12V / 15.6W power at the DC port, and ~48V for 802.3af or~54V for 802.3at using ~17.1W. General draw will be approx, as draw will be based on numbers of users, power of the radios, use of USB or second ethernet interface. There is no exact number in each case, as power can fluctuate at stratup and based on outside temperature as well, so you budget for the max draw always.
