I'm trying to get an idea of how much power on average and at maximum
an XO-1.5 (with its power adapter) draws when being used while plugged
in. It doesn't help that I don't know much about electricity :(

Obviously, 'on average' is a spurious measure, but a rough idea would suffice.

What I can tell you is that our individual power adapters have the
following characteristics:

  * input 100-240V AC 50/60Hz
  * output 12V DC 2500mA
