The root of the question comes from my experiences breaking laptop chargers because I didn't first check the amp supply, and wondering why this principle doesn't apply to (most) USB devices I use. As mentioned by you @JakeGould and in the accepted answer, being aware of the negotiated power draw in USB protocol is the basic info I was missing, as confirming the existence of this mechanism and its specific details is what the question is about. | |
