Not sure how is the power bank is designed.
Since it is used to charge smart phones for long talk time and during travelling. I guess the voltage and current output from the power bank are regulated and controlled as handphones seldom need more than 5V DC or 500mA for charging. Your robot may need 7.6V or maybe 12V for the motors' operation. So make sure that the voltage and current output from your power bank are correct before purchasing the device.
