Question about power Arduino

Hello guys.

Can power arduino via power bank??

My project is Arduino Uno, Motor Shield, 2 DC motor, and Bluetooth kit (HC06).

Sure, your other parts should draw enough current to keep the powerbank satisfied to stay on.

The powerbank puts out 5V? Connect to the 5V power header.

Something like that. Is ok?

with two outputs so i can use one for Uno and one for Motor Shield.
