20000 (Integrated Cable) or phone. It is safe to use.
 
Q5: Why can’t the Xiaomi 67W Power Bank 20000 (Integrated Cable) enter fast charging immediately after exiting low-current mode?
A: The Xiaomi 67W Power Bank 20000 (Integrated Cable) will switch to fast charging after about 30 seconds. This is normal behavior.
