Can I reuse a charger (AC Adapter) on another device?
Polarity, volts, amperage and interface are the variables. Suppose I have left over AC/DC adapter from one device. And it has the proper male female plugs to connect. What if the device (eg my desktop scanner) expects +voltage on the outer ring and - on the interior (+/-), but I plug in an adapter that is -/+? What if adapter voltage output is lower/higher than expected by the device? Same question with amperage.
