An information handling system powers a projector through a communication interface, such as a USB interface, by selectively enabling first or second power levels through the communication interface. Initially, the communication interface provides a first minimal power level to run a controller on the projector. The controller communicates with the information handling system to establish approval for power at a second level, such as by communicating an identifier or a power level to the information handling system. The projector approves a power draw at the second power level based upon information received from the information handling system. The projector draws power at a second level that is adequate to fully operate the projector for presentation of visual images.
