Введение
What to do if Xiaomi Mi Power Bank 2S suddenly does not charge phone nor charge itself and only action is faint battery level LED jerking? This may be answer.
Kid complained about his USB power bank. It refused to charge phone nor charged itself. On cable connecting and button pressing power bank responded with faint random battery level LED jerking. No rattling inside or noticeable physical damage. Started to think about too discharged battery when charging controller can refuse to charge. The only option left was disassembling to see what happened.

Xiaomi Mi Power Bank 2S appeared easy for basic repairs. Glued parts are easy to remove and they stick back just fine. Internals are fixed by screws. Other Mi USB power banks from 2 line (2c, 2i) are built in same way.
Described USB power bank have good charging capacity and is easy for everyday use. Keep in mind that design is not rugged and battery terminals inside are thin metal strips. Try to avoid dropping it on hard surfaces. Kid admitted that he droped his power bank several times - hard to hide dents at outer case corners :)
