Ive used the 10000 mAh powerbank but now I shifted to its 20000 mAh version. it's good guys. the design is not so cool. A typical black powerbank with white layers on the side. But it gives a good amount of power. I even gifted it to my dad. I can charge my phone atleast 4 times from 0-100% at a single charge. I got it at 999 from amazon on the great indian sale. its value for money guys. its more than just durable. The powerbank has fall from my hands atleast 13-14 times but a single scratch doesn't happen. I am very happy with my powerbank. If u r looking for a powerbank u can definitely buy it.
