Hi, I got a Linksys BEFW11S4 wireless router, and need to know its power consumption (in watts). I contacted Linksys support, they told me it was 10 watts. Now, I know that I already got an answer for my question, but I don't know if the answer is correct.
The AC adapter on the device has 2 readings, and I don't know which is the one to go by. Input: 110-120V, 0.5A Output: 5V, 2.0A
Now, watts=volts*amps, but why are Linksys tech support reading the "Output" line as power consumption (which gives 5*2=10 watts)? Isn't it the "Input" that determines the power consumption? In this case, that'd be ~50watts.

you sure you read the input specs correctly? Normally it's given in 120VAC, XW not XA
