Xiaomi’s 20000mAh, 45W output Mi Powerbank 3 Pro teardown shows the internals.
About a month ago, Xiaomi unveiled the Mi Powerbank 3 Pro which is the third-generation of power bank the Chinese firm is launching. Xiaomi has got quite a number of power banks in the market but the Mi Powerbank 3 Pro takes things to an entirely new level. The stand out feature, apart from its huge 20,000mAh capacity, is the 45W USP PD input and output support it comes with. The powerful output capacity can charge small and like notebooks such as Apple MacBook, Xiaomi Notebook laptop, Lenovo ThinkPad, Dell and HP notebooks. It can also charge mobile phones and tablets as well.  In addition, this mobile power supply also supports a small current charging mode, which can charge small power devices such as Bluetooth headsets and smart bands.

The Xiaomi Mi Powerbank 3 Pro utilises two USB Type-A and one bi-directional USB Type-C, all supporting multiple fast charging protocols. Among them, the USB-C interface supports 45W USB PD input and output . The powerbank uses two 10,000mAh batteries to give a robust 20,000mAh capacity. In order to enhance heat dissipation, the device comes with a large amount of graphite thermal paste inside to reduce the temperature increase of the board.
