Nice power bank but not truly of 20000mah it drains very quickly while charging devices
18 August 2018
I have been using this power bank from months its working good, properly charging the devices but i believe the power bank is not of 20000 mah as when i charge my phone of 2500 mah battery from 4 or 5% to 100% the power bank's battery is almost half drained out it flashes only 2 led out of 4 leds of power bank which is half charged power bank indication........
So, the 20000 mah backup of power bank is not true for me
