Err... how did you obtain the Ampere value? Hopefully not by
setting the voltmeter to a current range and connecting the tips
to the ac adapter plug? Since the Newton AC adapter has overcurrent
protection, you won't kill it that way, but don't do this to
cheap adapters unless you have a second voltmeter, a second adapter
and a second life. Electrically a voltmeter set for measuring currents
can be compared to a piece of wire...

I haven't yet had a chance to take an adapter apart. Depending on how
the connection between the prongs and the printed circuit board is made,
this may or may not be possible.
