I have found this power bank ( http://www.amazon.in/Penibel-PT-10-10000mAh-Technology-smartphone/dp/B01FY58PLG?tag=googinhydr18418-21&tag=googinkenshoo-21&ascsubtag=2c2001f7-f9b7-4db1-9b28-9403e817f186#immersive-view_1473098833799 ) and it uses some smartfit technology to detect how much input is required for device plugged into USB of power bank . This power bank has 2 USB output one I want plug into raspberry pi and other I want to plug into net gear wifi router that supports port forwarding ( since I want to self host ).
What is your opinion about going for this device ? I am only sceptical about smart fit technology but on the other hand it outputs 5v / 2.4 A which I guess is perfect for my pi 3!
