I bought this on 21-10-2018. It claims to be 10000mah battery but after use of 7months I can say that it was just 7000mah but at this price it was the best... It got this power bank white in colour at just ₹501 from flipkart during season sale.. it works good...And yes it comes with a year warranty. It has fault during Feb 2019 and I called flipkart to claim warranty and belive me it was replaced and I got a new power bank within 2 days without any question about the product.simlilary I replace another product of flipkart smart buy so don’t hesitate to buy it as it was not a brand. It was the best brand as compared to another brands in terms of service, warranty claim and product quality. I recommend you to buy it once..It was best at this price
