The Xiaomi Mi 10400 mAh power bank is one of the most popular power banks in town, and why not? For only RM 36 (~US$ 11.50), you get a really slick and well-made power bank with four high-quality 18650 lithium-ion cells. That's DIRT CHEAP, especially when it comes with the following quality components :

Texas Instrument BQ24195 lithium cell charger (92% charge efficiency at 2 A)

ABOV 8-bit microcontroller with a 12-bit analogue-to-digital converter

Four units of LG or Samsung 18650 lithium ion battery cells (each with a capacity of 2600 mAh)

So how does it look like inside? That's what we intend to show today with this teardown of the Mi Power Bank. Take a look!
