Watt is the energy used. Watts is about the same on both sides of a power supply. Watt calculated like this:
volts x amps (also called VA)
Adaptor 110 x 1 = 110 watt
But why the output is written: 3.0-36vdc 3.0 - 0.41A i can't explain, but i belive that the greatest power in the whole area is 3 amp ( 3 x 36 = 108 watts, and 2 watts i power loss)
USB hub 5 X 2 = 10 watts
TQ Here is a large gap between indput and output.
110 x 2 = 220 wats
12 x 2 = 24 watts and 5 x 2 = 10 watts total: 34 watts.
The 2 amps could easily be a safety margin.
But if the only power consumption is only the 12 and 5 volts I belive that that max consumption is about 40 watts.
Abaut the computer power consumption I think the best solution is to buy this unit:

Or you can read on the powersupply it's power consumption, then you have the maximum wattage
But remember that you always have approxematly the same wattage on input and output side (a little more on indput side). If not then is eternity machine is invented :cool:
