USB type A male-to-female inline ammeters are really cheap, and accurate to 0.1W. I got one for ten bucks.

How do you know THAT doesn’t have a surveillance device inside?

Sort of a "it's turtles all the way down" type problem, but one could always x-ray it.

+/-20mA seems a bit coarse...with modern low-power silicon, imagining it wouldn't be too difficult to skate under that radar.
