I am currently using this powerbank and must say it is best under this price range. Mine colour is black and usb cable quality is also sturdy and look of powerbank is also great. Packing of powerbank is great and they delivered it safely. This is made in INDIA powerbank so I choose it to buy. Capacity is 20, 000 mAH and charge my redmi note 4 almost 3-4 times. Buttons on powerbank is also responsive and presence of LED light makes it a complete and compact powerbank. Charge output is also awsome and they call it smartcharge. It can charge two device at a time.
