Samsung N7000 Note. The Samsung charger is spec'd at 5.0v, measures 4.92v. Just checked my various other AC/USB adapters and 12v auto adapters and measured between 5.06v and 5.16v. After reading this: http://www.apogeekits.com/power_adapter_selection.htm, I come away with the expectation that the voltages will fall once the chargers (unregulated, I assume) are actually charging a battery.... but I don't have a clue how much. The Question: Is it worth the expense of buying Samsung adapters to get something that's at or below 5.0v... or is the diff between that and, say, 5.2v not significant in terms of diminished battery life?
