Ambrane P-2000 20800 mAh Power BankBlack, Lithium-ion

Got it at deal of 999 during sale and it's good enough at this price tag boasting 20800 mAh. Built quality is also good and works fine for my Redmi Note 3. Though takes much time to charge completely but that's justified with its power.

To describe this product to you in one word would be "Awesome". It is such a powerful charger and you can charge 3 devices at once. Standard Description : Power : 20800 mAh Output : 3 Ports (2 ports with 2A capacity and one port with 1 A capacity) Input : 1 Port LED torch In Package : Powerbank and diff data cable both for Android phones and iphones. Pros 1) Very powerful charger (figure 20800mah says it all) 2) can charge 3 device at once. 3) LED torch Cons Product is a bit bulky and takes a long time to get fully charged due to its enormous capacity.

buy this and you'll never run out of charge. A bit bulky though. Plastic quality could've had been better
