redwire Posted July 6, 2011 Report Share Posted July 6, 2011 If you are connecting to a computer you won't even come close to getting that kind of power. Typically the power is limited to 500 milliamps at 5 volts for USB 2.0 and 900 milliamps for USB 3.0. Different models may vary but that's around 2.5 to 4.5watts .
