It's a OG product as my friend bought it from flipkart got the genuine product. Normal 10000mAh power-bank is charged the mobile upto 2 or 2.5 times but this power-bank can charged more than 3 times guaranteed. After the 1 month of use I a reviewing this. Thanks for this awesome product.

This is really a very good product. I charge my mi redmi note 4 phone 2 times when phone battery level was about 20%. Power bank level reduces 100% to 50%.
That is very good back up. BATTERY LEVEL indicator is also a additional feature.
