Hi guys last year I bought a 10000 mah power bank of xiaomi from that site first of all they delivered it late and after charging 2 or 3 times it stoped working. That power bank was of degraded quality and it had some charging issues now I am totally frustrated by its quality and performance. Now I am not looking forward to make a purchase from that site again and I not even recommend you to do so. And one last thing they don’t even provide you proper post purchase services, I am totally frustrated guys
