Xiaomi 20000mAh Power Bank Specifications
The Xiaomi power bank features a massive 20,000mAh battery capacity powered by two 10,000mAh lithium-ion cells. These cells deliver an effective rated capacity of 12,000mAh (5V/3A) and an energy rating of 74Wh, meeting international aviation standards, ensuring it’s safe to carry on flights.


This power bank equips a built-in USB-C cable for dual-way fast charging, simplifying portability by eliminating the need for additional cables. It is compatible with a wide range of devices, including Android phones with USB-C ports and all iPhone models starting from the iPhone 15 series.
It sports a maximum fast-charging output of 22.5W, ensuring swift power delivery to your devices. For instance, it can charge a Xiaomi 15 Pro up to 31% in 30 minutes and an iPhone 16 Pro up to 56% in the same time frame. This performance is backed by Xiaomi’s intelligent charging technology, supporting fast charging in both input and output modes.
The power bank comes with three output interfaces: a built-in USB-C cable, a USB-C port, and a USB-A port, allowing simultaneous charging for up to three devices. The power bank also automatically recognizes and adjusts the current required by connected devices, ensuring compatibility with smartphones, tablets, Bluetooth headphones, and fitness bands.


Designed for safety, it sports multiple protection mechanisms, including temperature control, short-circuit protection, overcharge/over-discharge prevention, and overcurrent safeguards, ensuring reliability during use.
It features a minimalistic, elegant design, available in two matte-finish color options. Its compact dimensions (128mm x 73mm x 32mm) and lightweight build make it easy to carry and store. The power bank comes in light grey and dark grey color options.
