Call me crazy but surely you can't get all that power out of a AA. The way I see it the battery tells you what the device consumes by its rating ie 1.2v @ 2800 mah meaning you can do volts multiplied by amps to give you the rated hourly wattage of 3.36 watts or 3.36w/h. Now with the power adapter I cant see them exceeding the same spec much as the herb would get toasted meaning that the rest of the 12w they quote is losses in the transformation process of the adapter itself and would agree with the 12v @ 1250mah written on the power adapter power brick totaling to 15w and having 3w slack as to not be working flat out.
So 12 watts used lets assume they add a slight boost and it supplies 4 watts to the box so it draws 12 watts @ 240v to make 4 watts @ 1.2v thats a 3 to 1 ratio or 33.3% efficient.
If you notice what paka says it states that the mflb operates by "shorting" the battery. AA nimh will surly give you that kind of power when shorting it out.
