Will a 5V 300mA USB device run safely off of 3 AA Batteries?
I'm trying to make a 5V 300mA USB device portable, but I don't know how to measure/calculate milliamps for anything. What's the mA on 3AA Batteries? Pretty sure the voltage is 3.5, but please correct me if I'm wrong.
Basically: if I chop the USB connector off and wire the device to 3 AA's, will the device operate safely, or will it get damaged?
