Fake Batteries Found In Xiaomi Power Bank T10.4
This power bank was bought by my son for a cheap price, knowingly well that it could be a fake, and brought it to me for opening and checking it up. Just see what was inside:
Just one cell along with three heavy plastic battery look alike for sizes. There is no mention ‘made in China’, though we all know these come from there!
In order to study whether I can add three more cells in it, I removed the IC, as the top was blank.
I could not read the IC number, however I tried. So, looking for a possible chance of getting a datasheet was ruled out.
Nevertheless, my son bought three batteries of similar type which I connected in parallel and switched on. It was working fine with blinks. Left it for charging until all the LEDs lit up and tried connecting it to a mobile. The discharge was fine too.
Thus an experiment was successful and my son took it with him for his standby use. Another job done satisfactorily!
