Can you explain what do you really mean and how
does it relate to the problem?
It's my (poor) understanding that the power adaptor
is a constant *voltage* source, not a constant
*current* source.
In consequence the amperage drawn from it is only
dependent on the resistance of the device connected
to the output of the power supply.
And this follows Ohm's law:
current(in amps) = voltage(in volts) / resistance(in ohms)
In other words the adaptor will supply the device
with any amperage as required by the device, up
to the maximum value indicated on the label. Above
that, expect thermal breakdown.
