We’re planning on doing our charging from a Bob trailer’s wheel.

Fahrrad Zukunft conducted the testing. I’ve never had an issue running my iPhone directly from my Plug III, but if you are concerned, you can always add in a cache battery to your dynamo charging system.

Did You test this?

Noted! I’m trying to keep it all as easy as possible to understand in a practical sense, so might go with hub drag.

You mean it similarly to air resistance, so a much less confusing choice would be input power, or to be even clearer, mechanical input power. Hub drag as Simon and you discuss is also a better choice, but drag typically implies completely lost power, which this is not.

The drag is very low when there is nothing drawing power: https://www.cyclingabout.com/dynamo-hub-drag-lab-testing/
