Hi --I have purchased a USB LED light that come as part of a circuit that has a motion detector and a USB plug for power. I need to power this so it will be portable and thought a USB power supply would be the perfect thing. Problem is that when plugged in to a portable USB Power Supply and after it has turned the light on, set itself up and then turned the light off--to indicate it is motion detector mode--the power supply stops supplying power. I have tried two different power supplies and have identical results. I am assuming that the motion detector draws so little that the power supply thinks it's a charged battery and turns off. Can anyone suggest a way to disable power supply mode or even a different method to obtain power. My knowledge of electronics is very out of date so I apologize if I sound like an idiot to you people. --Thanks
