Answer to: Can I reuse a charger (AC Adapter) on another device?Make sure the power adapter is not only the right voltage but is able to handle the needed power to supply your device with enough voltage to operate. The power formula P (watts) = I (ampere) x V (volts) shows you that if for example the needed power is 5 watts and the adapter delivers 12 volts, the adapter must be able to supply a current of at least 0,41 Amps (or 410 mA). There's no risk in selecting an adapter that is able to deliver a current of 1 Amps (1000 mA) at 12 volts. The device is not harmed by this. If the current is not enough, voltage might collapse causing slow charging of battery devices or inoperatibility of the device.
