Arduino Uno power input - is 5 V at 1 A enough? I have a Arduino Uno board and phone power bank

Power bank details


Capacity - 8000&nbsp;mWh
Input  - DC 5&nbsp;V and 1&nbsp;A
Output - DC 5&nbsp;V and 1&nbsp;A


Can I give the power to Arduino Uno using this power bank, through the Arduino Uno USB?
I dont see why not - YES you can!

I regularly use usb powerbanks to power projects for testing. so long as you dont ask for too much current (unlikely but project specific) you will be fine!
