Solved Can I Reuse A Charger Ac Adapter On Another Device Electronics
Chosen Solution 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?...
