Let me guess... When you measured the current you placed the probes in parallel with the AP and the wall wart?
This would be wrong. You probably just damaged the wall wart and not the AP if this is the case. You're lucky if you didn't damage your meter. Current is measured in series. Meaning that to complete a circuit the power has to pass THROUGH your meter. To measure voltage you would measure the output of both the terminals of the wall wart in parallel. You must, however remember to move the probes on the meter from the current measurement location to the voltage measurement location. Most meters have 2 seperate locations for each. The current measurement jacks are internally connected together while the voltage jacks are a very high resistance. To figure out wattage in DC the correct formula is V * I = W where I is current. The best way to understand this is that current is the measurement of how many electrons pass through a certain point in a second (electrons in motion) or how many coulombs per second. 1 Amp = 1 coulomb/per second 1 coulomb = 6.25 X (10 to the 18th power) electrons 1 coulomb can also be a measurement of voltage which is just potential difference. So the difference of 1 coulomb (electrons not in motion) between to points would be 1 volt. So if you had a potential difference of 5 coulombs and the flow rate was 2 coulombs per second this would translate into 5 volts at 2 amps or 10 watts. Make sense? Dan.
