Hi guys this is an excellent power bank bought it for rs 800 from flipkart. It has a capacity of 8000 to 9000 MAH about 70-80% of 11000 Mah. It charge prety quickly faster then other conventional charger it has three port. While using two ports at the same time the device get heat up little bit but it charge very easily. And it takes 9 to 10 hours to get fully charge the power bank. I find it this power bank is very good at this price so go for this.
