The power adapter output voltage needs to be equal to the input voltage of the powered device (or the power supply device specifies that the input voltage is within a range and the adapter output voltage is within this range).

The output current of the power adapter is the maximum current that the adapter can output. The actual output current is determined by the powered device. (Simply, it depends on the impedance of the consumer (external resistance) and the impedance inside the power adapter (internal resistance) I=U/(R +R outside).

The (maximum) output current of the power adapter actually characterizes its internal resistance (the larger the output current, the smaller the internal resistance, that is, the power consumed by the adapter itself is small, and the power for external use is large).

Therefore, whether it is possible to exchange the input current of the nominal use of the equipment. The nominal input current of the consumer is less than the output current of the power adapter. Otherwise it will not move, but it will not damage the device.
