The source of the power does not matter. The ability of the source to supply the needed voltage AND current does. Most USB chargers are meant to charge phones and bluetooth devices and other low current devices.

Hi,
     It depends on the motors and the sheild, if the shield uses an L293 or L289 then you are going to lose power (2v+) in the output transistors, something like the DRV series IC's or modules are a lot better.

Having said that I often use 2 x AA Lith which gives me 7.2v this can also be fed to the Arduino Vin pin to power it.

Take a look here, under electronics: http://www.melsaunders.co.uk/

Hope it helps, regards.
