The most important details for you and your delicate electronics are the voltage and the current. Voltage is measured in volts (V) and current is measured in amps (A). The input of the device should be the same as the output of the adapter. This includes polarity. If the device has a DC input of +12V / 5.4A, get an adapter that has a DC output of +12V / 5.4A. If you have a universal adapter, make sure it has the proper current rating and that you choose the correct voltage and polarity.
