It features a 20,000mAh capacity and supports 22.5W charging through a built-in cable.
Inside, the device uses two 10,000mAh battery cells instead of a single large cell.
Xiaomi says the power bank passed rigorous safety tests, including a 4mm needle penetration test, a 135°C heat exposure test, and an overcharge test at 1.3 times normal voltage.
It also underwent a compression test with roughly 1.3 tons of force and a 300-cycle aging test that checks for lithium plating.

The device includes smart management features tied to its cable, allowing users to check battery health and access traceability information about the battery.
For connectivity, it offers one USB-A and two USB-C ports.
The new model is based on the Xiaomi 20000 22.5W Power Bank 2026, launched in June, and shares the same built-in cable, 2C+1A port layout, and price.
China's New National Safety Standard
China introduced a mandatory national standard for power bank safety on April 3, 2026, which will take effect on April 1, 2027.

The rules require stronger protection against high heat, overcharging, and crushing, and add a new test for lithium buildup after repeated charging cycles to reduce short circuit risks in older batteries.
Power banks must also store and share data about unusual events, and each unit needs its own identification code so consumers can check details like the battery brand.
The standard was developed with input from major manufacturers including Huawei, Xiaomi, Oppo, and Anker, and is considered one of the strictest globally.
It introduces extra mechanical tests such as drops, crushing, and impacts, bans the use of recycled or refurbished lithium cells, and sets tougher rules for the chemical fluid inside batteries.
