“The Nano Overlord requires 50mA at 9VDC with a center negative plug. Use of the wrong adapter or a plug with the wrong polarity may damage your Nano Overlord and void the warranty. Do not exceed 10.5VDC on the power plug. Power supplies rated for less than 50mA will cause the Nano Overlord to act unreliably.” source
