Flipkart SmartBuy 11000 mAh power bank with Free additional 2A Fast Charging cableBlack, Lithium-ion

Very bad experience with this product I can't say anything about its performance because it's not working. Even After replacement it's 3rd port isn't working. So overall awful experience. Not recommended

"It is indeed welcome and refreshing to see Flipkart market it's own products. So i was surprised to hold this cool looking Powerbank with the Flipkart logo on it. It has a capacity of 11000 mAh. It weighs in at about 280g and is definitely in its class where heaviness is concerned and is of course lighter than 13000 mAh Powerbanks. The design is 'longer' than it is 'broader' and that makes it sleek to hold. It will fit into any standard Jeans Pant pocket comfortably. I got the black and grey dual tone matte finish colour. It feels like its got good grip to hold and wont slip unlike metal finished Powerbanks. Build quality is durable and solid. I feel it will survive drops well. But the finishing could be tad bit better, with the encasing lines and grooves fitting snugly instead of glaring gaps in the panels. It has four tiny blue non obtrusive LED's. These imply residual charge (remaining) levels as 25, 50, 75 and 100 %, as with any Powerbank. For the output there are three USB ports for you to connect any device that supports USB based charging. These ports have labelled dots. one, two and three dots for the three ports. one and two are 5v 1A ports while the port three is a 1.5V 2A fast charging...(not quick charging mind it) port. So it is recommended to use port 3 for rapidly charging your mobile (if it supports 2A currents....most mid range phones do, especially if they have a 3000mah battery or higher). There is a power on off button on the top, single press to power on, double press to power off. It will come on automatically if a device is connected for charging and it does auto shut off (30 sec) when charging cable is removed. Three devices can be charged at a time, Remember, Port 3 (3 dots) will charge the fastest. In the box you get 2 USB MALE A to Micro USB B cables. One is thick and the other is thin. Remember to use the thicker one for fast charging on Port 3. The thin one can be used on Ports 1 or 2 , and even to connect the Powerbank to a usb wall Charger or Laptop. And last but not the least, it does support 'Pass-through' charging. (....meaning you can charge your Powerbank and use it to charge other devices at the same time, while it is charging up) All in all, this is a good value for money Powerbank that is sleek to carry around in your handbag, shopping bag, car, bike, scooter, shirt pocket, pant pocket or use as a table top charging station. Recommended and a must buy if you are looking for one. "

I'm using it for couple of weeks. It serves good. Charges my phone faster but not so fast but it is ok. Grab it. And flipkart is offering home pickup in case of repair
