Speaking from experience measuring the power draw of a single XO with these
low cost power meters is tricky. They can be very inaccurate at lower
power measurements. The kill-a-watt for example has a typical accuracy of
1% with a max of 4%. Full scale is 1800W
Good point. Thanks. It's even worse than that. In the power mode, the
Kill-a-Watt only shows whole watts, no fraction.
It's worse than that. IIRC mine only shows 6, 12, or 18 watts at that
low a value. Useless for really low power. I ended up using a test
board for a switching power

Is the XO running or powered off?
Is it for a XO-1.5 or XO-1.5?
Oops. XO-1 or XO-1.5
