Tearing it down
If you're here for the Mi Power Bank review, you can probably stop reading now. However, because we still couldn't get over the fact that a quality 10,400mAh power bank can cost so low, we decided to rip one apart to see exactly what's inside. If you're fascinated by this kind of things, please carry on reading. Else, you can jump right to the conclusion at the end of this page.

Say, what do we have here? That's four LG (LGABB41865) battery cells, each 2,600mAh, for a total of 10,400mAh.

Xiaomi says that the Mi Power Bank uses control chips by Texas Instruments; and indeed, we found a TI BQ24195 switching charger.

Towards the left is an 8-bit microcontroller (ABOV MC97F1204SMBN) made by Korea-headquartered semiconductor company, ABOV Semiconductor.
