My data was based on actual riding, not on a lab measurement where you never stop. I used a meter to measure milliamp hours and time.
Based on this graph, up to about 20 km/hr, all the chargers are about the same except the Forumslader is much greater output. My measurement is from a Sinewave Revolution. Above 20 km/hr is were some chargers deviate from the mean.

That graph is from this english translation of the original German.
